Hospital Grade Smoke Detectors

[eprice]

IMO 517.61(C)(2) does apply to dental offices treatment areas where nitrous oxide is used.

The definition of "Anesthetizing Location" is "Any area of a facility that has been designated to be used for the administration of any flammable or nonflammable inhalation anesthetic agent in the course of examination or treatment, including the use of such agents for relative analgesia"

The definition of "relative analgesia" is "A state of sedation and partial block of pain perception produced in a patient by the inhalation of concentrations of nitrous oxide insufficient to produce loss of consciousness (conscious sedation)".

If nitrous oxide is not used, then that section would not apply.

Just wanted to add, those definitions are found in 517.2

It doesn't and they aren't required in dental offices unless there is a critical care area with a procedure table in it.

However, some dental equipment has, as part of it's instructions, the requirement that it be plugged into a HG receptacle.

This is true but, that is not an NEC issue and unless it was noted on the plans it would not be part of a plan reveiw.

Quote the inspector, "110.3(B)"

This issue came up on the dentist office I am doing. It's a non-issue for me due to the fact HG receptacles were speced, but the inspector asked that either everything that was to go in the exam/xray rooms be in place for final inspection, or HG receps be installed.

John, I would put a coffee pot in the room and tell him that was it. IMO, anything that plugs into a receptacle is out of an EI's scope, and your inspector is making up his own rules.

Health care facilities can change equipment frequently so an inspector would have no idea of what is going to be plugged in at any given time.

As a matter of fact, some of the facilities I deal with don't even purchase all of the equipment until after the final. With that said, an inspector demanding something outside of the NEC requirements because of what he fantasizes may be installed is bogus.

Now, would I use HG receptacles in these locations for the "what if" possibilities, yes I would, but that would be my choice.

There is no such thing as a "Hospital Grade" smoke detector. All smoke detectors, connected to a fire panel are UL 268 listed. They are commonly installed in group I, B, and all other occupancies that require a fire alarm "System".

There are several manufacturers making smoke detectors that incorporate a "CO" sensor as one of the elements and do so to minimize false alarms. These detectors have a much higher cost the conventional UL 268 detectors however.
