Electrical Emergency Procedures



The DC supplies at each workbench can be turned off by the switch on the lab bench power panel.

The AC outlets on the bench are not switched, and can only be turned off from the circuit breaker panel. The main breaker in the breaker panel turns off the power to the entire lab.

 

When dealing with any electrical hazard, any possible contact with metal objects must be avoided. Never touch any metal near the site of an electrical hazard involving smoke, fire or sparks.

In the instructions below, an action can be performed safely if it can be done without coming into contact with fire, sparks, or any metal near the site of the hazard.

  1. Smoke or Fire
    1. If you smell or observe smoke or fire from a circuit, turn off power to the circuit if you can do so safely.

    2. If you smell or observe smoke or fire from a piece of equipment, turn off power to the equipment if you can do so safely.

    3. If turning off power cannot be performed safely, pull the plug if you can do so safely.

    4. If neither turning off power or pulling the plug can be done safely, turn off power to the whole room using the emergency main breaker.

  2. Sparks
    1. If you observe sparks from a circuit, turn off power to the circuit if you can do so safely.

    2. If you observe sparks from a piece of equipment, pull the plug if you can do so safely.

    3. If neither turning off power or pulling the plug can be done safely, turn off power to the whole room using the emergency main breaker.

  3. Electrocution
    1. If you observe someone apparently being electrocuted, turn off power to the whole room using the emergency main breaker. Do not attempt to touch a person or any equipment nearby if you suspect electrocution.
