GFCI In Laboratories

[204]

Are GFCIs recommended around laboratory sinks? I read the NEC as such. The sink in question is at the front of a lab bench and the outlets are on either side of the sink, around a corner (a 90 degree angle from the sink), but within 6 feet of the sink. Our facilities staff says that since the outlet is at a 90 degree angle from the sink, the outlet does not need protection, as the employee would have to leave the sink to reach the outlet. Is this correct?

Where does the six feet rule for GFCI protected outlets come from? Is this related to the standard extension cord length, or does it have something to do with the expected splash distance from the sink?

Also, why does an outlet need GFCI protection to begin with? Is is due to the potential of an electrical applicance coming in contact with the water, or is to due to the potential for water splashing on the appliance or into the outlet during use?

Sorry if these questions sound simple, but electrical safety is not my expertise.

Thanks in advance for your responses.

No NEC requirement for GFCIs at laboratory sinks.

The only place there is a "6' rule" for GFCIs is a dwelling unit wet bar sink.

There is also no reason you can not choose to add GFCIs near these laboratory sinks for added personal protection.

Combine a wet environment, proximity of grounded metal surfaces (the plumbing fixtures) electrical appliances and you have a situation that in my opinion is much more likely to pose a shock hazard then using an outlet in your living room for example.

It has been shown that in an industrial or commercial environment the wet areas are safe due to assured grounding. It is where bathrooms and kitchens are encountered that problems develop. Therefore, all bathrooms and kitchens now require GFCI protection but laboratories and similar areas do not.
