Drive very slowly
Personal Safety
Wear safety glasses at all times when in the shop area
Ask when not sure of any procedure
Wear non slip oil resistant soled leather shoes
Clean any spills immediately!do not Mop up antifreeze or oil – use absorbent pads
( “Pig – Mat” )

Do not wear contact lenses
Do not hesitate to remove yourself from any unsafe environment
Understand the health risks of any chemicals that you are using
Personal safety practices
Do not work when intoxicated or taking medications that reduce your alertness
Do not attempt to lift any heavy object without the proper tools or assistance
Personal Safety
Do not work alone
Insure an instructor is present in the lab while you are working on any project.
Safety when Lifting a Vehicle
Use appropriate lift pointsLook them up or ask if not sure of vehicle lifting points
Insure any Air Springs are disabled or supportedThis avoids ruining Air Springs when lowering vehicle
Support raised vehicle with jack‐stands… Use jack‐stands in pairs
… Or Lower vehicle to the safety latches on the lift.
Safety when Lifting a Vehicle
Individual who is operating the jack or hoist will be the one to set the jack stands in place.
Shake vehicle, After wheels are off the ground, to insure it is properly supported.
It is better to have a vehicle fall from the lift when it is close to the ground!
Personal and Vehicle Safety
Removing Large tires wheels will cause back injury
Back strain may not be noticed until you are older!
Use a wheel dolly or use a prybar with tire close to the ground when removing large tires
Do not allow tires to bounce off the shop floor(may bounce into another vehicle)
Brake Dust and your Health
Brake dust is especially hazardous to breath
Can cause serious lung disease that will not develop for many years into the future
Always contain the dust with an approved brake vacuum or brake washing station
Brake Inspection Safety
Wash brakes with approved cleaner BEFOREdisassembly to keep brake dust out of the Air
Keep grease & oil from brake liningsOily fingers or oily brake washing fluid contacting brake pads
will cause squeak, grab, or pull when stopping the vehicle. Customers do not appreciate this!
Wash hands immediately after handling brake parts…. or wear gloves.Gloves will protect your hands from harmful oils and chemicalsused in many vehicle maintenance and repair procedures
Personal – Vehicle – Equipment Safety
Before using any new tool or piece of equipment…Read the instructions and/or service procedures
Ask questions
DO NOT use any new tool or equipment in the automotive lab at Linn‐Benton
Community College until you have been checked out by an instructor
Professional Safety
Do Not falsify any data on work ordersor inspection sheets
If you did not inspect the part closely…. …….DO NOT indicate it is O.K.
If you are not sure how to inspect a component……ASK Questions!
You will lean and become more competent
Professional SafetyDo Not falsify any data on work ordersor inspection sheetsBe accurate when recording the VIN number
Do not guess the vehicle mileage – If you did not actually see the mileage – leave it blank!
Do not record measurements unless you actually measured it! …. Say “looks good” or “Marginal” instead of “5/16” or “8mm” unless you measured it
Brake Inspection Safety
Use ONLY the specified Brake FluidMost systems use DOT‐3
Some brake systems will become unsafe if DOT‐3 is used!
Master cylinder cover may indicate specified fluid
Clean around the master cylinder before removal
Clean around any brake fittings before removing a brake line or hydraulic component.
Cover or Plug any open brake line or component.
DOT‐3 and DOT‐4 Brake Fluiddissolves paints and sealers!
Wiping up spilled brake fluid will damage….… Vehicle paint and finish… Vehicle lifts… Sealed shop floors… Vehicle Steering wheels and controls
If you do not wash hands after wiping up spills
It takes time for fluid to dissolve paint….….damage will not show for many days. Wash spills using lots of water to safely removeBrake Fluid after any spill or drip
Vehicle Safety with Fluids
Ensure proper fluid level. Over or Under Fill is BAD
How do you check proper fluid level? ….…. at Operating Temperature?…. at Room Temperature?…. Engine Running or Turned Off?
Look Up procedure to check fluid level
Vehicle Safety with FluidsLook Up proper fluid type.
Mixing in aftermarket antifreeze can ruin the cooling system
Use Only Manufacturer specific fluids/oils
Do Not allow dirt to enter ANY hydraulic system.Clean area BEFORE opening any hydraulic system.
Plug open hydraulic lines‐fittings to prevent any dirt or grit from entering the system.
Environmental Safety with FluidsDrain ‐ Store Fluids in approved container.
Antifreeze ‐ Coolant goes in GREEN catch‐drain
Motor oil ‐ Transmission Fluid in BLACK catch‐drain
other shops may have different typeor color containers
Environmental Safety with FluidsGasoline goes into Red Gas–Caddy and returned to original vehicle’s gas tank – or Waste Gas storage drum (ask Matt)
Gasoline Filters DO NOT go in trash
Collect with oil filters
Spilled Fluid SafetyClean Spills immediately!
DO NOT use the Mop to clean oils or coolants!
Use absorbent spill pads called “Pig‐Mat”
Environmental Safety with FluidsDO NOT MIX RECOVERED FLUIDS
Any Brake Cleaners must stay out of used oilOil and Coolants must be kept separateGasoline must not be mixed into oil or coolantOil filters (any type) should be crushed to recover oilsBrake Fluid collected separate from all other fluidsUse Pig‐Mats to clean spills
DO NOT toss Pig‐Mat into trash!
Removing a suspension part
Springs may let go with explosive force
Heavy axles may fall
Components can move farther than they are designed to move.
Electric wires may be ripped out.
Hydraulic lines will be damaged and bent
Hoses may get pulled off
Removing a suspension part
Make Sure Spring Tension is removed or contained BEFORE bolts are removed.
Read Procedures – Ask if not Sure
Look for wires – hoses – lines that may get stretched
Safety for your Eyes

A/C Refrigerant
Air Conditioning systems use refrigerant to move heat from air inside the car to air outside the car
Refrigerants are HAZARDOUS to you and the environment
Refrigerant ‐ Personal Safety
A/C Refrigerant is under high pressure even when the engine is turned OFF.
Removing any Air Conditioner fitting or component can allow liquid refrigerant to spray out.
Liquid refrigerant spraying out from any fitting will instantly freeze your skin or eyes.
Escaping refrigerant will cause instant frostbite to skin and can blind you if it contacts your eyes!
Motor Vehicle Air Conditioning (MVAC) refrigerants must be recovered/recycled to protect the environment.
MVAC refrigerant MUST NOT BE RELEASED into the atmosphere.
Service facilities not having approved recovery and recycling equipment are not permitted to perform any refrigeration service work.
Technicians working with MVAC must be EPA certified
Refrigerant – Environmental Safety
MVAC refrigerants must be properly discharged into a refrigerant recovery unit BEFORE components or refrigerant lines get disconnected.Any technician discharging refrigerant must successfully
complete EPA approved training.
LBCC Automotive students participate in the ASE Refrigerant Recovery and Recycling ProgramIf you pass the test you can legally work with
Motor Vehicle Air Conditioning (MVAC) refrigerants
EPA Approved Training
#1 Safety Rule
Ask questions when you are not sure.
