Where power tools, lamps or other electrical equipment are subject to hard usage, the cords shall be coated or provided with heavy-duty insulating material.
Portable electrical equipment, including temporary lighting, used outdoors or in wet or damp locations, shall be protected by an approved ground fault circuit interrupter of a Class A type installed at the receptacle or the circuit panel.
A ground fault circuit interrupter shall not be used in place of grounding except as permitted by the Canadian Electrical Code.
Repairs or adjustment
Before removing or changing any attachment or adjusting or repairing a power tool, the worker shall disconnect the tool from its power source in a manner that ensures it cannot be reconnected inadvertently.
Air supply lines
Before disconnecting the air supply from a portable power driven tool, a worker shall shut off the air supply and bleed the air line, unless the air line has a quick disconnect coupling that makes such precautions unnecessary.
Air tool supply lines
A worker shall not use a pneumatic portable tool or air hose so as to direct the air stream against any person.
A worker shall not use hydraulic, pneumatic, chemical or electrical lines or hoses in a manner that creates a safety hazard to workers.
General requirements for chain saws
