§ 405.34. Projections and recesses.
Projections or recesses for landing entrances, junction boxes and conduits for wiring, seating cart storage areas, orchestra areas and piano storage areas shall have the following protection:
(1) Metal bevel plates shall protect the underside and topside of projections and the underside of all recesses. The plates shall extend from the edge of the projection or recess to the wall. The beveled angle may not be less than 75° relative to a horizontal position. Instead of plates, the bevel surfaces may be made of concrete and troweled to a smooth finish. Pressure sensing strips meeting the requirements in paragraph (2) may be used instead of beveled plates.
(2) Pressure sensing strips shall be placed on the underside of the platform on sides where there is a projection or recessed opening and on an apron attached to the platform. Pressure sensing strips shall meet the following requirements:
(i) A strip shall be interconnected to the operating and controlling circuit of the elevator.
(ii) A strip shall detect an obstruction that exerts a force of 5 pounds or greater per square inch.
(iii) The elevator shall immediately stop and automatically reverse direction for travel of 24 inches when a strip detects an obstruction. The pressure strips may automatically reset once the elevator has stopped its reverse travel.
