What is the maximum unlatching force for panic and fire hardware?

1. 15 pounds

2. 25 pounds

3. 10 pounds

4. 5 pounds

The correct answer is: 10 pounds

The correct answer is 15 pounds. According to the regulations regarding panic and fire hardware, the maximum unlatching force is designed to ensure that these essential safety devices are easily operable in emergency situations. In order to facilitate a quick and efficient exit, particularly during events such as fires or other emergencies, panic hardware must not require excessive force to operate. The 15-pound limit is a specific regulation meant to balance safety and accessibility, ensuring that individuals of all abilities can open the door quickly. This limit is set to provide clarity and consistency across installations, allowing for effective evacuation procedures in buildings. Choosing an option such as 10, 5, or 25 pounds would not align with established guidelines. While lower unlatching forces may enhance accessibility even further, they are not the standard requirement, and a higher threshold like 25 pounds could impede emergency egress and contradict safety regulations. Thus, understanding the significance of the maximum unlatching force helps in recognizing its role in maintaining safety compliance in building design and construction.
