CODE UPDATE
Update #2 - Identification of Equipment (2.29.1)
In buildings with more than one elevator, [the 1996 code read "When the machinery of more than one elevator is in a hoistway or machine room,..."] each elevator in the building shall be assigned a unique alphabetical or numerical identification, a minimum of 50 mm (2 in.) in height [the 1996 code read 1 1/2 in. (38 mm)] unless otherwise specified. The identification shall be painted on, engraved, or securely attached to
1 - the driving machine
2 - main line disconnect switch
3 - the crosshead, or where there is no crosshead, the car frame, such that it is visible from the top of the car
4 - the car operating panel, minimum of 13 mm (0.5 in.) in height
5 - MG set [New]
6 - controller [New]
7 - selector [New]
8 - governor [New]
9 - adjacent to or on every elevator entrance at the designated level, a minimum of 75 mm (3 in.) in height [New]
Please Note: As you can see 5 new locations have been added to the list since the 1996 code. Some companies also paint the ID on the platform guard (car apron) which makes it easy to positively identify which elevator you are working on if you have the car accessed up out of the pit. However, it is permissible to access the car as high as the point where the bottom of the platform guard is even with the hoistway entrance header so the number might not be visible. (See 2.12.7.3.6) I always recommend that one device in the pit be marked with the identifying number as well. A walk-in pit with several elevators could become confusing without identifying markings.
