Turnstiles that exceed what height should be treated as revolving doors?

The height that determines when turnstiles should be treated as revolving doors is 39 inches. This measurement is important because it relates to accessibility and safety standards. When a turnstile exceeds this height, it poses challenges for individuals with disabilities, particularly those who may use wheelchairs or other mobility aids.

By classifying turnstiles above 39 inches as revolving doors, building codes and fire safety standards emphasize the need for ease of access in emergency evacuations and regular use. Revolving doors are designed to manage foot traffic while also offering better airlock capabilities, which can be beneficial for energy efficiency and controlling indoor climates.

Adhering to this height requirement helps ensure compliance with the Americans with Disabilities Act (ADA) and allows for a safer environment where everyone can evacuate in a timely manner without being impeded by height restrictions that might be imposed by regular turnstiles.
