placement of electrical outlets in buildings with medical gases.

placement of electrical outlets in buildings with medical gases.

placement of electrical outlets in buildings with medical gases.

(OP)
Hey I'm new to the forum. A question was posed to me about medical gas nitrous oxide (anesthesia) being heavier than air and thus requiring electrical outlets to be installed higher than normal due to the flammibility potential. Anyone have any knowledge of this?

RE: placement of electrical outlets in buildings with medical gases.

Outlets in medical facilities are often at about waist level, but that may be more for convenience.

Oh, in any case, I was just in a dentist's office, and the outlets were along the floorboard.

RE: placement of electrical outlets in buildings with medical gases.

I don't think nitrous is used anymore. There are specific codes governing electrical installations in areas where flammable gases are used medically. For some gases, the resistivity of the floor is specified. For instance the floor must have a high enough resistance value to prevent electric shock by conduction, but must still have enough resistance to prevent the buildup of static charges. I forget the exact values ranges but the code did specify the method of measuring the resistance of the floor. Fortunately much safer gases have been developed.

Hi tknorr,

Welcome to eng-tips, glad to have you here.

One caution: Posting the same question in more than one forum causes confusion, as discussions expand without coordination. Please have a read through the forum policies at Forum Policies.

I'll repeat my answer from the other post, for the benefit of those here.

Nitrous isn't flammable. It can accelerate the burning of things, though, like an atmosphere of enriched oxygen.

White Paper - PLM and ERP: Their Respective Roles in Modern Manufacturing
Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each person’s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
White Paper - Medical Device Design Control
Medical device product development is a highly integrated and regulated process. Implementation of a requirements tracking solution requires attention to a variety of nuanced topics. When presented with the task of tracking the many concept relationships in a project of this type, the initial software solution of choice tends to be a two-dimensional text systems. Download Now
