Dumbwaiters Can Kill: Interlocks on Doors Prevent Tragedy

• Description:
  Older buildings may have dumbwaiters that don't have interlocks to prevent serious, even fatal injuries. No one should be allowed to operate a dumbwaiter until interlocks are installed and working properly. Why does a dumbwaiter need interlocks? All dumbwaiters must have functioning interlocks on doors, as specified by the American Society of Mechanical Engineers (ASME E A17.3-2011). The interlocks prevent a dumbwaiter from operating until all doors are closed. They also prevent doors from opening until the cart is in position for loading or unloading. Without interlocks, people are at risk of falling down the dumbwaiter shaft or being crushed by the cart. How can I tell if a dumbwaiter does not have interlocks? Can you make the dumbwaiter cart travel up or down when any access door is open? Can you open an access door when the dumbwaiter cart is not at your floor? If you answered yes to either of these questions then your dumbwaiter does not have a functioning interlock. Stop using the dumbwaiter immediately and contact an elevator service company.
