Section 296-96-02450. Can pipes and ducts be installed above a machine room?

Latest version.

Electric conduit and ducts may be installed in the upper space ("upper space" is defined as the space above the fire-rated ceiling) of the elevator machine room as long as they are installed above the required seven-foot clearance and they do not interfere with the elevator equipment which also must be installed to allow a seven-foot clear head room.

(1) Straight through runs of electrical conduit without junction boxes can be installed in this space.

(2) Pipes and ducts conveying gases, vapor, or liquids may be installed in the space above the machine room provided they are encased in a noncombustible secondary pipe without joints, or a moisture barrier without penetration.

EXCEPTION:
Residential elevators are exempt from this section.
