Electrical Hazards

Electrical hazards exist in every laboratory. It is important that all work is conducted with electrical safety in mind, and that equipment adheres to electrical codes.

  1. Regularly inspect tools, equipment, extension cords and plugs for worn spots and exposed wires. Do not use damaged tools or equipment - report them to your supervisor.
  2. Keep switch boxes clean and closed.
  3. Repairs on broken power tools or modifications to equipment may only be performed by competent personnel.
  4. Use only CSA/UL approved equipment.
  5. Electrical outlets must have a grounding connection and plugs must be three-pronged. Ensure that electrical equipment has been properly grounded.
  6. Install ground-fault interrupters (GFIs) in areas within 6 ft of a water source (e.g. sinks).
  7. Do not use extension cords as permanent wiring.
  8. Circuit breaker panels must be easily accessible and clearly marked.

All equipment in the lab, from technical apparatus to general use items, must be approved. The Electrical Safety Certification page outlines the criteria for approval and procedures for purchasing or obtaining approval for electrical devices.
