Safety Code for Existing Elevators and Escalators
(For designing changes to existing Elevator/Escalator Systems)
NFGS - 14210 - NAVFAC Guide Specifications Section 14210,
"Electric Traction Elevators"
NFGS - 14240 - NAVFAC Guide Specifications Section 14240,
"Hydraulic Elevators"
NFPA 70 - National Electric Code (NEC)
NFPA 80 - Fire Door and Fire Windows
Uniform Building Code
UFAS -  Uniform Federal Accessibility Standards
4-1.2 The requirements and guidance provided in this Mechanical Elevator Design Guide are
applicable to both continental United States and overseas projects, however the
technical/commercial reference standards (ASME, NEC, ADAAG) listed in this
document will be different in Europe.
4-1.3 Sprinkler protection shall not be provided for elevators hoistway, pit, and machine rooms
of Italian construction projects. Italian law does not allow sprinklers in these areas.
Machine Room
4-2.1 Indicate ventilation as required by ASME A 17.1 (Rule 101.5, Lighting and Ventilation of
Machine Rooms and Machinery Spaces). Provide heating, ventilating, and air-
conditioning to elevator machine room to maintain temperature limits between 50 to 90
degrees F (10 to 32 degrees C) as recommended by elevator manufacturers. Air
conditioning is required in most conditions; gravity ventilation is not acceptable.
Coordinate with Electrical Engineer. Provide emergency power for machine room
cooling/ventilating equipment, if the elevator is on emergency power circuit
