A Nail Gun Can Fire Before You Expect It

Controls to confirm

• Select and check the safer trigger: use a full sequential trigger nailer, as OSHA and NIOSH recommend, and train the operator on the actual model. Confirm the trigger type from its label and manual. Check the trigger and contact safety tip under the manufacturer's procedure; never bypass either. Remove a damaged or malfunctioning nailer from service.
• Control the firing path: clamp timber where practicable rather than holding it close to the nose. For placement work, keep hands at least 12 inches (about 30 centimetres) from the nailing point, following OSHA/NIOSH guidance. Check for knots and metal fittings, and keep people clear of the far side and possible deflection path. Wear suitable impact-rated eye protection and hearing protection.
• Make pauses and handovers safe: keep your finger off the trigger when not nailing, and never point the tool towards yourself or anyone else. Disconnect the compressed-air supply before clearing a jam, maintenance, passing the nailer to another person, climbing stairs or ladders, or leaving it unattended. Report every injury and seek immediate medical attention, including for a small-looking hand puncture.

Today’s action

Before the next fastening task, have the operator and supervisor check the manual, trigger system, clamping arrangement and clear firing path together. Demonstrate the approved air-disconnection procedure before work starts.
