Generally, local codes and ordinances govern hoistway enclosure construction. When not in conflict with a local code requirement, the enclosure shall:
(1) Be built to a height of 84 in. above each floor, landing and adjacent stairway tread;
(2) Extend (adjacent to the counterweights) the full height of the floor and 8 in. beyond the counterweight raceway;
(3) Be constructed of either solid material or material with openings that will reject a 2 in. diameter ball;
(4) Be supported and braced so that it does not deflect more than 1 inch when subjected to a force of 100 lbs. applied perpendicular at any point;
(5) A full height hoistway enclosure is required only on the side(s) of the material lift for which the car is not equipped with a gate or enclosure.
