Nail guns and cartridge-actuated fixing tools fire fasteners at high velocity into timber, concrete, and steel. They can penetrate the human body with lethal force. Accidental discharge, ricochet, and blow-through are the most common causes of nail gun injuries on UK sites. This talk covers the safe use of these tools and the controls that prevent serious injury.
Key Hazards
Penetrating injuries from accidental discharge of nails into the body
Ricochet injuries from nails deflecting off hard surfaces or reinforcement
Blow-through penetration where fixings pass completely through thin materials
Hearing damage from repeated high-impulse noise during sustained fixing work
Control Measures
Ensure only trained and competent operatives use nail guns and cartridge fixing tools on site.
Check the tool before each use for damage, correct operation of the safety nose contact, and trigger lock.
Never point a nail gun at any person, even when you believe it is unloaded or disconnected.
Keep your free hand well clear of the line of fire and fixing point during every shot.
Check behind the material being fixed to confirm no one is on the other side before firing.
Use the correct fastener type and cartridge strength for the material and thickness being fixed into.
Wear safety glasses and hearing protection during all nail gun and cartridge tool operations.
Disconnect the air supply or remove the cartridge strip before clearing jams or carrying the tool.
Store nail guns and cartridge strips securely when not in use to prevent unauthorised access.
Remember
