Powder-Actuated Tools

Powder-actuated tools use a gunpowder charge to drive fasteners into concrete and steel. They work like a firearm, and must be treated like one.

• Construction

Training is required

Only workers trained in the operation of the specific tool may use it. Manufacturers issue an operator card after training. Carry it.

Before use

• Test the tool each day before loading, per the manufacturer, to make sure safety devices work
• Choose the right load strength. Start with the weakest load and work up. Loads are color-coded by power level.
• Check the base material: right thickness, not too hard, brittle or soft
• Post signs warning others when tools are in use

Rules

• Load the tool only just before firing.
• Hold the tool perpendicular to the work surface.
• Wear safety glasses, a face shield and hearing protection.
• If the tool misfires, hold it in position for at least 30 seconds, try again, then follow the manufacturer’s misfire procedure.

• Never point the tool at anyone, loaded or not.
• Don’t fire into easily penetrated materials (where the fastener can pass through), very hard or brittle materials (cast iron, glazed tile, hardened steel, some rock), or near edges and spalled areas.
• Don’t use in explosive or flammable atmospheres.
• Don’t leave a loaded tool unattended.
