Replace open front plugs with dead front plugs. Dead front plugs are sealed and present less danger of shock or short circuit. Do not use light duty power cords. Do not carry electrical tools by the power cord. Do not tie power cords in tight knots.
Knots can cause short circuits and shocks.
Loop the cords or use a twist lock plug. When a loss is detected, the GFCI turns the electricity off before severe injuries or electrocution can occur. A painful shock may occur during the time that it takes for the GFCI to cut off the electricity so it is important to use the GFCI as an extra protective measure rather than a replacement for safe work practices. GFCI wall outlets can be installed in place of standard outlets to protect against electrocution for just that outlet, or a series of outlets in the same branch. A GFCI Circuit Breaker can be installed on some circuit breaker electrical panels to protect an entire branch circuit.
