No. 03 - Safe Use of Hand & Power Tools

General

  • Always use the correct tool for the job - never makeshifts.

  • Do not borrow tools from other trades or other contractors - see your supervisor.

  • Make sure the tool is in good condition.

  • Check wooden handles regularly for splits and cracks, and to ensure that wedges are tight.

  • Keep tools clean and dry, with moving and adjustable parts lightly oiled.

  • Cutting edges must be kept sharp.

  • Worn or damaged tools must not be used - report them to your supervisor.

  • Do not leave tools lying around where persons could fall over them.

  • Do not leave them at heights where they could fall on to persons below.

  • Report any defect in any tool or any system of work without delay.​​​​​​​

Further detailed guidance is below for each individual tool, use the sections you require.

Picks, Shovels and spades

  • Picks and shovels must be kept clean, and in safe condition with handles free from cracks and splinters.

  • A shovel blade should not be allowed to become blunt, turned, split or jagged - if it does, report it to your supervisor.

  • Pick head points must be sharp.

  • A pick head must be secure on the handle - if it is not, report it.

  • When using a pick, establish a firm footing with legs apart. Strike the blow so that the point of contact is within easy reach, but not too close to the feet.

  • Safety boots with steel toe caps are essential.

  • Check that the surrounding area, including overhead, is clear of obstructions and people.

  • Once damaged, picks and shovels must not be used

Hammers​​​​​​​

  • Heads must be firmly and accurately set, secured by proper wedges.

  • Heads showing any signs of cracking or damage must be replaced at once.

  • Shafts must be in good condition.

  • Always use the correct hammer for the job, e.g. cross pein or claw hammer for carpentry work; ball pein for engineering work; and club hammer for heavy work.

  • A ball pein hammer must not be used to drive nails.

  • Cartridge tool pins must not be driven with a hammer.

  • Let the hammer do the work by using one that is large enough - the only energy required is for lifting it and projecting it against the object.

Screwdrivers

  • Not to be used as chisels, drifts or wedges.

  • To be of the correct size - it must be capable of driving the screw with little effort.

  • To be properly ground to fit the slot in the screw.

  • Pliers or grips must not be used to obtain additional leverage.

  • Do not hammer the handle.

  • Do not use with a damaged handle - hand injuries could result.

  • Do not carry an unprotected screwdriver in your pocket.

Cold Chisels

  • The cutting edge must be kept sharp.

  • When burring develops the shaft must be re-ground.

  • It is important to select the correct size of chisel for the job, and a hammer of the correct weight.

  • Hold between the thumb and forefinger with a loose grip.

  • Keep your eye on the cutting edge and strike firmly.

  • Rubber mushroom shrouds must be in good condition

  • Always wear high impact protective goggles.​​​​​​

Hand Saws

  • The sharper the saw, the safer it will be and the more accurately it will cut.

  • Rip saws are for cutting with the grain; cross-cut saws are for cutting across the grain.

  • Timber being cut must be firmly secured or supported.

  • Before making a cut look out for knots and nails.

  • A cut should be started by drawing the saw upwards until it bites the wood, using the thumb of the disengaged hand as a guide at the side of the blade.

  • Use long strokes and do not exert too much pressure.

Files and Rasps

  • To be equipped with sound, tightly fitted handles.

  • Keep teeth clean by the use of a wire brush.

  • Protect the teeth when not in use - do not leave lying about.

  • Use only sufficient pressure on the file to keep it cutting.

  • A file must not be used as a chisel or pinch-bar - the tang end is soft and will bend easily, the body is brittle and will break easily.

  • It is particularly dangerous to hammer a file as it will shatter and pieces may fly.

Spanners and Wrenches

  • Misuse and carelessness can cause injuries to the hands.

  • Spanner lengths are graded to provide sufficient leverage on the nut for which they are intended.

  • Use only the right size spanner - checking first to ensure that the jaws are in good condition.

  • Attempts to increase the leverage can strip the thread of a nut or snap the bolt off and possibly increase the risk of the user falling.

  • Adjustable spanners must have square and undamaged jaws. They are liable to snap if struck with a hammer.

  • Pipe wrenches must be large enough for the job, with the jaw teeth clean and sharp, with the knurl, pin and spring undamaged.

  • Pipe wrenches, like adjustable spanners will not withstand hammer blows.

  • Care must be taken to ensure that the grip on a wrench will not endanger you should the tool slip - especially important when working overhead.

  • Work at heights with pipe wrenches should be undertaken, not from stepladders or trestles, but from properly constructed scaffolds.

  • Do not leave in elevated locations from which they could fall.

Pliers

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

  • Slip-joint pliers are for gripping round objects only.

  • Pliers misused as spanners will damage nuts.

  • They are not designed for pulling nails - pincers or a claw hammer should be used.

  • When cutting wire under tension, high impact safety goggles must be worn.

  • Must be kept lightly lubricated.

Knives

  • Knives must be kept sharp - the excessive pressure required to use a blunt knife is likely to result in an injury when the knife slips.

  • Many knives have a specific function and special training may be required - if in doubt, ask.

  • When not in use, knives must be sheathed or have the blades retracted.​​​​​​​​​​​​​​

Safe use of Power Tools

Abrasive wheels

  • Do not mount or use an abrasive wheel or cutting disc unless you have been trained and authorised to do so.
  • Always wear Grade 1 impact resistant eye protection BS EN166B.
  • Adjust the guard so as to expose the minimum wheel surface necessary.
  • The speed of the machine must not exceed the maximum permissible speed of the wheel or disc.
  • Adjust the tool rest or guard to the minimum practicable distance between the wheel, and the tool or cutting surface.
  • Keep your fingers away from the cutting edge of the wheel or disc.
  • Use the correct grade of wheel or disc for the work in hand.
  • Never use the side of the wheel or disc to grind unless it has been designed for this purpose.
  • Do not exert excessive pressure on the wheel or disc.
  • Run a replacement wheel or disc for one minute before using. Ensure that people stand clear.

  • Ensure there is sufficient length of cable.
  • Take up the correct stance - behind and in line with the saw.
  • Ensure the working area is free of obstructions.
  • Report any defect in the equipment or the system of work.

  • Allow at least 76 mm. (3 ins.) from the edge of concrete or brickwork.
  • Hold the tool at right angles to the surface when firing.
  • Wear high impact resistant eye protection.
  • Always wear ear protection.
  • In the event of a misfire, wait one minute before unloading.
  • Never leave the tool loaded when not in use.

  • Do not hold the workpiece by hand, always use a clamp, vice or jig.
  • Do not remove swarf by hand, use a brush or stick.
  • Always use the guard to the chuck and bit.
  • Ensure that you have no loose clothing or long hair which could get caught up by the chuck or bit.
  • Do not wear ill-fitting gloves while operating the drill.
  • If the drill is fitted with a tripping device of the telescopic probe type, make sure it extends as low as possible.
  • Keep cleaning rags away from the revolving bit.
  • Always make sure the chuck key is removed before starting the drill.
  • If the work comes loose, stop the drill and tighten the holder.
  • Concentrate on the operation and do not talk to others while drilling.
  • Avoid drill breakage by easing off the pressure while breaking through.
  • Support thin material.
  • Use only sharp, properly ground drills.
  • Clean up as you go.
