On hydraulic elevators, design clear access for hydraulic oil line between machine
room and hoistway. Hydraulic oil lines shall remain in or under conditioned space
from end to end and remain within the building footprint. Provide straight pipe run in
PVC pipe sleeves for oil spill containment of all buried hydraulic lines between
machine room and the hoistway.
On hydraulic elevators, sprinkler protection is required at the top of the hoistway when
the hydraulic cylinder or supply piping extends above the second finished floor
elevation. Refer to Chapter 7, "Fire Protection Elevator Design Guide" for
Coordinate sprinkler and smoke detector requirements with Fire Protection Engineer
and Electrical Engineer. Confirm smoke detectors are shown on fire alarm plans and
For interior cab dimensions of new elevators being installed in an existing hoistway,
insure that the design meets the requirements of ASME A17.1. (Rule 201, Capacity
and Loading). Passenger elevators frequently require greater capacity (pound per
square foot (kilogram per square meter)) than freight elevators.
Indicate 2-hour fire rating for floor, walls, and top of hoistway (when terminated below
roof level) construction.
If building roof construction is combustible: Item a. below is considered good practice
for 2-hour rated hoistways that terminate at the roof level, item b. below is required for
2-hour rated hoistways that terminate below the roof level.
a. Extend 2 hour rated hoistway through the roof and terminate the top of the hoistway
at least 3'-0" (914 mm) above the combustible roof with a 2-hour enclosure, or
b. Terminate the 2-hour rated hoistway below the roof level with a 2-hour rated
If building roof construction is noncombustible: comply with one of the following
requirements for top termination of the 2 hour rated hoistway.
a. Extend 2 hour rated hoistway construction to the underside of the roof deck or slab.
Seal wall construction tight to deck or slab and roof construction becomes hoistway
b. Terminate the 2-hour rated hoistway below the rated roof level with a 2-hour rated
