Truck Mounted Attenuator (TMA) Workshop

“Helping Keep Everyone Safe ON ROADS”

1. INTRODUCTION

A. WHAT IS A TMA?

“TMA” is an acronym for “Truck Mounted Attenuator”, also known as a Protective Vehicle or Shadow Vehicle. All Nixon Engineering TMAs are used as Protective and/or Shadow Vehicles. TMAs are energy absorbing units designed to protect persons and property and to prevent and/or reduce injury or damage. A TMA is two units made into one: an attenuator is attached to a host vehicle.

Nixon Engineering’s TMAs weigh more than 19,000 lbs. and less than 26,000 lbs. and are no taller than 11 foot, making their specifications the legal weight and height for the State of Texas standards. There is no special governing authority that issues licenses to drive or operate a TMA. A Commercial Driver’s License is not required to drive or operate a Nixon Engineering TMA, due to its weight being less than 26,000 lbs.

Truck Mounted Attenuators are designed to absorb the energy of an errant vehicle. An errant vehicle is a vehicle that deviates or strays from the proper or designated course. For example, an errant vehicle is the vehicle that has violated the integrity of an established traffic control plan and as a result created damage and/or injury to persons or property.

B. WHY ARE WE STUDYING TMA?

This is a Nixon Engineering Workshop and guide only. This Workshop is produced for the purpose of insuring that each employee is aware of the nature of a TMA and the nature of his/her roles, responsibilities, and risks when operating a TMA. It will include basic knowledge about driving and operating a TMA in order that the driver or

Page of 6 41

operator have the benefit of having additional information when making decisions and judgments about their actions and reactions during an operation. This information is provided to further assist the TMA Operator in his/her endeavor to prevent likelihood of accidents and/or or enhance the TMA Operator’s ability to perform in the manner consistent with the purposes intended for use of a TMA.

Currently, there is no requirement to be Certified by any governing authority to drive or operate a TMA. However, TMA Operators should view themselves as protectors and be aware that the TMA is designed to accept an impact, and the TMA Operator is at risk of it happening while he/she is operating the TMA. TMA Operators need to be aware of the risk and accept it.

When accepting an assignment to operate a TMA, the TMA operator is consenting to and accepting the risk associated with actual performance of his/her role and responsibility in operating a TMA. This Workshop assists the employee in assessing and voluntarily assuming those roles, responsibilities and risks associated with driving or operating a TMA.

Further this Workshop provides additional knowledge of use, methods of use, transport, setup, operations, and preventative maintenance of the TMA.

If you would like to be certified with ATSSA, you may make written request to HR Manager at P.O. Box 1090, Bastrop, Texas 78602 and HRManager@thenixonhouse.com, and Nixon Engineering will consider the request and determine whether it will pay the fee for you to either attend the online class or classroom. ATSSA Certification is not mandatory in the State of Texas.

C. WORKSHOP OBJECTIVES

After completing this Workshop, you will have been presented with the following data for your consideration and use while operating a TMA:

1. Understanding a TMA and its purpose

2. Characterization of the TMA Operator

3. Equipment related to TMA and Traffic Control Plans

4. Operational Concepts of a TMA

Page of 7 41

5. Preventative Maintenance Requirements of a TMA

6. Understand unequivocally (without a doubt), that you have the right to stop any operation if you do not believe the conditions are safe. Do not operate a TMA if you do not feel safe, comfortable, or do not understand the Traffic Control Plan or your duties.

7. Reporting any and all matters timely and properly is very important.

8. Review of typical scenarios relating to TMA issues.

2. TMA OPERATOR CHARACTERISTICS A. QUALIFICATIONS OF A TMA OPERATOR

“To a certain degree, the amount of protection that is provided depends on the TMA Operator’s willingness to be attentive enough to make quick decisions based on good judgment”. Author unknown.

To be a qualified TMA Operator, you must:

• Be certified as a Flagger with Nixon Engineering;

• Possess a current, valid Texas Driver’s License;

• No DUI or DWI within the past 5 years;

Page of 10 41

• No more than 3 moving violations within the past 2 years;

• In the past three years, no major violations (careless driving, conduction a speed contest or racing, driving under the influence of drugs or alcohol, failure to leave name and address at the scene of an accident, fraudulent use of an operator’s license, hit and run, making false accident report, manslaughter or homicide arising out of the use of a motor vehicle, operating a motor vehicle during a period of license suspension or revocation, operating a motor vehicle without the owner’s authority to do so, reckless driving, refusal to submit to alcohol or drug testing, use of a motor vehicle in the commission of a felony);

• Be approved on Nixon Engineering’s Driver List; and

• Provide Signature of Completion of the Nixon Engineering TMA Guideline and Workshop, which is also presented in the Initial Flagger Four Hour Orientation and Training Program.

B. ROLE, RESPONSIBILITY AND RISK OF A TMA OPERATOR

1. Roles, responsibilities and risk any TMA Operator should consider include, but are not limited to the following:

• TMA Operator has a responsibility to prevent injuries and property damage for themselves, their employer and employer’s customers, and the general public including motorist or bystanders.

• Insure the TMA is properly placed and controlled in manner to accept and deal with an errant vehicle.

• TMA Operator must know, understand, and properly apply the designated Traffic Control Plan.

• TMA Operator should remain mindful at all times of the duty and challenges associated with continuous presentation of a clear message to the Traveling Public, in order that the Traveling Public be able to understand clearly how to proceed in and around the particular work zone.

• Understand and comply with applicable Spacing and Roll Ahead Distances.

• It is the responsibility of the TMA Operator to make sure the TMA is in the proper position to prevent injuries and/or property damage. The risk is that if the TMA is properly placed, it should be the unit that receives the impact of an errant vehicle, and as a result the TMA Operator should be prepared and accept that risk and maintain proper posture and control before, during and after any event of impact.

Page of 11 41

• TMA Operator role is to make sure that the TMA is in the proper location, provides ample roll-ahead distance, and offers adequate warning to protect workers from intrusion.

• TMA Operator should be able to be alert, attentive, aware, observant, and able to react to surrounding conditions, traffic, and roadway conditions.

• TMA Operator alerts others by using the Airhorn located by the driver-side door window, when possible.

• Consistently check rear view mirrors

• Maintain constant or appropriate levels of communication with co-workers and others as designated or appropriate.

• Understand and properly execute the applicable and designated Traffic Control Plan

• Wear properly adjusted seatbelt at all times and require all others to wear seatbelts at all times while operating the TMA.

• Wear Hard Hat, Vest and Steel-toed boots/shoes and pants while operating the TMA.

• Secure any and all loose items inside the cab of the TMA in the spare seatbelt or in the under-seat compartment while operating the TMA.

• Understand and properly perform TMA Operational Issues.

• Before and After use of TMA perform Checklist “Before Use – TMA Operational Issues”.

• Verify and perform the Employee Vehicle and Equipment Safety Review (EVESR), also found in the Safety and Vehicle Policy.

• Before each use perform the “Before Use - TMA Scorpion Maintenance Intervals”.

• Participate in supporting the Monthly and Annual TMA Maintenance Intervals. All also are found in the Safety and Vehicle Policy.

• Participate in performing Maintenance Schedules of the vehicle, when requested.

• Participate in insuring the TMA is in proper working condition.

• Report any and all issues and/or concerns timely and properly.

2. Important Reminder of TMA Operator’s Right.

Page of 12 41

Understand unequivocally (in a way that leaves no doubt), that you have the right to stop any operation if you believe the conditions of the operations are unsafe or that any related matter is unsafe, including but not limited to the Traffic Control Plan and its application to the situation. Do not operate a TMA if you do not feel safe, comfortable, or do not understand and accept your role, responsibility or risks.

3. Other Considerations. Consider and review the following ideas and concepts for increased awareness of Roles, Responsibilities and Risks of a TMA Operator:

a. TRUCK MOUNTED ATTENUATORS

Truck Mounted Attenuators are energy absorbing devices attached to the rear of trucks used as protective and shadow vehicles. These devices are designed to protect the persons and property.

b. TMA as a PROTECTIVE VEHICLE

A protective vehicle is defined as any vehicle used to protect workers or work equipment from errant vehicles. An errant vehicle is defined as a vehicle that deviates or strays from the proper or designated course.

Protective vehicles are used to safeguard the work space from errant vehicles. In some operations, these devices also serve as platforms for arrow boards or message boards to warn traffic of upcoming conditions or inform them of needed corrective actions.

Protective vehicles should also provide sufficient warning to approaching traffic and maximum protection to workers and equipment. This means the protective vehicle should be positioned so that is clearly visible to approaching traffic, and the TMA’s position minimizes any vehicular encroachment into the prohibited spaces or locations. To minimize encroachment into prohibited spaces, consider that the TMA should maintain its minimum roll ahead distance between the vehicle and the protected area, as provided by the applicable Traffic Control Plan.

Trail Vehicles and Shadow Vehicles are Protective Vehicles.

c. TMA as a Trail Vehicle

Trail Vehicle which is also a protective vehicle that is located directly behind the Work Vehicle. The Traffic Control Plans describe the appropriate spacing and requirements for all Trail Vehicles and Protective Vehicles.

Page of 13 41

d. TMA as a SHADOW VEHCILE

A shadow vehicle is an additional protective vehicle that follows the Trail Vehicle. The Traffic Control Plans describe the appropriate spacing and requirements for all Shadow and Protective vehicles.

In mobile operations on a hill or curve, in a Shadow Vehicle, the TMA Operator should consider remaining on the hill or at the curve until the Trail Vehicle is far enough ahead of the Shadow Vehicle that when the Shadow vehicle proceeds down the hill or around the curve, the traffic has more opportunity to identify and respond in appropriate manner.

In mobile operations, when there is a shoulder, the TMA Operator of the Shadow Vehicle should consider being situated half way into the shoulder and half way in the same lane of the Trail Vehicle. This will allow the traffic to begin its proper movement into the desired lane as well as view the Trail Vehicle, in effort to avoid the operation.

e. MOBILE OPERATIONS

Rules for placements and movements of a TMA during a Mobile Operations are found the in the designated Traffic Control Plan.

During mobile operations, the TMA/protective vehicle is operated as any other vehicle, except its purpose is to be a protective or shadow vehicle. Keep the vehicle in gear and wheels moving forward. During a mobile operation the Operator is responsible for maintaining proper speed and position while providing the minimum required roll ahead distance as applicable to the designated Traffic Control Plan. Pay attention to hills, curves or other sight distance issues that may be present or cause the need to adjust the roll ahead distance to account for impediments.

Because a TMA’s purpose is to protect others form errant vehicles, the TMA should be and remain in proper position to accept the impact from the errant vehicle. If the TMA abandons the proper placement, then exposure to possible injury or damage become possible. The TMA Operator is responsible for keeping the TMA in position and placement to prevent injury or damage.

If the impact of an errant vehicle is imminent, consider all options including placing your head against the headrest and having both hand securely on the steering wheel to maintain focus and control of the TMA at all times.

During Mobile Operations, message/arrow boards are to be in proper mode with proper signage and/or arrow designation.

During Mobile Operations the TMA operator should maintain appropriate constant speeds and distances as required by the Traffic Control Plan.

Page of 14 41

The “Work Convoy” sign must be displayed on the TMA in mobile operations.

F. STATIONARY OPERATIONS

Rules for placement and movements of a TMA during Stationary Operations are found in the designated Traffic Control Plan.

During stationary operations, the TMA will be parked. When protecting the others during a Stationary Operation, the strobe lights must be activated, the message/arrow board working, and the TMA Scorpion must be fully deployed.

No vehicles or equipment are allowed in the roll ahead space or in the buffer space. The TMA shall be located in advance of the work area, but not in the buffer space. Refer to each individual Traffic Control Plan for spacing guidance and requirements.

The TMA front wheels should be turned away from the work crew/zone and when possible, should also be turned away from the work crew’s escape route and in direction that would not cause an accident.

TMA must be placed in neutral and the air brakes must be set during a Stationary Operation.

In most instances during a Stationary Operation, the TMA is unoccupied and is not occupied again until the work zone is being removed or ready for pickup. If the TMA Operator occupies the TMA during the operation, the TMA Operator shall be in position and in proper form and in a properly adjusted seatbelt to insure proper usage and safety.

During Stationary Operations, place Message board/arrow board in caution mode……not arrow mode.

G. ROLL AHEAD DISTANCE

Roll Ahead Distance differs for Stationary and Mobile operations. “Roll Ahead Distance” is basically the formula that is used to calculate the spacing requirements of where the TMA should be positioned in any particular operation pursuant to the proper Traffic Control Plan.

The chart and formula below provides some additional insight for the TMA Operator to consider when placing the TMA in either a Stationary or Moving operation. Although you are not required to calculate Roll Ahead Distances or spacing requirement of a TCP, you must comply with the rules and specifications, as contained in the applicable Traffic Control Plan and the TMA Operator should consider using the maximum distances. The Chart is a study performed by Texas A&M for TxDOT. A tractor and empty trailer weighs about 30,000 pounds. As demonstrated by the Chart, larger and

Page of 15 41

heavier vehicles are not contained on the Chart and information about roll ahead distance for heavier vehicles could be determined by the stated formula.

Another tip to consider when determining the stated TCP distance on the road during the operation is to “count stripes”. Stripes are 10 feet long. The distance between stripes is 30 feet. Therefore, there is 40 feet from the beginning of one strip to the beginning of another stripe. So divide the distance required and divide it by 40.

200 Feet is 5 stripes

150 Feet is 4 stripes

120 Feet is 3 stripes

100 Feet is 2.5 stripes.

30 Feet is less two strips (actually the space between two stripes (ie, the space between the end of one stripe and the beginning of another)).

As a general summary of most Traffic Control Plans a good practice for the TMA Operator to consider is:

Stationary TMA – 30 to 100 feet from Work Area.**

Mobile Operation Trail TMA – 120 to 200 feet from Work Vehicle.**

Mobile Operation Shadow Vehicle – 1500 feet from the Trail TMA.**

**However, each circumstance is different and a review and analysis of the Traffic Control Plan and situation should be made by the TMA Operator to insure the TMA is properly placed in the operation according to the applicable Traffic Control Plan.

The Traffic Control Plans are predesignated and found in Company Dispatch on Employee Assigned Email and if it is not there, the TMA Operator must notify the Supervisor in order that the correct Traffic Control Plan be made certain and the same data sent for everyone’s benefit and safety.

If you do not understand the Traffic Control Plan, call your Supervisor, Safety Officer, HR Manager or Call Center. You have the right to stop any operation if you do not believe the conditions are safe. Do not operate a TMA if you do not feel safe, comfortable, or do not understand the Traffic Control Plan or your duties.

ROLL AHEAD DISTANCES

Page of 18 41

H. REACTION TIME

In a mobile Operation, reaction time is important. If a TMA Operator notices an errant vehicle, he/she should consider safely alerting the others and then safely proceeding forward to lessen the impact, if possible.

NOTE: If a TMA Operator can drive forward to lessen the impact, then observation of all others should be made and then an attempt to maintain the minimum Roll Ahead Distance, as provided in the applicable Traffic Control Plan, between the TMA and the protected vehicle/zone. In instance where the recommended Roll Ahead Distance is not possible, consider refraining from rolling forward.

I. Employee Vehicle and Equipment Safety Review

All Employees must conduct Employee Vehicle and Equipment Safety Review (EVESR) of all vehicles and Equipment. This list is provided here in order that the TMA be aware and have access to this list as well as the other 2 lists in this TMA Guideline and Workshop.

i. Perform TMA Operation Guidelines - BEFORE EACH USE Checklist (found in the ”TMA Guidelines and Workshop” and the “Safety and Vehicle Policy)

ii. Perform the TMA and Scorpion Maintenance – BEFORE EACH USE Checklist (found in the “TMA Guidelines Workshop” and Safety and Vehicle Policy)

iii.Employee must verify he/she is equipped with all Personal Property and Equipment required for the Job Assignment:

i. Flagger Card

ii. Driver’s License, if applicable

iii.Hard Hat

iv. Vest

v. Steel Toed Boots or Steel Toed Shoes

vi.Pants

vii.Shirt with short or long sleeves

4. Employee must verify he/she has the proper amount of traffic control equipment and supplies present for the Job Assignment and in good working order:

i. Signs are clean and reflective

Page of 19 41

ii. Signs have flags on them

iii.Stands are locked when in deployed position

iv. Cones are clean and reflective;

v. Rumble Strips are in order in sets

viii.Key

If any item in the EVESR is missing or has an issue, contact your Supervisor and submit a Ticket to Fleet Manager. Make sure your Ticket provides a response that you are satisfied addresses your concern. If your matter does not receive timely attention, then send an “Human Resources Ticket” and a “Safety Officer Ticket”. At all times notify your Supervisor of all issues. If you do not understand how to submit a Ticket, call 844-ON ROADS 844-667-6237.

The other 2 checklists in the TMA Guidelines and Workshop are as follows:

(1) TMA Operational Guidelines – Before Each Use Checklist; and

(2) TMA and Scorpion Maintenance Intervals – Before Each Use Checklist

10.Understand and Accept.

Acceptance of Role, Responsibility and Risk. If you are assigned to be a TMA Operator, and you accept the assignment, then you are representing to Nixon Engineering that you are aware of all TMA guidelines and that you will comply with all rules and regulations in the use and operation of the TMA, and that you accept the role, responsibility, and risks associated with operating a TMA.

Page of 20 41

3. EQUIPMENT ISSUES In most cases when a TMA is required, employees are exposed to high volume and higher speed routes. A TMA is designed to absorb the energy of an errant vehicle. A TMA will increase your safety, offer additional protection to workers and the traveling public. Proper equipment should be used as appropriate.

A. SEAT BELTS & PPE (Personal Protective Equipment)

As a TMA Operator you must comply with wearing all the designated PPE while on location of job site. This includes your steel toe boots/shoes, safety vest, hard hat and seat belt.

Seat belt usage is mandatory in the state of Texas, as well as in any Nixon Engineering owned or leased vehicles. It is extremely important that the Operator of a TMA not only wear his/her seat belt, but also must have it adjusted properly.

Properly adjusted seat belts may minimize or reduce injuries. A seat belt should be secured in the manufacturer’s locking device and should be snug across the chest.

B. STORAGE OF EQUIPMENT

A clean vehicle supports personal safety. A TMA Operator is responsible for making sure that the cab of the truck is cleaned every day. Removing all trash and debris and securing all loose items will help prevent injury to the operator and/or others in the event of an impact.

Any loose items must be stored in the outside storage compartment, secured under the passenger seat, secured in the floor board of the passenger side of the TMA or secured with the passenger seatbelt.

NOTE: You may be required to store your lunch or other personal items in the cab of the truck. Make sure items are secured inside the cab and not placed on the dashboard, where they can become a projectile.

Do not place any items on seat in front of Message Board Touch Screen Units in the cab of the TMA, as such practice creates potential of the item to slide off and cause damage to the touch screen.

Page of 21 41

All drink containers must have lids. Only paper or Styrofoam drink containers are allowed in cab of vehicle, if not properly secured.

C. ENTERING/EXITING TRAFFIC and TURNING AROUND WITH A TMA

Make sure the attenuator is DOWN while executing a Traffic Control Plan

Make sure the attenuator is UP when not performing a Traffic Control Plan.

Be aware that you are driving a heavy and large vehicle. Related caution should be used.

Make wide turns and make sure the attenuator is UP when travelling.

When entering a lane of traffic the attenuator should be UP, the operator should consider reaching the traveling speed and then entering into the desired lane of traffic, when possible.

D. ALIGNING THE WHEELS

In a Stationary Operation, the wheels of the TMA should be turned away from the work zone, the air brake set, and the transmission placed into Neutral.

In a Mobil Operation, the TMA should be kept in gear and the wheels moving forward.

E. CHECKING MIRRORS

Use of mirrors allow the Operator to safely view what is happening behind the vehicle.

Auxiliary or convex mirrors give a larger field of view; however, awareness should be made that auxiliary or convex mirrors may distort the Operator’s perspective by making objects appear smaller and farther. Be aware that objects appearing in an auxiliary or convex mirror are actually larger or closer than they appear. TMA Operator should assess issues with mirrors to insure that operation of TMA is accomplished for the purposes intended.

IMPORTANT NOTE: As a TMA Operator, you should be aware of the activity going on in front of, to the sides, and behind you at all times. Continuously checking the mirrors will ensure your safety as well as they safety of your crew members, and the traveling public.

F. EMERGENCY PLANNING

Page of 22 41

Having an emergency plan and an escape route should be a priority each time you operate a TMA.

Some things to consider:

• Your exact location (using mile markers, exit ramps/numbers, direction you are traveling, city and county in which you are located)

• Who to call in event of impact or incident

• Name and contact data of Crew Leader, Supervisor, others on the Operation, and the Call Center.

• Is the scene safe or are you creating another hazard?

• Are incident/accident forms located within the TMA?

• Any other issues or concerns you deem appropriate and/or necessary

• You have a right to stop any traffic control operation if you believe an unsafe condition exists for yourself and/or others.

G. IF AN INCIDENT/ACCIDENT OCCURS

1. If and incident/accident occurs, consider the following:

• Emergency phone numbers

• Type of emergency services needed (EMT, Paramedic, Fire Dept, HazMat Crew, etc.)

• Call those on your Emergency Planning List, if an errant vehicles hits the TMA or anything else

• Your exact location (using mile markers, exit ramps/numbers, direction you are traveling, county in which you are located)

• Description of incident or traffic event

• Number of vehicles involved

• Complete all required Risk Management Forms

• Any other issues or concerns you deem appropriate and/or necessary

11.IF THE ATTENUATOR IS IMPACTED

Page of 23 41

Follow standard procedures in the “Safety and Vehicle Policy and Related Equipment”.

Best practice would include the following:

• Immediately report the event to your supervisor, authorities and all affected personnel in the work zone.

• Check to ensure all individuals, including those in the impacted vehicle, are safe and uninjured.

• If there are injuries, IMMEDIATELY SEEK MEDICAL ASSISTANCE.

• Do Not move the TMA unless DPS authorizes to do so. In all events a photo must be taken prior to any movement.

• When authorized to move the TMA and all vehicles away from traffic lanes to a secure location as soon as safely/legally feasible.

• Obtain a copy of the police report and case number and ensure that it notes the location as a work zone in the report.

• Get multiple pictures of all vehicles involved in the incident (too many is not enough) and license plates and other driver’s insurance card and driver license.

12.REMOVING A TMA FROM THE SCENE OF AN ACCIDENT

When preparing to remove a damaged TMA from the scene, consider the following:

• Is additional equipment needed to clean up the scene?

• Can the TMA cartridge be loaded onto a trailer or into the back of another truck bed, by a professional?

• Have professional Strap the TMA together using TxDOT approved slings/straps to secure the load.

IMPORTANT NOTE: Operators should use extreme caution when assisting or moving a compromised TMA out of the lane of traffic. The unit may not be adequately attached at the anchor points and should be inspected prior to moving. Loose or broken parts should be secured before the TMA is moved.

4. OPERATIONAL ISSSUES When the TMA is not on-route to a location or is not in use, it shall be parked in a well-lighted area, with all equipment secured properly.

A. TMA OPERATING GUIDELINES

Diesel fuel only.

Proper operation includes knowledge of how to care for and maintain adequate equipment function for travel and work zone safety. The TMA is a large, expensive piece of equipment that must be properly maintained and cared for to minimize down time and maximize work performance.

Refer to Traffic Control Plans and all Reference Materials and Operational Manuals.

The following items are guidelines to assist the TMA Operator in his/her endeavor to successfully drive and operate a TMA.

(1) MESSAGE BOARD TOUCH SCREEN UNIT

▪ Do not place items on the seat above the Touch Screen Unit

▪ Do not place items on the Touch Screen Unit

▪ Do not PUNCH the touch screen commands when setting and/or adjusting the touch screen. The touch screen is sensitive and it needs to be touched lightly.

▪ When cleaning the Touch Screen, dampen a cloth or paper towel with WATER ONLY, and gently wipe down, clearing any spots or loose dirt from screen and entire edges of unit.

▪ If the screen is not responding to a gentle touch, then calibration may be necessary. To calibrate the unit, power it off. Wait 10-15 seconds. Place entire hand in the center of the touch screen, with palm down. Hold your palm down while powering back ON. After a few seconds, a message will appear that states “to calibrate unit, release now”. Then lift palm off the touch screen. Touch the cross hairs directly in the center of the screen and as they appear (the order will be clockwise: Upper Left, Upper Right, Lower Right, Lower Left and Center). This process may need to be performed more than once.

▪ The lights on the Message Board can be an issue and at times needs to brightened or dimmed depending on daytime, night time or weather conditions. Also try the following: Login to the touch

Page of 25 41

screen, select “settings”, select “pixels override”, choose “Menu”, choose the 700 for bright and 1200 for dim.

(2) TIRE AIR PRESSURE and WHEEL SAFETY

• On original tires all the way around the TMA air pressure should be kept at 115 psi. This information can be found on the cab of the truck, inside the driver door, next to the seatbelt (where it attaches inside the cab of the TMA).

▪ Check all lug nuts to insure that all are present and are not loose.

(3) AIR TANK FOR AIR BRAKES

• The Air Tank is located underneath the center of the bed of the Host Unit of the TMA.

• There are 3 pull cords on this Air Tank and they represent three separate sections of the Air Tank: Wet, Primary & Secondary Air Tanks.

• Once a week (on every Thursday), all three Air Tank Sections should be drained of all air by pulling on each of all three “Pull Cords” until the “hissing” of releasing air stops.

• The air pressure for the braking system will rebuild the next time the unit is started.

• Draining all air from all 3 “Pull Cords” prevents moisture build up in the air tank and help prevents rust, corrosion, and freezing.

(4) FLUIDS CHECK

• There are 4 main fluids to check daily and weekly on your TMA (i.e. washer fluid, coolant, oil & power steering fluid).

• Unfasten the hood on both Driver and Passenger sides and pull forward.

• Windshield Washer fluid is blue and located on the passenger side at knee level.

• This is provided by Nixon Engineering and can be obtained from your supervisor from Fleet Manager.

• Coolant is orange and located on the passenger side at head level.

• This is a Nitrite Free coolant and is safe for Aluminum components.

Page of 26 41

• This level should not fluctuate and if it does-report immediately to your supervisor and Fleet Manager. A substantial drop in coolant indicates a leak of some kind in most cases.

• Power Steering Fluid is located on the driver side, at approximately chest level.

• It is a generic automatic fluid and should only be checked while the TMA is running (same goes for checking the Transmission Fluid).

• Fluctuation of power steering fluid is to be expected, but only between minimum and maximum lines. It should never drop below the minimum line. If it does then contact your supervisor to contact Fleet Manager Immediately.

(5) REGEN (Regeneration)

• Regen is designed to burn off the excess exhaust buildup.

• If you idle for long periods of time without accelerating the RPMs, the unit may require you to regen more often.

• There is a sticker on the driver side sun visor that indicates information on when the unit is telling you to regen.

• The unit will not regen unless it needs to, YOU CANNOT FORCE A REGEN.

• The unit will indicate a regen is necessary with dash lights in Amber.

• If you ignore these lights for too long, the unit will become sluggish and eventually not work at all.

• The regen button is located just below the air brake release knob and right beside the scorpion raise/lower control.

• When the unit indicates a regen is necessary, press the regen button upwards and hold for approximately 5 seconds, then release.

• A regen takes anywhere from 30 minutes to 1 hour, depending on age of unit.

• Once you have completed a regen, you must let the unit idle for approximately 15 minutes to cool the exhaust down; as a regen creates ample amount of heat and can damage other components if unit is not cooled properly.

• You may up the RPMs (as you do when idling for long periods of time) to speed up this process of cooling

• Check oil, pull dipstick before starting the engine, make sure it is at “safe line”. If vehicle needs oil contact Fleet Manager.

Page of 27 41

(6) BEFORE EACH USE – Checklist (Operational TMA Guidelines) (See Also Exhibit B):

• Check the tire pressure and lug nuts.

• Walk around the unit, inspecting for loose or missing bolts, pins and safety snaps.

• Inspect for cracks in the energy absorbing modules, welds and steel structure.

• Inspect all lights for proper operation (includes arrow/message board if attached).

• Cycle the unit from stowed to deployed (see next Sections) and back to stowed position, ensuring proper sequence and function (including arrow/message board lift system if attached) pay close attention for any binding or “slop” during operation and that the alarm is functioning properly.

• Power ON the Charger for the Message Batteries, which is located to the right of the Scorpion Control Box in the cab. Keep the power ON for one hour on TMA Units Numbered 201-230.

• Cycle the Touch Screen

o Power it to ON

o once it loads, tap “Log In”

o then choose the message

o verify the chosen message is actually displaying on the Message Board/Arrow Board.

• On TMA Units 231 and Up: Power on the Arrowboard and check lighting functionality to insure all bulbs are in working order (See Also Exhibit D).

• Check height of TMA in deployed position to ensure it is in specification (13 inches)

• Any deficiencies should be corrected before use.

• REFER TO ANOTHER LIST AND ACCOMPLISH IT: See Also the “TMA & Scorpion Maintenance Interval Checklist – Before Use”, which also must be performed before each use. (See Also Exhibit C).

• REFER TO ANOTHER LIST AND ACCOMPLISH IT: See also the “Employee Vehicle and Equipment Safety Review” (EVESR), which also must be performed before each use. (See Also Exhibit A which is also referenced in the Employee Handbook and the Accident Prevention Plan and the Safety and Vehicle Policy.)

Page of 28 41

(7) TO RAISE (“STOW”) THE UNIT FOR TRANSPORT

• Ensure that both the truck bed and area above the rear of the host vehicle is clear of any tall equipment, in order that Scorpion is not bound or compromised.

• Locate the desired control box, either the in-cab controller (if installed) or the plug in. If using the plug-in, and it is not already plugged in, plug it into the socket on the TMA near the rear passenger side of the truck-directly behind the license plate.

• Push the “UP” button on the chosen controller and hold until the unit makes contact with the support posts. IMPORTANT: IF AN ARROW/MESSAGE BOARD LIFT SYSTEM IN INSTALLED, BE SURE IT CYCLES TO THE DOWN POSITION BEFORE THE TMA RAISES.

• CONTINUE to hold the UP button until the scorpion slides forward 1-2 inches on the support post cradle. This ensures the hydraulic system is holding the TMA tight against the cradle and will save wear and tear on the unit.

• If using the plug in controller, unplug and store in the cab

• See also Traffix Scorpion Truck Mounted Attenuator Specifications.

(8) TO LOWER (“DEPLOY”) THE UNIT FOR USE

• Ensure that both the area above and to the rear of the host vehicle is clear.

• Locate the “in-cab” controller.

• Push the “DOWN” button until the TMA is fully unfolded and the rear box has stopped moving and the tail/ICC light covers have deployed

• CONTINUE to hold the DOWN button until the Arrow/Message board lift system (if attached) has fully raised, or for 1-2 more seconds if there is no lift system. This will ensure the TMA is fully deployed and the hydraulic system is holding it in the proper position.

• Make sure the Arrow/Message Board is displaying the proper message.

• See also Traffix Scorpion Truck Mounted Attenuator Specifications.

9. LIGHTING ON TMA

A. Day Time

Page of 29 41

a. Headlight, Strobe Lights and Arrow/Message Boards are to be ON.

b. Arrow/Message Boards must be in “Bright” mode in order to be more visible to traveling public.

B. Night Time

1. TMA Operators must ensure that all lighting has been dimmed according to the MUTCD or TxDOT specifications for nighttime activities.

2. The TMA Operator is responsible for ensuring:

• Clear and Simple messages are provided to the traveling public via message boards.

• All signs are retroreflective and in operational condition.

• Adequate roll ahead distance is provided according to designated Traffic Control Plan.

10.FLASHING ARROW PANELS

Flashing arrow panels are temporary traffic control devices that provide warning and directional information to assist drivers through or around a temporary traffic control zone.

Flashing arrow panels may be operated in one of three operating modes:

• Left/Right Arrow

• Double Arrow

• 4 Corner CAUTION

The Left/Right Arrow mode is used when traffic has no choice but to go left of right.

The double arrow mode is used when traffic has a choice to go right or left.

The Left/Right Arrow and Double arrow modes are used for stationary or moving lane closures on multi-lane highways.

The caution mode is used for shoulder work, blocking the shoulder, work within a lane when the lane is not closed, and lane closures on two-lanes, undivided highways. When used during night operations, these displays shall be dimmed by 50 percent (if applicable).

Page of 30 41

When closing multiple lanes, a separate unit shall be used to close each lane.

IMPORTANT NOTE: THE FLASHING ARROW PANEL SHOULD BE IN THE CAUTION MODE UNTIL THE TMA HAS REACHED ITS DESIRED LOCATION OR LANE. ONCE THE TMA HAS REACHED THE DESIRED LANE, THE DIRECTIONAL ARROW SHOULB BE DISPLAYED.

For moving lane closures on two-lane, undivided highways, the panel shall be deployed within the lane to be closed.

When an interior lane is being closed by itself, 2 units shall be deployed within the lane to be closed. When closing multiple lanes, a separate unit shall be used to close each lane.

IMPORTANT NOTE: WHEN DEPLOYED, THE PANEL SHALL BE SIGHTED AND ALIGNED WITH APPROACHING TRAFFIC TO ENSURE VISIBILITY OF THE DISPLAY.

11.Idle

TMA should be turned off in Stationary Operations. It is not good practice to idle TMA units for long periods of time. When the unit idles for long periods of time the engine is flooded with fuel and can cause problems within the exhaust system, over time. In addition, the Message/Arrow Board has an independent battery(s). The strobe lights have potential to drain the vehicle battery and a good practice is to restart the vehicle and let it run for about 5 minutes every two hours.

In the event the Operation requires the TMA to idle (and you do not have the option to turn off the TMA), then you must flip the accelerator for cruise control switch to the up position until the unit idles between 900-1200 RPMs. This allows the unit to be rushed with air and balances out the flooding of fuel and burns off the excess. Once the unit has been idled up into the 900-1200 RPM area, you must tap the cruise control button to off to lower the RPMs and then can turn it back on. The TMA will not or should not engage into gear with the RPMs running high like this. IT IS RECOMMENDED THAT YOU NOT RAISE OR LOWER THE SCORPION OR ARROW/MESSAGE BOARD WHILE RPM’S ARE RAISED AT THIS LEVEL.

In mobile operation, when traveling slow speeds, put the TMA in low or second gear. This should raise the RPM to the 900-1200 RPM

12.Weather Conditions

Page of 31 41

a. During or after any rain, do not leave the pavement. The TMA is heavy and is susceptible to sinking into the ground and getting stuck in the ground.

b. Take proper and extra precautions in all adverse weather conditions as appropriate.

13.Other Ideas and Concepts

a. Driving under Overpasses

i. Make sure attenuator is completely raised before proceeding under any overpass. Failure to raise completely has potential to hit the overpass and cause damage.

ii. Make sure attenuator is completely raised when appropriate.

b. Make Wide Turns

c. Back Up Carefully

d. When Turning, Stop and Raise Attenuator

5. TMA MAINTENANCE INTERVALS

A. TMA & SCORPION MAINTENANCE INTERVALS

(1) BEFORE EACH USE (Maintenance Interval Guidelines) – TMA Operator Responsibility

• Check Tire Pressure and Lug Nuts

• Walk around the unit inspecting for loose or missing bolts, pins and safety snaps.

• Inspect for damage to the energy absorbing modules and aluminum and steal structure.

• Inspect ALL lights for proper operation (including strobes, blinkers, headlights, tail lights, hazard lights and arrow/message board)

• Check the height of the entire attenuator from the ground up to the bottom of the attenuator while in deployed position, to ensure there is a space that measures 11 to 13 inches between the ground and the bottom of the attenuator

Page of 32 41

• Cycle the attenuator (from stowed to deployed and back to stowed again) to insure the attenuator raises and lowers properly. Pay close attention for any binding or loose connections or any noises such as screeching or squeaks or other awkward events. (see also Traffix Scorpion Truck Mounted Attenuator Specifications).

• Arrow board. Test the arrow board by making it partially raise and lower. Turn on the lights to insure the arrows and/or the caution message works. (see also Wanco Manual)

• Message board. Test the message board by raising and lowering the board. Be certain that once the unit is fully in the upright or down position, the control switch is turned back to the center of the control box. DO NOT LEAVE THE SWITCH IN THE UP OR DOWN POSITION, AS THIS WILL DAMAGE THE ACTUATOR OF THE MESSAGE BOARD AND CAUSE PROBLEMS AND EXPENSE. (see also Solar Tech Manual).

• Ensure that retro-reflective sheeting is in place and meeting requirements for job.

• Any deficiencies should be corrected before use and notification to the Fleet Manager and Supervisor is required.

• REFER TO ANOTHER LIST AND ACCOMPLISH IT: See Also the “Operational TMA Guidelines Check List – Before Use”, which also must be performed before each use. (See Also Exhibit B)

• REFER TO ANOTHER LIST AND ACCOMPLISH IT: See also the “Employee Vehicle and Equipment Safety Review”, which also must be performed before each use. (See Also Exhibit A, also referenced in Employee Handbook, Accident Prevention Plan and Safety and Vehicle Policy)

• See Also Exhibit C, “Scorpion Truck Mounted Attenuator Maintenance Intervals” Before Each Use

(2) MONTHLY (IN ADDITION TO ABOVE) – Supervisor Responsibility

• Check hydraulic fluid level and top off if needed (red transmission fluid).

• Use wrench to check fasteners for tightness.

• Check and apply grease, as needed, to all grease fittings.

• Visually inspect structural components for corrosion and cracking

• Ensure that electrical connections are corrosion free, all lights are securely attached and functioning correctly, and that covers for rear ICC light bar and rear tail lights are securely attached and functioning properly

• Correct any deficiencies.

Page of 33 41

• Test batteries associated with Arrow/Message boards with and without load (test with battery tester Nixon Engineering provided) to insure they carry 6 Volts Each.

• Check the Battery water levels and fill with distilled water to appropriate level.

• Test the alarms to confirm any are functioning properly.

• See Also Exhibit C, “Scorpion Truck Mounted Attenuator Maintenance Intervals” Before Each Use and Monthly

(3) ANNUALLY – Designated Repair Facility

a. Annually Inspection of Attenuator

• Drain the Hydraulic reservoir and re-fill with new red transmission fluid (see install manual for capacity/type).

• Inspect all hinges and pivot points for wear and correct as needed.

• Disconnect, clean (as required) and reconnect all electrical contact points.

• Inspect for rust on painted structure, prep surface, and reapply paint as required.

• Galvanized sections should not be sanded if corroded or scratched, but should be touched up with the proper coating. PLEASE NOTE: if exposed to harsh environments on a regular basis, galvanized finish will hold up better than painted finish and should be considered as an option

• Nixon Engineering TMAs are inspected and recertified annually by a Scorpion Certified Attenuator Maintenance and Repair Facility. Any repair or deficiencies are certified on behalf of Traffix Devices Inc. that the Scorpion is in an “AS MANUFACTURED CONDITION”.

• See Also Exhibit C, “Scorpion Truck Mounted Attenuator Maintenance Intervals” Before Each Use, in its entirety

b., As needed and appropriate

▪ TMA Operator must insure the TMA is thoroughly washed including the undercarriage, after the TMA is used on any operations that are related to snow, sleet or ice conditions. The chemicals used to during these types of operations cause rust and corrosion to electrical components.

Page of 34 41

▪ The above intervals should be modified if the Scorpion is being used in severe service applications. These include, but are not limited to, applications which include long periods of usage on rough roads and/or rumble strips, longer daily service hours, extremes in weather, higher speed (above 30 MPH) usage while deployed/being deployed, or exposure to corrosive materials (i.e. salt spreading). TMA Operator must notify “Fleet Manager” of any such activity that warrants modification of Maintenance Intervals.

B. The Actual Vehicle (Freightliner and Hino)

▪ Fleet Manager sends Maintenance Reports every week for all Vehicle Maintenance Intervals to Supervisors.

▪ Nixon Engineering Maintenance Procedures include the TMA Operators cooperating and assisting the Supervisors and Fleet Manager in transporting the TMA to the authorized Maintenance Facility to receive proper Maintenance. Drive time is paid for such assistance.

▪ Repairs are managed on the same procedure as Maintenance.

▪ Department of Transportation inspection is performed annually and the procedure is the same as for Maintenance.

6. TMA OPERATOR’S RIGHT
