Current through Vol. 24-12, July 15, 2024
Rule 41. Sections
						3.7 and
						3.7.1 of the ASME A17.1 code is
						amended to read as follows:
3.7. A
					 machinery space outside the hoistway containing a hydraulic machine and an
					 elevator controller must be a machine room. The hydraulic machine must be
					 located in the hoistway or outside the hoistway in an elevator machine room.
					 Hydraulic machines being installed in the line of movement of an elevator car
					 or where an affected person is required to work in the line of movement of an
					 elevator car must be prohibited. The elevator controller must be accessible
					 only from a machine room, control room, or hoistway.
3.7.1. Hydraulic machines, control equipment,
					 sheaves, and other machinery may not be exposed to the weather. Machine room,
					 control room, and machinery-space enclosures must conform to the requirements
					 of sections
					 2.7.1 to 2.7.7 and 2.7.9 of the
					 ASME A17.1 code and the following:
Machine rooms and control rooms must be located at a
						hoistway landing associated with the equipment within the room. Elevator
						machine and control rooms may be located overhead, adjacent to, underneath the
						hoistway, or at a remote location. The entrance to the machine room or control
						room must be not more than 25 feet, clear unobstructed walking pathway from the
						elevator hoistway door. The distance from the machine room door to the hoistway
						door may be over 25 feet when the machine room is located directly above the
						hoistway in a conventional layout. Pit and hoistway access doors may not be for
						direct access between a hoistway enclosure and machine room or control room.
						Regardless of location, illumination of 19 fc, meaning foot candles, must be
						provided where controller and machinery work is to be performed.
Elevators installed without a machine room or control
						room must locate the required disconnecting means outside of the hoistway in a
						separate dedicated control space, readily accessible and adjacent to the
						control space that contains the control.
The disconnecting means must be in a single dedicated
						space or dedicated room
,
intended with or without full body entry,
						at a distance not to exceed 25 feet from the landing that contains the elevator
						control, inspection, or test panel. The disconnecting means must be secured so
						that only elevator journeyman and qualified personnel may gain access. If the
						controller is within an entrance assembly, signage must be placed in plain
						view, at or near the controller, and state the location of the disconnecting
						means.
Access to machine rooms, control rooms, machine spaces,
						or control spaces may not be through restrooms, lavatories, locker rooms, or
						associated vestibules. Where enclosed ceilings are required or
						provided
,
they must be of a solid type with no access panels. Drop
						type ceilings are not permitted. Machine rooms, control rooms, machinery
						spaces, and control spaces may not be used as a pass through or for access to
						other areas. Building access panels or doors are prohibited in these
						areas.
