This chapter does not apply to locations that can only be accessible through ladders, catwalks, crawl spaces, freight elevators, or extremely tight tunnels. These locations are required by law to have an emergency exit. In addition, this chapter does not apply to hotel rooms, apartments, or other lodging facilities. These locations are required by law to have working smoke alarms and fire extinguishers in each room. Elevators must meet all requirements of the Michigan Building Code to be considered safe. The Building Code requires elevators to have fire doors that close automatically in case of a fire, resistive wires to prevent electric shock, and two way voice communication between the cab and the floor to allow passengers to hear noises outside the elevator if it stops between floors. The Building Code also requires that elevators have functioning lights and sound-emitting devices to warn people when the elevator is about to arrive at a floor. The code further requires that elevators be maintained daily by a licensed mechanic who is aware of their electrical systems. People who use elevators every day should take note of how old they are. An old elevator may not be as safe as one that is new.
