Today, laboratories rely on a vast array of electrically powered equipment. To work safely with this equipment, employees need to understand how electricity works, be aware of common electrical hazards and know how to use electricity safely.

Atlantic Training’s "Electrical Safety in the Laboratory" training video program emphasizes the need for safety when using electricity, and discuss how to reduce the potential for accidents involving electrical shock, fire and explosions. Topics covered in these products include:

Video Transcript

One of the most important electrical safety procedures is the use of grounds and circuit protection devices. The least understood and most violated of all OSHA regulations are the electrical safety requirements for grounding. The most familiar example of grounding is the electric rod which extends to the highest point of a building to attract lightning and carries the electrical charge down a conducting wire to dissipate it safely below the ground. The term grounding refers to both equipment you work with and the electrical system providing the power. If any part of your body touch the enclosure your body provides the shocking path to ground. A correctly installed equipment ground provides a current path that enables protective devices such as circuit breakers and fuses to operate when a fault occurs. The GFCI can be a circuit breaker type, portable type, receptacles or built in to the extension cord. The GFCI is not a circuit breaker, it is a current monitor and reacts faster to prevent electrical shock to you. Unsafe electrical extension cords are the most common causes of electrical shock.
