I. definition
Indirect Action Tool – A powder actuated tool that uses the expanding gases from the explosion of the ammunition to drive a piston that drives the fastener into the material. The fastener is driven by the inertia of the piston. The fastener itself does not have enough inertia to create free flight once away from the piston.
Fresh Rock – Rock or stone in its natural state, unprocessed and unaltered.
Low speed tool a powder actuated tool in which the speed of the fastener at 6.5 feet (2 meters) from the nozzle is less than 328 feet (100 meters) per second.
Powder Actuated Tool – A tool that uses an explosive fastener nail gun cartridge to drive fasteners into various materials; also known as a nail gun.
2. General Provisions
Only use indirect-acting, low-speed tools. Use of powder actuated fastening tools must comply with state and local government requirements and ANSI 10.3-1985, or meet local code requirements.
operations
2.1 Training Standards – Operators must receive comprehensive training in the operation, maintenance and fastener selection of powder actuated tools. Manufacturer’s representatives can provide training and licenses to tool operators upon request.
When operating this tool, the operator must carry a card or license indicating successful completion of a training course. The card or license must indicate the model of tool it is qualified to operate.
2.2 Protective Equipment – Fasteners and sockets may only be used with powder-actuated fastening tools for which they are specifically designed. All such tools must be used with appropriate protective screens, guards, or accessories recommended by the manufacturer. Operators and nearby workers must wear safety glasses with side shields, full face shields, and, depending on their location, hearing protection. Operators must also wear foot protection if driven fasteners could shatter material and fall onto the operator’s feet. For more information on foot protection, see Engineering Standard S8G.
2.3 Restrictions – Powder actuated fastening tools may not be used to drive fasteners into surfaces made of hardened steel, cast iron, glazed tile, hollow brick, cinder block, marble, granite, fresh rock, or similar ultra-hard materials, Brittle or breakable materials. Powder-actuated fastening tools must not be used near explosive or flammable materials or in hazardous electrical areas (Class I, II, or III) without an applicable hot work permit. For more information on work permits, see CSM B-12.1.
The cartridge of a powder-actuated fastening tool may only be loaded prior to the scheduled firing time. Loaded tools and cartridges must not be left unattended. Never point the powder fastening tool at anyone.
Powder actuated fastening tools should not be used on easily penetrated materials unless such material is backed by something on the back that will prevent the pin or fastener from fully penetrating and creating a projectile hazard on the other side.
When fastening other materials (for example, 2×4-inch lumber) to a concrete surface, fasteners with rod diameters not exceeding 7/32-inch are permitted to be driven less than 2 inches from the unsupported edge or corner of the work surface.
