  1. Electrical Safety For Office, Facility, and Laboratory Employees Tulane University October 2006 Tulane University - Office of Environmental Health & Safety (OEHS)

  2. Objectives • To identify proper use of electrical extension cords, multiple outlet strips, and portable electric heaters. • To identify safe electrical practices. • To review Electrical Safety for Facilities Services Tulane University - Office of Environmental Health & Safety (OEHS)

  3. Electrical Extension Cords • Grounded, heavy gauge extension cords are OK for temporaryuse with portable equipment, e.g., maintenance power tools, audio-visual equipment, housekeeping appliances. • The use of extension cords in lieu of permanent wiring is a fire code violation. Tulane University - Office of Environmental Health & Safety (OEHS)

  4. Multiple Outlet Strips • Multiple outlet strips with circuit breaker or fuse and power cord no > 6 ft. may be used for computer work stations only. • Use of linked cord-sets as shown in photo is prohibited. Tulane University - Office of Environmental Health & Safety (OEHS)

  5. Electrical Safety • Contact Facilities Services if additional electrical outlets are needed OR if you see an obvious electrical hazard like this → Tulane University - Office of Environmental Health & Safety (OEHS)

  6. Portable Electric Heaters • Prohibited except if provided by Facilities Services/Plant Operations when heating issues cannot be resolved. • Contact Facilities Services/Plant Operations regarding heating issues. Tulane University - Office of Environmental Health & Safety (OEHS)

  7. Electrical Panels • Keep panels unobstructed with 36 inches clearance. • Keep panels free of combustibles & flammables storage. (The gray rectangles in the photo are electrical panels which are improperly blocked by storage of combustible materials.) Tulane University - Office of Environmental Health & Safety (OEHS)

  8. Safety Practices • Purchase & use equipment with grounded (3-prong) power cords or double-insulated appliances. • Improper use of adapters or “cheaters” on grounded plugs is a fire code violation. • Contact OEHS or Facilities Services for more information. Tulane University - Office of Environmental Health & Safety (OEHS)

  9. Safety Practices • Ground Fault Circuit Interrupters (GFCIs) monitor current going in and out of an electrical device. If an imbalance is sensed, the GFCI shuts off the power instantly to prevent injury. • GFCIs are installed in electrical outlets where there is a greater risk of electric shock – e.g., wet areas (near sinks/faucets). Tulane University - Office of Environmental Health & Safety (OEHS)

  10. Safety Practices • Keep combustible materials/flammable liquids away from electrical appliances & sources of heat: • Bacti-cinerators, Bunsen burners, hot plates • Coffee pots, ovens • Heat guns, light bulbs, etc. • Do not overload outlets Tulane University - Office of Environmental Health & Safety (OEHS)

  11. Safety Practices • Do not run power cords under carpeting, across walkways, or through doorways and walls→ • Do not use metal ladders near energized electrical equipment. Tulane University - Office of Environmental Health & Safety (OEHS)

  12. Defective Equipment • Examples of defective equipment: • Missing ground prong • Spliced/taped/broken power cord • Frayed or exposed wire • Sparks, smoke, or shock when energized. • Take equipment out of service and tag it to warn others. • Report hazard for repair by trained/qualified personnel or discard equipment. Tulane University - Office of Environmental Health & Safety (OEHS)

  13. Electrical Safety for Facilities Services • Lock and tag electrical switches when doing repair work. • See Equipment Lockout/Tagout in “Facilities,” (Section 24 of Environmental Health and Safety Policies & Procedures Manual.) Tulane University - Office of Environmental Health & Safety (OEHS)

  14. Electrical Safety for Facilities Services • When working on electrical distribution panels, sub-panels, motor controls, or fixed equipment, ensure power sources are disconnected and tagged out of service, then test to ensure power is off before beginning work. • Wear proper Personal Protective Equipment & use proper safety equipment. Tulane University - Office of Environmental Health & Safety (OEHS)

  15. Electrical Safety for Facilities Services • Upon completion, test the system before putting it in service, restore controls to normal operations, remove tags, and replace panel covers. Tulane University - Office of Environmental Health & Safety (OEHS)

  16. Review • Extension cords are only a temporary source of power. • Multiple outlet strips may only be used with computer configurations. • Keep electrical panels unobstructed and free of nearby combustible materials. • GFCIs should be installed on electrical outlets near wet areas. Tulane University - Office of Environmental Health & Safety (OEHS)

  17. Review • Separate combustibles/flammables from heat sources. • Inspect electrical equipment. Remove defective equipment from service and tag. • Facilities Services is to use Lockout/Tagout when conducting repair work on energized equipment.
