While performing your facility inspection keep an eye out for electrical hazards. Frequently found problems include improper use of extension cords or cords with cut, torn or frayed insulation, exposed wiring, missing grounding plugs, open electrical panels, and over-loaded circuits. Less obvious hazards are present on cage changing tables, biosafety cabinets, and wet vacuum systems. Pay very close attention to wet areas. First, equip all electrical power outlets in wet locations with ground fault circuit interrupters, or GFCI, to prevent accidental electrocutions. GFCIs are designed to "trip" and break the circuit when a small amount of current begins flowing to ground. Wet locations include outlets within six feet of a sink, faucet, or other water source, and outlets located outdoors or in areas that get washed down routinely. Specific GFCI outlets can be used individually or install GFCI in the electrical panel to protect entire circuits.

 

Improper use of flexible extension cords is one of the most common electrical hazards. Extension cords should never substitute for permanent wiring. Check the insulation and make sure it is in good condition and continues into the plug ends. Never repair cracks, breaks, cuts, or tears with tape. Either discard the extension cord or shorten by installing a new plug end. Take care not to run extension cords through doors or windows where they can become pinched or cut. Use only grounded equipment and tools and never remove the grounding pin from the plug ends. Do not hook multiple extension cords together to reach your work, just get the right length cord for the job.

 

Another thing to check is the electrical panel. Ensure a three-foot clear space is kept in front of these at all times. Also, clearly label each circuit breaker. Finally, use of hanging pendants or electrical outlets are widespread in animal care facilities to help keep cords off floors and out of the way. Check electrical pendants for proper strain relief, type of box, and guarding, if needed.
