What is the maximum unlatching force required for doors?

1. 10 pounds

2. 15 pounds

3. 20 pounds

4. 25 pounds

The correct answer is: 15 pounds

The maximum unlatching force required for doors is critical in ensuring that doors can be easily operated while still providing security and accessibility. The requirement of 15 pounds as the maximum force aligns with the standards set forth in the guidelines for accessibility, such as those from the Americans with Disabilities Act (ADA). This limit is intended to facilitate ease of use for all individuals, including those with physical disabilities who may have difficulty applying greater force. Setting the maximum unlatching force at 15 pounds ensures that doors can be opened without excessive effort, helping to meet safety compliance and accessibility regulations. This weight ensures that individuals using wheelchairs or with limited upper body strength can navigate spaces safely and effectively. Higher unlatching force limits, such as 20 or 25 pounds, could pose challenges, particularly in emergency situations where quick access is required. Therefore, 15 pounds reflects a balance between safety and accessibility, emphasizing that doors should be functional for everyone.
