Whenever construction or demolition work reaches a height greater than 75 feet (22 860 mm), at least one elevator meeting the requirements of Chapter 30, or a hoist meeting the requirements of Section 3318 shall be kept in readiness at all times for Fire Department use. The maximum distance between the highest accessible floor from a temporary elevator or hoist and the working deck of the building under construction or demolition shall be no more than 75 feet (22 860 mm) or 7 floors. In concrete construction, the working deck is the floor being formed.

If the travel of the hoist cannot be increased due to inclement weather, it shall be increased by the end of the next working day.
