What is the maximum force allowed for an automatic door to begin moving manually?

The correct answer is based on accessibility standards that aim to ensure that automatic doors can be operated manually with minimal effort. Specifically, the maximum force allowed to initiate the movement of an automatic door manually is consistently set at 50 pounds. This limit is established to accommodate individuals with disabilities or limited strength, ensuring that the doors are not overly heavy or difficult to open when necessary.

By stipulating this maximum force requirement, regulations promote safety and accessibility in commercial buildings, allowing all individuals, including those using mobility aids, to navigate through doorways without undue struggle. Consequently, designing automatic doors to meet this standard is critical for compliance with accessibility laws such as the Americans with Disabilities Act (ADA).

Overall, understanding the maximum force requirements for manual operation of automatic doors is vital for inspectors to ensure that buildings adhere to codes designed to create inclusive and accessible environments.
