What is the maximum allowable pressure for a latch on an emergency egress door?

• A. 15 psf
• B. 30 psf
• C. 5 psf
• D. 10 psf

Answer: (A)

The maximum allowable pressure for a latch on an emergency egress door is established to ensure that the door can be easily opened under pressure without compromising safety during an emergency. A limit of 15 pounds per square foot (psf) is considered sufficient to maintain the security of the latch while still permitting swift access when necessary. This ensures that individuals can exit quickly without struggling against excessive pressure that could cause delays or create hazards. Considering the options, the chosen answer aligns with safety standards that aim to balance security and accessibility in emergency situations. The other values represent either standards that are too low, potentially compromising security, or too high, which would impede the ability to open the door in urgent circumstances. Understanding these factors is crucial in designing emergency egress systems that are both safe and effective.
