Pneumatic Tool Safety
- All hoses exceeding 1/2-in (1.3 cm) inside diameter must have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.
- Compressed air pressure and volume must be regulated according to manufacturer's rating for the tool.
13.D.02 Pressure must be shut off and exhausted from the line before disconnecting the line from any tool or connection.
13.D.03 A safety lashing must be provided at connections between tool and hose and at all quick makeup type connections.
13.D.04 Hoses must not be used for hoisting or lowering tools.
13.D.05 Airless spray guns of the type which atomize paints and fluids at high pressures [1,000 lb (453.5 kg) or more, per square inch] must be equipped with automatic or visible manual safety devices which will prevent pulling of the trigger to prevent release of the paint or fluid until the safety device is manually released. In lieu of the above, a diffuser nut that will prevent high-pressure velocity release while the nozzle tip is removed plus a nozzle tip guard that will prevent the tip from coming into contact with the operator, or other equivalent protection may be provided.
13.D.06 Impact wrenches must be provided with a locking device for retaining the socket.
