  1. ELECTRICAL SAFETY TOOL BOX SESSION Georgia Tech Safety and Health Consultation Program

  2. INSPECTION, INSTALLATION AND USE OF ELECTRICAL EQUIPMENT • The following must be inspected before each use: • Electrical extension cords or temporary wiring, • any equipment connected by cord and plug, and • any portable electric hand tool.

  3. COVERS OR ENCLOSURES • All energized parts of electrical equipment or connections must be guarded to prevent accidental contact by a worker

  4. EXTENSIONS CORDS USED AS TEMPORARY WIRING • Extension cords used must be designed for the intended application • Plugs and the covering or electrical insulation material of the cord must be in good condition (no evidence of damage) • Extension cord plugs must always have a ground pin

  5. Ground Pin

  6. PROTECTION OF EXTENSION CORDS(TEMPORARY WIRING) • When run through holes, cords shall be protected from sharp edges • Never submerge extension cords in water • Do not expose cords to excessive heat, unless the cord has been designed for high temperature applications

  7. Ga Tech Safety and Health Consultation Program

  8. PLANNING THE WORK • Plan ahead to control any potential electrical hazard • The minimum working distance from overhead power lines is 10 feet • If you have to work at less than 10 feet from an overhead power line, then the electrical current must be disconnected

  9. ACCESS • Electrical extension cords used in the working area and in passage ways to the work area shall be installed so that: • they do not become a potential hazard for workers (tripping) • they are not physically damaged by traffic

  10. Ga Tech Safety and Health Consultation Program

  11. TEMPORARY ELECTRICAL RECEPTACLES • Shall be protected with approved covers • If metal covers are used, they shall be grounded

  12. WHAT IS A GFCI? • GFCI is a device that senses small imbalances in an electrical circuit caused by the electrical current leaking to ground. • If this imbalance occurs, the GFCI shuts off the electricity within a fraction of a second

  13. ASSURED EQUIPMENT GROUNDING PROGRAM • An assured equipment grounding program is allowed by OSHA but rarely put into practice due to: • The time required for an adequate implementation and follow up • The program may provide a false sense of safety
