When panic hardware is required, occupants should be able to open the door by applying a force of not more than how many pounds?

• A. 5
• B. 10
• C. 15
• D. 20

Answer: (C)

Panic hardware is meant to let people escape quickly in an emergency, even if they’re dealing with gloves, fatigue, or bulky clothing. To ensure this, the force needed to open the door from the inside is kept very small and reliable. The standard specifies that you should be able to operate the push bar or handle with a maximum of 15 pounds of horizontal force. This strikes a balance: it’s light enough for rapid egress by most occupants, but not so light that minor bumps or accidental contact could cause the door to open unexpectedly. Choosing a force significantly higher would hinder swift escape, while forces well below 15 pounds aren’t necessary for practical operation under real conditions.
