NEIEP Mechanics Practice Exam

For dumbwaiters with a rise of 25' or greater, what is the requirement for using hoist way access switches?

1. They are optional

2. They are required at terminal landings

3. They must be installed in the car

4. Their location is flexible

The correct answer is: They are required at terminal landings

In the case of dumbwaiters with a rise of 25 feet or greater, the requirement for hoist way access switches is that they must be installed at terminal landings. This ensures that operators can safely access the dumbwaiter and control its operation from the entry points of the hoistway. Terminal landing access switches are essential for safety as they allow for instant control of the dumbwaiter in case an emergency situation arises while someone is loading or unloading items. Ensuring that access switches are located at terminal landings fulfills safety regulations intended to protect users and maintain proper operational standards. The presence of these switches reduces the risks associated with potential malfunctions or unintended movement of the dumbwaiter, which is particularly important in taller installations where the height can contribute to the severity of accidents. The options indicating that the switches are optional, must be installed in the car, or that their location is flexible do not align with the established requirements for safety and operational integrity surrounding higher-rise dumbwaiters.
