What is the clear width measurement for door egress components?

The measurement of clear width for door egress components is critically important for ensuring safe and efficient evacuation during emergencies. The clear width is defined as the unobstructed width available for egress, and it is measured at the narrowest point of the egress component. This is vital because it ensures that the minimum passage width required for safe exit is maintained without any impediments.

When considering egress design, it is crucial to adhere to these standards to facilitate a smooth flow of individuals evacuating a space. If the clear width measurement were taken at a wider point rather than the narrowest, it could give a false sense of security about the adequacy of the passage, potentially leading to dangerous situations where an obstruction occurs.

By measuring at the narrowest point, safety professionals can ensure compliance with relevant codes and regulations, facilitating the safe egress of occupants during an emergency. This attention to the narrowest part of the doorway helps identify any elements that might limit egress and allows for appropriate measures to be taken to remedy those limitations.
