Objective of Tools Maintenance
Objective of Tools Maintenance is to ensure that tools are in good condition and safe to use.
Tools Maintenance Requirement
- Each Construction Division using or intending to use an explosive powered tool must appoint a competent person in writing who has received appropriate training to be responsible for the correct storage and maintenance of all explosive powered tools used by the Construction Divisions.
- Each explosive powered tool must be numbered and a logbook for each tool must be maintained.
- A competent person must check each explosive powered tool before use.
- Each explosive powered tool must be cleaned and examined at least once every week and the findings of the examination entered into the appropriate logbook.
Storage of Tools
- When not in use the explosive powered tools and cartridges must be stored in place inaccessible to unauthorized persons.
- The operators of explosive powered tools are to ensure that the tools are not stored while loaded.
- Only cartridges suited to the specific tool and the work to be performed are to be used.
- The operator must use a face shield when using an explosive powered tool to protect the face and eyes from flying fragments or particles.
- No loaded explosive powered tool must be left lying around while not in use, but must be placed in its container after first being unloaded.
- No cartridge must be inserted until after the nail or stud is loaded and no tool must be operated unless it is at right angles to the fixing surface.
- Fixing with an explosive powered tool must not be done less than 100 mm from the edge of concrete or brick and not less than 12 mm from the edge of steel.
- All operators must be conversant with the misfire procedure.
- If the tool should misfire then it must be held against the work surface for 30 seconds and the trigger pulled again while the tool is still against the work surface.
- Should the tool misfire again a further 30 seconds must be waited before the cartridge is ejected and disposed of.
Pneumatic Power Tool
- The Pneumatic Power Tool must be secured to the hose by some positive means to prevent the tool from becoming accidentally disconnected.
- Safety clips must be securely installed and maintained on pneumatic impact (percussion) tools to prevent attachments from being accidentally expelled.
- Safety clips must be securely attached at all couplings on the hose to prevent couplings from flying about should they become dislodged from the hose or if the coupling comes adrift.
- All pneumatically driven nailers, staplers, and other similar equipment provided with automatic fastener feed, which operate at 6 bar (600kpa) pressure at the tool must have a safety device on the muzzle to prevent the tool from ejecting fasteners, unless the muzzle is in contact with the work surface.
- Compressed air shall not be used for cleaning purposed except where reduced to 2 bar (200kpa) and then only with approved eye and face protection and only if no danger is posed to any other person. At no time must compress air be used to clean down an employee’s person.
- The manufacturers safe operating pressure for hosed, pipes, valves, filters, couplings and other fittings must never be exceeded and must be clearly indicated at the outlet connection of the compressor and at other strategic places on the hose or pipe.
- The use of hoses for hoisting or lowering tools or material is prohibited.
- All hoses exceeding 15 mm inside diameter must have a safety device at the source of supply or branch line to reduce pressure in the case of hose failure.
- Airless spray guns of the type which atomise paints and fluids at high pressure (70bar/7000kpa) must be equipped with automatic or visual manual safety devices which will prevent release of the paint or fluid until the safety device is manually released.
- All pneumatic angle grinders are required to have the spindle speed tested before being used for the first time on a Project and thereafter at least once every three months. The results of the Tachometer Test may be done during the quarterly examination and must be entered in the appropriate register. The maximum revolutions per minute must be displayed on the body of the grinder.
- A competent person must examine all pneumatic powered tools at least once every three months and the results of the examination entered the appropriate register.
