Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amendment provides clarity and
				  consistency to sections of the existing rules referencing the proposed updated
				  code adoption in 11 CSR 40-5.050.
(1) In a political subdivision or
				municipality that had adopted an edition of ASME A17.1 code, elevator equipment
				shall conform to the code requirements adopted and enforced at the time the
				elevator equipment was installed. The following standards apply to all existing
				elevator equipment installed prior to July 1, 1999 as provided in
				11 CSR
				40-5.060. Any installation which is in compliance with
				the latest ASME A17.1 version adopted and amended by the Elevator Safety Board,
				unless as exempted by 701.359, RSMo shall be considered to be in compliance
				with 11 CSR 40-5.065.
(A) Hoistways.
1. Each passenger elevator hoistway landing
				shall be protected with a door or gate. The door or gate shall be of solid
				construction and shall guard the entire entrance.
2. All automatic passenger elevators with
				power doors shall have non-vision panels on hoistway doors.
3. Each hoistway landing in any elevator
				hoistway shall be continuously provided with a properly working door or
				gate.
4. Where freight elevator
				hoistway doors or gates are of open or lattice construction they shall be at
				least six feet (6') high and shall come within two inches (2") of the floor
				when closed. Gates shall be constructed as to reject a ball two inches (2") in
				diameter. They shall withstand a force of two hundred fifty (250) pounds
				pressure applied in the center of the gate without breaking or forcing it out
				of its guides.
5. Manually operated
				bi-parting entrances of elevators which can be operated from the landings shall
				be provided with pull straps on the inside and outside of the upper panel where
				the lower edge of the upper panel is more than six feet six inches (6'6") above
				the landing when the panel is in the fully opened position.
6. Each hoistway door or gate shall be
				provided with interlocks designed to prevent the car from moving unless the
				doors or gates are closed. Where doors or gates do not lock when closed they
				shall lock when the elevator is not more than twelve inches (12") away from the
				floor. Passenger elevator hoistway doors shall be closed and locked before the
				car leaves the floor.
7. All
				hoistway-door interlocks shall be of the hoistway unit type.
8. Automatic fire doors shall not lock any
				landing opening in the hoistway enclosure from the hoistway side nor lock any
				exit leading from any hoistway landing to the outside of the
				building.
9. Emergency keys for
				hoistway doors and service keys shall be kept readily accessible to authorized
				persons.
10. Access means shall be
				provided at one (1) upper landing to permit access to the top of the car, and
				at the lowest landing if this landing is the normal point of access to the
				pit.
11. Each hoistway door or
				gate, which is counterweighted, shall have its weights enclosed in a box-type
				guide or run in metal guides. The bottom of the guides or boxes shall be so
				constructed as to retain the counterweight if the counterweight suspension
				means breaks.
12. Hoistways
				containing freight elevators shall be fully enclosed. Enclosures shall be
				unperforated to a height of six feet (6') above each floor or landing and above
				the treads of adjacent stairways. Unperforated enclosures shall be so supported
				and braced as to deflect not over one inch (1") when subjected to a force of
				one hundred (100) pounds applied horizontally to any point. Open work enclosure
				may be used above the six-foot (6') level and shall reject a ball two inches
				(2") in diameter.
13. Hoistways
				containing passenger elevators shall be fully enclosed and the enclosure shall
				be of solid construction to its full height.
14. Except where vertical opening bi-parting
				doors are provided, all elevators provided with automatic leveling, inching, or
				teasing devices and where the landing sills project within the hoistway, shall
				be equipped with a bevel on the underside of the landing sill. Bevels shall be
				constructed of smooth concrete or not less than sixteen (16) gauge metal
				securely fastened to the hoistway entrance. Bevels shall extend the full depth
				of the leveling zone plus three inches (3").
15. Every hoistway window opening seven (7)
				stories or less on an outside wall above a thoroughfare and every such window
				three (3) stories or less above a roof of the building or of an adjacent
				building shall be guarded to prevent entrance by fire or emergency rescue
				persons. Each such window shall be marked "hoistway" in a readily visible
				manner.
16. All electrical wiring
				in the hoistway shall be enclosed in metal conduit, flexible conduit or metal
				raceway or be in compliance with NFPA 70, National Electric Code.
17. No pipes conveying liquids, gases, or
				vapors shall be located in a hoistway. Exception: branch lines for sprinkler
				system and low pressure steam lines for heating.
