4.14 Hand, Power, Pneumatic, and Powder-Actuated Tools

These guidelines establish general requirements for operating hand and power tools safely. They provide best practice guidelines. Employees should be trained in the proper use of all tools. Workers should be able to recognize the hazards associated with the different types of tools and the safety precautions necessary.

4.14.1 General Rules

  • Properly maintain all tools.

  • Before using the tools, inspect them for damage and ensure they will operate safely.

  • Dispose of tools that are in poor condition and considered unsafe. Replace wooden handles that are loose, cracked, or splintered. Do not tape or lash handles with wire to temporarily repair an unsafe condition.

  • Use tools only for what they were designed to do. Operate tools in accordance with the manufacturer’s instructions.

  • Use the proper tool for the job to be performed. Do not use makeshift or substitute tools not designed for the job.

  • Do not throw tools from place to place or from person to person.

4.14.2 Hand Tools

  • Repair or replace impact tools, such as chisels or punches, that become mushroomed or cracked.

  • Keep screwdrivers sharp and even. Do not use a screwdriver with a broken or rounded point. Do not use a screwdriver as a pry bar or chisel.

  • Store sharp-edged tools in a safe manner. Do not carry sharp-edged tools in clothing pockets.

  • Do not use a pipe (cheater bar) to extend a wrench handle unless the wrench was designed for such use. Do not use shims to make a wrench fit.

4.14.3 Power Tools

  • Ground non-current-carrying metal parts of portable electric tools when connected to a power source unless the tool is an approved double-insulated type.

  • Never use a tool with a broken or frayed electrical cord or with the grounding prong removed.

  • Inspect all power tools for general serviceability and the presence of all applicable safety devices.

4.14.4 Pneumatic Tools

  • Tether pneumatic tools to the air hose and attach hose sections to each other and the compressed air source unless all these parts have a secure, quick disconnect coupling.

4.14.5 Powder-Actuated Tools

  • Allow only employees who have been trained to operate the particular tool in use to operate a powder-actuated tool.

  • Using the manufacturer’s recommended method of testing, test the tool each day before loading to see that the safety devices are in proper working condition.

  • Do not load tools until just prior to the intended firing time. Neither loaded nor empty tools are to be pointed at any person.

  • Keep hands clear of the open barrel end of the tool.

  • Do not leave loaded tools unattended.

  • Do not use powder-actuated tools in an explosive or flammable atmosphere.
