What is the maximum height for the access opening to fire escapes from the floor?

The maximum height for the access opening to fire escapes from the floor is specified to ensure that individuals can quickly and safely access these critical exits in an emergency situation. An access height of 12 inches strikes a balance between safety and accessibility.

This height allows for ease of use by individuals of various sizes, including those who may have mobility challenges or may be carrying items while evacuating. Additionally, a 12-inch height ensures that the opening is unobstructed while also providing a direct route to the fire escape.

If the access opening were higher, such as 15 inches, it could pose a risk during a fire emergency where every second counts, as individuals might struggle to reach it quickly. Similarly, lower openings, like 6 or 10 inches, would hinder quick access and could lead to accidents or injuries during an evacuation. Thus, the 12-inch maximum height is established as a standard for safe and efficient egress from buildings in fire emergencies.
