Electrocution Safety


Inspection of extension cords / power tools

All employees should be inspecting their tools on a daily basis before use; any defected tools should be given to your supervisor and taken out of service or repaired.

Extension cords should be of a heavy duty type and should have no damage to the insulation. The ground prong should also be in place before using. Three conductor “flat” cords or two conductor cords shall not be used.

Aluminum ladders

Aluminum ladders are conductors of electricity and their use should be discouraged on a construction project.

GFCI Protection – 100%

GFCI protection is required on all 120 volt 15 and 20 amp circuits which are used for temporary power.

If GFCI’s are not used the contractor can use the assured grounding program

Welding machine receptacles, generators and house power receptacles should also be protected by GFCI’s.

Lockout / Tag-out Programs

Electrical contractors should all have a complete and comprehensive lockout / tagout program. All trades on site should always respect a lockout / tagout; it shall only be removed by the individual that put it in place.

Exposure to energized components

Electrical contractors will be responsible for protecting the other trades from the hazards of electricity.

Panel covers, switch gears, junction boxes, disconnects, etc. should be closed and secured if energized and labeled as such. Energized electrical rooms should have a door in place and be locked to prevent unauthorized entry.

Overhead / underground power hazards

All trades should be aware of the electrical hazards in their work areas. Care should be taken and the minimum clearances should be observed when working around overhead power lines. Underground feeders should be located prior to digging on any project.
