5. PROCEDURES

5.1 General

Hand tools are those tools for which the hand provides the motive force, e.g.,

picks, shovels, axes, crowbars, wrenches, saws, chisels, hammers, screwdrivers,

etc. It is the contractor's duty to ensure that his workmen are properly instructed

in the selection and use of the correct tool for the job. Tools constructed of good

quality materials should always be used. Poor quality tools increase the risk of

accidents and also reduce the efficiency of work.

Power tools, however, allow many jobs to be carried out more efficiently and

with greater speed and accuracy. The correct use of power tools can only be

achieved by the proper training of workmen, by proper maintenance, and by

adequate site supervision. Many accidents have occurred because unskilled and

untrained labor have been allowed to operate power tools in an incorrect manner.

The majority of accidents involving tools are caused by incorrect usage, improper

handling or poor maintenance. The basic rules for the prevention of accidents

involving tools are:

• The correct tools must always be used for the job.

• All tools must be kept clean and protected against corrosion and damage.

Inspection and maintenance must be carried out systematically and at regular

intervals.

• All damaged or worn tools must be promptly and correctly repaired.

• An efficient storage and accounting system must be operated.

• Each tool will be given a unique validation sticker to confirm that it has

been inspected and tested. Contractors equipment must undergo the same

testing and inspection prior to being allowed and used offshore.

• Work areas must be kept clean and tidy. Good housekeeping is essential to

safety.



• Only very low voltage (48 volt or less) power tools are permitted to be used

inside metallic equipment (vessel, column, tanks, etc.), otherwise air driven /

pneumatic tools are to be used.

• Work using power tool inside hazardous zone must be covered with a hot

work permit.

5.2 Hand Tools, General

5.2.1 Quality

The contractor shall ensure that the finest quality tools shall be provided for

all jobs where hand tools are used.

5.2.2 Cleanliness

The contractor shall ensure that hand tools are regularly cleaned and, where

necessary, lightly oiled as a protection against corrosion.

5.2.3 Repair and Storage

All hand tools shall be regularly inspected before and after use, and before

storage. If wear or damage is observed, the tool should be withdrawn from

use for repair or disposal. The contractor shall ensure that the storekeeper

maintains a record of all tools issued, repaired, and withdrawn from use.

Proper racks and boxes shall be provided for the storage of hand tools.

5.2.4 Selection

The majority of accidents are caused by using an incorrect tool for the job.

It is essential that the correct type, size, and weight of tool should be decided

upon before any work is carried out.

5.2.5 Electrical Risks

All un-insulated metal tools are conductors of electricity. Where work takes

place on or near electrical operations, only properly insulated and non-

conductive tools should be used. Insulation should be checked at regular

intervals by a competent electrician.



5.3 Individual Hand Tools, Precautions

5.3.1 Screwdrivers

It is essential that a screwdriver has the correct size of tip to fit the slot of

the screw. If the screwdriver fits the screw correctly, the screw will be

drawn into the correct position without unnecessary force being applied.

Over-tightening of screws can lead to possible hand injury if the screwdriver

slips.

Screwdriver shanks are not designed to withstand the twisting strain applied

by a pair of pliers or more grips in order to obtain additional leverage. On

no account should screwdriver handles be subjected to blows from a

hammer or similar instrument.

Screwdrivers should never be carried in the pockets of coveralls or other

clothing. A screwdriver can produce a serious wound.

5.3.2 Hammer

It is essential that the right kind of hammer be selected for the job. Hammer

handles should be made from smooth timber or be made of an integral head

and shaft of steel. Hammer heads should be secured to wooden handles with

proper wedges.

5.3.3 Chisels

Cutting edges should be kept sharp at all times, and the original shape and

angle should be maintained. Re-sharpened cold chisels should be suitably

hardened and tempered to maintain them in a safe working condition. The

chisel heads will mushroom in use. As soon as mushrooming is observed,

the head should be reground with a slight taper around the edge to prevent

chipping and reduce the tendency to re-mushroom. Eye protection should be

worn at all times when a cold chisel is used.

On jobs where it is necessary to use a sledge hammer for striking the chisel,

the chisel should be held by a second person using a pair of tongs.

Wood chisels should also be maintained in a sharp condition so that

minimum pressure is exerted when making a cut. If the chisel is to be

struck, only a wooden or soft mallet should be used.



5.3.4 Picks and Shovels

Picks and shovels shall be maintained in a serviceable condition at all times.

Shovel blades should not be allowed to become blunt, turned, split, or

jagged. Pick head points should be kept sharp and heat-treated so that the

metal wears down in use and does not splinter or chip off. Shafts of picks

and shovels should be kept free from cracks and splinters.

5.3.5 Spanners and Wrenches

Only spanners and adjustable wrenches of the right size should be used.

When possible, use box-end rather than adjustable wrenches. The jaw

should first be checked for any sign of opening out or splitting. Spanner and

wrench lengths are graded to provide sufficient leverage on the nuts for

which they are designed. Improvised extension to these tools is an unsafe

practice and may cause the bolt tread to strip or cause shearing of the bolt.

On no account should ordinary wrenches be struck by a hammer when

tightening nuts. For heavy work of this nature, a properly designed slugging

wrench should be used.

5.3.6 Pipe Wrenches

Pipe wrenches must be large enough for the job, the jaw teeth must be kept

clean and sharp, and the knurl, pin, and spring should be kept free from

damage. Pipe wrenches should never be struck with a hammer, nor should

they be used as a hammer.

5.3.7 Pliers

Pliers should only be used when there are no other tools for the job. They

are meant only for gripping around objects and should not be used as a

wrench.

Care should be taken when cutting soft metal with pliers to ensure the scrap

portion does not fly off and cause injury. If wire is cut under tension, then

long handled pliers should be used. Where pliers are used for electrical

work, they must be fitted with insulated handles. All pliers should be kept

free from dirt and grit, and the movable parts should be lightly lubricated.

5.3.8 Jacks

Jacks should be marked with rated capacity and must be heavy enough and

strong enough to raise and maintain the load. They should be placed on a

firm and solid support, and the load should be positioned on the center line

of the jack.



Once a load has been raised, it must be shored or blocked. The jack should

never be relied upon to hold the raised load in position by itself. Extreme

care should be taken when working under or near a raised load.

5.3.9 Hacksaws

The correct type of blade should be selected to suit the material to be cut.

The blade should be set in a hacksaw frame so that the teeth are pointing in

the forward direction, and sufficient tension should be applied to ensure

blade is maintained rigid.

5.3.10 Hand saws

Many kinds of woodworking hand saws are available, and care should be

taken to select the correct saw. All hand saws shall be regularly examined to

ensure that the saw teeth are properly set so as to avoid binding in the timber

which can cause the blade to buckle. The teeth should be kept sharp, clean,

and lightly oiled. When the saw is not in use, the blade should be protected

by a slotted piece of timber or a sheath.

Two-man saws should be operated by pulling only. The cut should be kept

straight to avoid the blade buckling. The cut should be wedged open to

prevent the timber from pinching the blade.

5.3.11 precautions

The care and safe use of manual tools such as hammers, cold chisels,

punches, files, and spanners, screwdrivers and pliers includes:

• Tools must be kept clean and free from corrosion.

• Ensure all moving parts are free to slide or rotate as required.

• Ensure all cutting edges are kept sharp.

• Ensure all burrs are removed from the edges of tools.

• Tools not in use must be stored safely as follows:

– Tools must be stored in suitable boxes or containers, or hung on

racks.

– Cutting edges must be protected.

– Tools must be placed where they cannot roll or fall off benches.

– Heavy tools must be placed where they do not cause an obstruction.

• Always use the correct tool for the job.

• All handles must be securely fitted to tools.

• Suitable eye protection must be worn.



• Most hand tools, unless specifically designed for electrical use, are

conductors of electricity, therefore extreme caution must be exercised

when working near electrical equipment.

• Insulated and non-conducting tools must be tested regularly by a

competent person.

• Steel tools that have previously been used on light alloys must have all

traces of alloy removed before being used again on steel equipment.

• Before using any type of hand tools on metallic equipment in a

hazardous area, the area must be certified as Gas Free. Where it is not

possible to gas free the area, then other arrangements must be made.

• When using non-sparking tools mitigate the effects of mushrooming by

re-shaping or replacing.

WARNING

NO TOOLS MAY BE REGARDED AS NON-SPARKING. REDUCED-

SPARKING TOOLS MUST BE USED WHEN IT IS ESSENTIAL THAT

WORK BE CARRIED OUT IN POTENTIALLY EXPLOSIVE

CONDITIONS.

5.4 Power Tools, General

5.4.1 Quality

The operator shall ensure that all portable power tools do not exceed 125

volts rating, are manufactured of sound materials, and are free from defects

and properly grounded.

5.4 .2 Repair and Storage

All portable power tools shall be stored in clean, dry conditions. The

contractor shall provide a schedule of systematic inspection and

maintenance for all power tools. All tools shall be returned to the

storekeeper at the completion of each individual job. Power tools must not

be left lying around the job site where they could be damaged.

Rotating tools should be switched off and held until rotation has completely

stopped before they are set down. Tools must be disconnected before

changing bits, blades, cutters, or wheels.

Power for tools can be supplied by compressed air, explosive cartridge, or

electricity. All portable power tools must be equipped with properly

functioning "dead man" switches.



5.5 Electrically Operated Tools

5.5.1 General

All electrically operated hand tools shall be rated and used at a voltage not

exceeding 125V to ground.

Before any electrical tool is used, a careful check shall be made by the

supervisor to ensure that the supply voltage is within the range marked on

the information plate on the tool. Ground Fault Circuit Interrupters (GFCIs)

are required for all 120 volt, single phase, 15 and 20 ampere receptacle

outlets on construction sites which are not a part of the permanent wiring

system.

All electrical power hand tools shall be of the double insulated type or

properly grounded.

External metal parts of double insulated tools (drill chucks, saw blades, etc.)

are insulated from the electrified parts inside the tool and, under normal

conditions, contact with electrified parts of the tool does not take place.

However, under wet conditions, rain, condensation, high humidity, damp

locations, etc., the hazards are as great as with faulty grounded tools. All

electrical tools are hazardous when used damp or wet, but with double

insulated tools the moisture coupled with metal dust, carbon dust, etc. can

form a conductive path from inside the tool to the surface through the

ventilation holes or cracks. Since there is no ground wire to carry this

current away, the user can receive an electric shock. Double insulated tools,

like all electric tools, must be kept dry and should not be used without a

ground fault circuit interrupter.

All tools shall be used with extension cords which are as short as possible.

All extension cords shall be fitted with grounding pin and blades to fit the

socket outlet on the distribution board. Extension cords shall be of the

three-wire conductor type. Plugs and sockets must meet the National

Electrical Code requirement with respect to grounding and polarity.

Over current protection shall be provided to extension cords in accordance

with the requirements of the National Electrical Code Article 240. Factors

to be considered for adequate over current protection are: type of

conductors, size, and length of run.

Example: Consider electrical equipment being used on a construction site

that may require 15 or 18 ampere (amp.) capacity. Construction plans call

for three No. 12 AWG (wire size) copper conductors which run to a 20 amp.

receptacle (120 v) 40 feet from the electrical panel box. This circuit is



protected by a 20 amp. circuit breaker. Is this a problem? Yes - There may

be three problems: (1) the size of the conductors, (2) the length of cable run

and, (3) the circuit breaker size.

In order to prevent an employee from receiving an electric shock, the

breaker size and receptacle should be reduced to 15 amp. or the conductors

changed to a No. 10 AWG so that the breaker can function at 20 amp. when

required. Leaving the circuit the way it is would allow considerable

electrical leakage without tripping the circuit breaker. Also conductor

insulation would be subject to heat damage causing electrical leakage and

fire. Heavy duty construction type extension cords are required for 20

ampere circuits, No. 14 AWG or larger size for 100 feet of run length. (See

Figure 6.)

Where it is necessary to make electrical splices, these shall be made with

proper connector blocks or by plug and socket connectors. Taped joints

shall not be permitted.

5.5.2 Maintenance and Storage

A proper inspection and maintenance routine shall be established by the

personnel for all electrical tools. The inspection and maintenance of all

tools shall be carried out at least once in every working week by a competent

electrician.

All tools shall be stored in a clean, dry place, and a record of issue and

receipt shall be maintained by the storekeeper.

5.5.3 Personal Protective Equipment

Personnel shall ensure that all operators are provided with eye, head, and

ear protection. If there is any likelihood of harmful dust being emitted, dust

respirators should be used.

5.5.4 Individual Tools, Precautions

5.5.4.1 Grinders

All grinders shall be equipped with a protective guard which allows only the

working part of the wheel to be exposed. This guard must not be removed.

Grinders shall be clearly marked with their maximum running speed. The

maximum running speed of the spindle must not exceed the maximum

periphery speed marked on the grinding wheel. Wheels should be checked

for defects before mounting. All defective wheels must be destroyed. (See

Figure 5.)



5.5.4.2 Drills

Care should be taken not to drill too large a hole at one time. Drilling of

large holes should be done in stages by using small bore drills and gradually

increasing the size as necessary. If this is not done, the drill may bind on

breakthrough, and the torque set up could twist the tool against the user's

wrist.

5.5.4.3 Saws

Hand operated circular saws shall be fitted with spring loaded guards which

allow only the working part of the blade to be exposed. (See Figure 7.)

Portable table saws shall be provided with adjustable guards, anti-kick-back

devices, and push-type start/stop buttons within easy reach of the operator.

(See Figures 8 and 9.) Fixed table saws shall be hard wired to an emergency

electrical disconnect switch that has the capability of locking out in addition

to having start/stop buttons at the operator's location, etc. Portable table

saws must be unplugged for repair, maintenance, or when not in use.

Where a provision is made for a table saw riving knife to be fitted, it shall be

kept clean and properly adjusted to the work at all times. Push sticks must

be provided and used when necessary on all bench saws.

The work area shall be cleaned to prevent excessive build-up of sawdust and

scrap wood.

Operators shall wear eye and hearing protection.

5.5.4.4 Radial Saws (Figure 10)

Radial saws must be provided with:

• An upper hood to enclose the top portion of the blade down to a point

that includes the end of the saw arbor. The sides of the lower, exposed

portion of the blade must be guarded to the full diameter of the blade by

a device that automatically adjusts to the thickness of the stock being

cut.

• Anti-kickback dogs (on both sides of saw) designed to provide adequate

holding power for all thicknesses of ripping stock.

• An adjustable stop limiting the forward travel of the blade beyond the

distance necessary to complete the cut in repetitive operations.

• A saw housing which automatically returns to the starting position.



• A marking on the hood showing the direction of the saw rotation. In

addition, a permanent label must be affixed to the rear of the guard,

reading: "DANGER. DO NOT RIP OR PLOUGH FROM THIS END."

• Start/stop buttons at the operator's position. Additionally, in the case of

fixed saws, each saw must be wired to an emergency electrical

disconnect isolation switch capable of locking out the saw.

5.5.5 precaution requirements

• Personnel who use power tools must be trained and competent in their

use.

• Maintenance of power tools must be systematic. The insulation of

electrical tools and extension leads must be regularly checked by

competent electricians. All results are to be recorded.

• Safety guards and fuses must be kept in position.

• Great care must be taken when operating electrical tools in wet or humid

areas.

5.5.6 Portable Electrical Drills

• Always provide a 'starter' mark for the drill point.

• Always select correct bit for the material being drilled.

• If the bit is long enough to pass through material, protect against damage

and injury on the other side.

• Small pieces of work should be clamped or held down to prevent

spinning by the drill.

• Care must be taken to prevent sleeves and other clothing from being

caught by the drill. It is recommended that sleeves be rolled up above the

elbow.

• Telescopic or similar guarding must be used when operating a bench-

mounted drill.

5.5.7 Portable Grinders

• Grinder operators must wear suitable eye protection ie., goggles or full-

face shields.

• Grinder wheels must be inspected and dressed regularly. Full-face

shields and respiratory protection must be worn when dressing. A

cracked stone may break into pieces and must be discarded.

• Grinding wheels must have the same (or higher) maximum permissible

working speed as the grinder.

• Adjustable shields must be fitted to all grinders. They must not be

removed.

5.5.8 Portable Electric Saws

• Both upper and lower guards must be kept in place.



• Saw blades must be regularly checked and kept in good condition.

• The blades used must be those recommended for the material being cut.

• If a portable saw is adapted for bench top use, it must be securely

clamped with a support designed for this purpose.

• Green or wet materials should be cut slowly and with extra caution.

• Operators exposed to harmful dust, as when cutting concrete, tile, lead or

stone, should wear an approved type of respiratory protection.

• Materials should be checked for nails, hard knots, etc.

5.6 Pneumatic Tools

5.6.1 General

An air compressor shall always be under the supervision of a competent

person. It should always be sited in such a place so as to have adequate

ventilation. Compressors shall not be permitted to operate in confined

spaces without the provision of adequate exhaust ventilation.

All compressed air hoses shall be of the correct size to fit the tool being

used. Any joint in the hoses shall be made with a proper coupler and

secured by safety wire. The hose length shall be kept as short as possible

and placed so as not to be subjected to damage.

Pneumatic tools require clean air to operate efficiently. In every line feeding

a power tool, there shall be an adequate filter and lubricator.

During operation all air tools should be held firmly to prevent them spinning

and jumping. This pressure should be maintained during the stopping

process to prevent injury to the operator's feet and hands.

5.6 .2 Individual Tools, Precautions

5.6.2.1 Jack Hammer and Concrete Breakers

The tool bit retaining spring shall always be securely in position to prevent

the bit from dropping out. The bit must be kept sharp.

Ear, eye and foot protection shall be required when working with this type of

equipment.

5.6 .2.2 Rock Drill

It is extremely important that the operator maintains a firm grip with both

hands and stands in a balanced position. Any other method of using the tool

can cause serious bodily injury.



5.6.2.3 Grinding Machine

This tool is probably the most misused of all the power tools. Care should

always be taken to ensure that the grinding wheel is free from defect before

mounting. Any defect may cause the wheel to disintegrate as it gains

momentum.

Only persons who have been instructed in the proper selection and fitting of

grinding wheels should be allowed to install wheels on tools.

The proper size and type of wheel should be fitted to the tool so that the

maximum permissible running speed of the spindle does not exceed the

maximum periphery speed displayed on the grinding wheel. No grinding

machine shall be used unless the maximum speed is clearly marked on the

case. All wheels shall be fitted with adequate guards in conformance with

ANSI B7-1-1988. (See Figure 1.)

Floor stand and bench mounted abrasive wheels, used for external grinding,

shall be provided with safety guards (protection hoods). The maximum

angular exposure of the grinding wheel periphery and sides shall be not

more than 90o, except that when work requires contact with the wheel

below the horizontal plane of the spindle, the angular exposure shall not

exceed 125o. In either case, the exposure shall begin not more than 65o

above the horizontal plane of the spindle. Safety guards shall be strong

enough to withstand the effect of a bursting wheel. (See Figures 2 and 3.)

Floor and bench-mounted grinders shall be provided with work rests which

are rigidly supported and readily adjustable. Such work rests shall be kept at

a distance not to exceed one-eighth inch from the surface of the wheel. (See

Figure 2.)

Cut type wheels used for external grinding shall be protected by either a

revolving cup guard or a band type guard in accordance with the provisions

of the American National Standards Institute, B7.1-1988 Safety Code for the

Use, Care, and Protection of Abrasive Wheels. All other portable abrasive

wheels used for external grinding, shall be provided with safety guards

(protection hoods) meeting the requirements of this paragraph, except as

follows:

• When the work location makes it possible, a wheel equipped with safety

flanges shall be used.

• When wheels 2 inches or less in diameter which are securely mounted on

the end of a steel mandrel are used.



Portable abrasive wheels used for internal grinding shall be provided with

safety flanges (protection flanges) except as follows:

• If the wheels are entirely within the work being ground while in use.

• When wheels 2 inches or less in diameter which are securely mounted on

the end of a steel mandrel are used.

When safety guards are required, they shall be so mounted as to maintain

proper alignment with the wheel, and the guard and its fastenings shall be of

sufficient strength to retain fragments of the wheel in case of accidental

breakage. The maximum angular exposure of the grinding wheel periphery

and sides shall not exceed 180o.

When safety flanges are required, they shall be used only with wheels

designed to fit the flanges. Only safety flanges of a type and design and

properly assembled so as to ensure that the pieces of the wheel will be

retained in case of accidental breakage, shall be used.

All abrasive wheels shall be closely inspected and ring-tested before

mounting to ensure that they are free from cracks or defects. (See Figure 4.)

Grinding wheels shall fit freely on the spindle and shall not be forced on.

The spindle nut shall be tightened only enough to hold the wheel in place.

(See Figure 5.)

All employees using abrasive wheels shall be protected by eye protection

equipment.

Materials that require grinding shall be placed on the tool rest with moderate

head-on pressure applied. Materials should not be forced or jammed into

the wheel. Grinding the materials on the sides of the wheel is an unsafe

practice which can damage the wheel. A grooved or damaged wheel must

be replaced.

5.6.3 Compressed Air Tools

• The air supply line should be protected from damage by vehicles,

materials, etc.

• Supply hoses, pipes and couplings must be inspected regularly and

damaged items must be promptly replaced or repaired.

• Ear protection may be necessary.

• Compressed air is not to be used for other purposes such as dust

removal, etc. Horseplay involving any use of compressed air equipment

is forbidden.



5.7 Cartridge Operated Tools

5.7.1 General

Cartridge operated tools have a great advantage in that they can be used in

almost any situation without the inconvenience of trailing leads or hoses.

However, it is essential that these tools be operated only by properly trained

personnel who are over 18 years of age. The contractor shall ensure that each

man required to operate such a tool will undergo a thorough training period and

be certified by the tool vendor. Use of cartridge operated tools will be in

accordance with ANSI A10.3-1985 and the manufacturer's specifications and

shall be subject to review and concurrence by the HSE Department.

5.7.2 Storage

Safe and secure storage for cartridges and tools must be provided on the job site.

Storage must be fire proof, dry, must be capable of being locked and should be

sited in a clear, but easily accessible location where constant supervision can be

maintained.

Cartridges and tools must not be stored together. A storage unit providing

positive physical separation of cartridges and tools (i.e., a wall or partition) is

required.

Warning to be posted where cartridges are stored: "DANGER - NO SMOKING

Cartridge Storage".

Ventilation must be provided in the store. Cartons of cartridges must not be

stacked against the wall and ventilation spaces must be left around the cartons.

Only one carton of each strength cartridge shall be open at any one time. All

empty cartons, and intermediate packing, must be removed at once.

Tools must be stored in their carrying cases. No loose cartridges must be in the

carrying cases; all cartridges must be in their color coded boxes.

Only authorized personnel must be allowed access to the store.

5.7.3 Selection and Training of Personnel

No person may operate, clean, maintain, or repair any cartridge tool without

possessing a certificate of competency, issued by an accredited tool vendor or

manufacturer's representative, which identifies the particular model that the

person is qualified to handle.



Personnel for training must be selected with the following points in mind:

1. Must be over 18 years of age.

2. Must be physically fit and have full use of both hands and both eyes.

Should ideally be a tradesman, e.g. plumber, mason, electrician,

joiner/carpenter, etc.

Store men may also need to be trained if they are required to clean and

maintain the tools.

3. Training, both theoretical and practical, must be given by a competent

instructor.

4. The training must follow the manufacturer's instructions as contained in the

handbook of each particular model.

5.7.4 Personal Protective Equipment

Eye Protection shall be worn by the operator and his assistant whenever using

the tools. Goggles must be of a satisfactory standard designed to withstand high

speed impacts and/or, penetrations.

Ear muffs will be available for use at any time and shall be used in confined

spaces.

Safety belts may be required in certain situations where the recoil from the tool

could cause an operator to loose his balance.

5.7.5 Issue and Returns

Supervisor will ensure that a full register of the serial numbers of each tool is

made and kept up to date .A log inventory system of issuing and

returning cartridges and tools against signatures must be initiated and

maintained. See

Figure 12: Cartridge/Tool Issuance Control.

Only personnel in possession of a user certificate will be allowed to withdraw

tools or cartridges from the store.

Only the minimum number of cartridges required for that particular shift's

operation should be issued at any one time.

Cartridges and tools must not be left on the job site at lunch break or at end of

shift but must be returned to the store for safekeeping.

Any loss, either of tools or cartridges, must be reported, at once, to POGC project proponent.



5.7.6 Work Permits

Work Permits will not normally be required for use on job sites.

Where tools will be used in restricted areas (as defined in MA-64-POGC-001

Work Permit Manual), a Hot Work Permit must be obtained before work

commences.

5.7.7 Use

No person may operate, clean, maintain or repair any cartridge tool without

possessing a certificate of competency which identifies the particular model that

person is qualified to handle.

The manufacturer's operating instructions must be followed at all times.

Cartridges are manufactured in different calibers and strengths. There are three

sizes: .25 short, .27 short, and .27 long; and, four strengths, as follows:

POWER LEVEL

NUMBER

COLOR CODE

LETTER CODE

Low 3 Green L Low/Medium 4 Yellow LM Medium/High 5 Red MH

Extra High 6 Purple/Black EX

It is, therefore, imperative that the correct size and strength of cartridge required

for the tool, the fixing, and the material to be fixed onto be properly determined.

A wrongly sized cartridge will cause a stoppage or misfire.

Using a cartridge which is too powerful could cause a ricochet or a spelling or

fracture of the material.



The following General Safety and Operating Rules are common to all types of

tools:

1 As soon as the tool is removed from its carrying case, check to make sure

that a cartridge is NOT LOADED.

2 Inspect the tool before use each day to ensure that it is complete, in good

condition (e.g., clean), and that the safety devices are in proper working

condition.

3 Any tool that is not in proper working order or that develops a defect during

use, shall be immediately withdrawn from service and not used until properly

repaired.

4 Tools shall not be loaded with a cartridge until just prior to the intended

firing time. When loading a tool, point it away from you and anyone else.

Never walk around with a loaded tool; load it where you are working. Never

leave the tool loaded when not in use. Loaded tools shall not be left unattended.

5 Never try to operate the tool without the end of the barrel hard against the

fixing surface.

6 All tools shall be used with the correct shield, guard, or attachment

recommended by the manufacturer.

7 Fasteners shall not be driven into very hard or brittle materials including, but

not limited to, cast iron, glazed tile, surface hardened steel, glass blocks, hollow

tile, terra cotta, marble, granite, slate, etc.

8 Driving into soft or easily penetrable materials shall be avoided unless

materials are backed by another material that will prevent the pin from passing

completely through and creating a flying missile hazard on the other side.

Careful inspection of all materials should be made before deciding on the use of

a cartridge tool.

9 No pins shall be driven into a spelled area caused by an unsatisfactory shot,

or into any existing hole in the material. Care should be taken to ensure that the

new fixing is at least two inches away from any previous hole, and a similar

distance from any welded joint.

10 Pins must not be fired into corner bricks, mortar joints, and must be at least

four (4) inches (100 mm) away from the edge of concrete or brick work and

one-half inch (12 mm) from the edge of steel.

11 Ensure that the correct strength cartridge is used for the pin, fixing and

material involved. For the first, or test firing use the weakest cartridge. Too



strong a cartridge may result in over penetration, or the fastener may rebound or

ricochet.

12 The tool must be held at right angles to the job when firing.

13 In the event of a misfire, the tool should be re-triggered without moving the

tool from the work face. If the shot again fails, then the tool must be held firmly

in the firing position for at least 30 seconds to allow for a possible "Hang Fire"

in the

cartridge. The removal of the misfired cartridge must be as per the

manufacturer's instructions. Do not use nails, knives, etc., to pry the cartridge

loose.

14 Recoil from firing can throw an operator off balance, especially when

working from ladders or scaffolds. Care must be taken to ensure that the

operator has a secure and safe work area. Safety belts should be used if

necessary.

15 Do not leave cartridges loose on the job site or in the carrying case or carry

them in your pockets. Cartridges are of the 'Rim Fire' type and could explode

accidentally if in receipt of a knock from a pin, fixing, or even a bunch of keys.

16 Before returning the tool to the stores, ensure that it is clean and complete

and that all cartridges are in their correct color coded box.

5.7.8 Maintenance and Repair

Before any repair/maintenance work is carried out, check to make sure that the

tool is NOT LOADED with a cartridge.

No person may operate, clean, maintain or repair any cartridge tool without

possessing a certificate of competency which identifies the particular model that

the person is qualified to handle.

Tools must be dismantled, as far as the manufacturer's instructions indicate, at

least once every week and checked for defects and excessive wear before being

cleaned and oiled. If any defect is found, the tool must be made serviceable

before being issued for use.



Only manufacturer's authorized spare parts are to be used for

repair/replacement.

NO CARTRIDGES must be allowed in the repair/maintenance area. Test firing

of repaired tools must be done in a safe location away from work and store or

office areas.

Cartridge powered tools are extensively used for many types of fixing

operations and, when used in the correct manner, will save time. The

manufacturers’ instructions must be strictly adhered to, particularly with regard

to Procedures for loading, fixing and dismantling. The tools must only be used

by personnel trained in their use, and who have been issued with a Certificate of

Competence, or similar, for each tool they are qualified to use.

The safety precautions to be observed for handling and care of cartridge tools

are:

• The operator must be trained in the use of cartridge tools.

• Tools must not be used on materials where the hardness of the material

is greater than of the fastener.

• Cartridge tools must not be used in the vicinity of other personnel due to

the risk of injury caused by ricochets.

• Tools must never be used without a suitable guard or shield.

• Goggles or full-face shields must be worn by operators.

• The cartridges used must be kept in proper containers.

• A loaded cartridge tool must never be left unattended.

• The cartridge tool must be unloaded before carrying out any adjustment

to the safety guards, muzzle or barrel.

• Cartridge tools must not be used in any area where flammable gases,

vapors or explosive dust are present.

CAUTION : IF THE TOOL DOES NOT FIRE ON OPERATION OF THE

FIRING MECHANISM, THE TOOL MUST REMAIN PRESSED AGAINST

THE FIXING SURFACE FOR 15 TO 20 SECONDS TO ALLOW FOR A

POSSIBLE TIME LAG IN CARTRIDGE FIRING. THE MAKER'S

INSTRUCTIONS FOR DEALING WITH MISFIRES MUST BE STRICTLY

ADHERED TO.
