Power tools often require extension cords on construction sites, but these cords are susceptible to damage. Many injuries occur due to problems with electrical outlets, power cords, and extension cords. To prevent injuries, workers should inspect cords daily for damage, protect them from damage, avoid staples and nails, use ground fault circuit interrupters, only use cords temporarily and store them after use, never use damaged cords, ensure cords are rated properly, and keep cords out of high traffic areas.

1. HSE ALERT # POWER CORDS
Power tools are widely used on construction sites.Flexible extension
cords are often necessaryto provide electricity to the tool. Due to the
very reasons they are used, necessaryto provide electricity to the tool.
Due to the very reasons they are used, they are more susceptible to
damage than fixed wiring. Approximately many of these injuries are
related to problems with electrical outlets, power cords and extension
cords.
Safe Work Practices and Tips:
 Inspect all extension cords daily for damage and missing grounding prongs.
 Protect extension cords from damage.
 Never use a metal outlet box as an extension cord.
 Never use Romex or non-metallic cable as extension cords.
 Avoid using staples and nails to hold extension cords in place.
 Use a Ground Fault Circuit Interrupter (GFCI) to protect against any electrical
fault.
 Extension cords should only be used on a temporary basis, unplug and
safely store them after every use.
 Never use a cord that feels hot or is damaged in any way. Touching just one
exposed strand can cause an electric shock or burn.
 Make sure extension cords are properly rated for their intended use and
meet or exceed the power needs of the appliance or tool being used.
 If an extension cord is needed for a longer period of time, temporary power
taps can be used when insufficient electrical receptacles are available.
 Ensure that all extension cords are certified by a nationally recognized
testing laboratory such as UL, CSA, or ETL.
 Keep extension cords out of high traffic areas like doorways or walkways
where they pose a tripping hazard.
 Never run extension cords through walls or ceilings. This may cause the cord
to overheat, creating a serious fire hazard.
