According to disabled-access regulations, what is the maximum pressure required to open fire doors?

The maximum pressure required to open fire doors, as stipulated by disabled-access regulations, is 15 pounds. This standard ensures that all individuals, including those with disabilities, can operate fire doors without excessive effort. The design of these regulations takes into account the need for ease of movement during emergencies, where rapid egress may be necessary. Setting the pressure limit at 15 pounds allows for a balance between maintaining the door's functionality as a fire barrier and ensuring accessibility for all users.

Fire doors must be equipped with a mechanism that allows them to close automatically, yet they should not require excessive force to open, which would be a barrier for individuals who may have limited strength or mobility. Hence, adhering to the 15-pound maximum aligns with ensuring compliance with accessibility standards and maintaining the safety purpose of fire doors. Other values, such as 5, 10, or 20 pounds, do not meet the established regulations for accessibility and safety.
