For pits deeper than how many feet is a pit door required?

A pit door is required for elevator pits that are deeper than 12 feet. The rationale for this requirement is primarily based on safety considerations. A deeper pit presents a greater risk for individuals accessing the elevator area, such as maintenance personnel. Having a pit door helps prevent accidental falls into the pit, enhances overall safety during maintenance operations, and restricts unauthorized access. This safety measure ensures that anyone working around or in the vicinity of the elevator system is safeguarded from potential hazards associated with deeper pits, such as unexpected movements or falls.

The specified depth of 12 feet serves as a critical threshold for implementing additional safety measures, including the installation of a pit door, in order to mitigate risks and comply with regulations intended to protect workers and users alike.
