Electrical Installations – Safety & Execution

fire extinguisher safety

For temporary and/or permanent electrical equipment used on the job site:

Lock out/tag out procedures must be followed:

  • If systems need to be energized for work, only properly trained, licensed and qualified persons may work on these systems and only with proper controls in place.
  • Qualified persons must don the appropriate Personal Protective Equipment (PPE) as specified in the specific procedure for that equipment.
  • Extension cords are not to be used in lieu of permanent wiring. Extension cords used with portable electrical tools and appliances shall be of three-wire types.
  • Grounds are never to be removed from equipment or extension cords.

Tool and equipment condition:

  • All wiring and electrical equipment, tools and machinery shall be in excellent repair and part of a sound Preventive Maintenance Program with frequent inspections and full documentation.

Temporary lights:

  • Temporary lights and lighting where exposed to breakage, shall be equipped with guards to prevent accidental contact with the bulb.
  • Temporary lights shall not be suspended by their electric cords unless cords and lights are designed for this means of suspension.
  • Splices are not permitted.

Electrical lines, extension cords, and cables:

  • Do not to lay them on floors or in walkways, etc.
  • Secure and place in doorways and work areas so they won’t be damaged.
  • Do not use flexible cords as a substitute for fixed wiring, run flexible cords through walls, ceilings, floors, doorways, windows, attach to building surfaces, or conceal behind building walls, ceilings, or floors.

Panel boards, access, and ground fault systems:

  • These must have dead fronts on them at all times, except when being serviced.
  • All electrical equipment should have at least a three foot clearance in front of the equipment.
  • The area needs to be controlled for unauthorized access.
  • A “ground fault system” is used to prevent shock hazards. This may include the use of “ground fault circuit interrupters” (GFCIs) or an “assured equipment grounding program”.
