The minimum corridor width for Group E with an occupant load of 100 or more is _____ inches.

• A. 72
• B. 80
• C. 84
• D. 96

Answer: (A)

The minimum corridor width for a Group E occupancy, which includes educational facilities, is established to ensure safe and efficient egress for occupants, particularly in emergency situations. For an occupant load of 100 or more, the code specifies that the width must be a minimum of 72 inches. This requirement accommodates the need for a quick and unobstructed flow of people, as well as compliance with accessibility standards.

In comparison, the other options exceed this minimum requirement, reflecting widths that may be beneficial in certain contexts but are not mandated by code for this specific situation. The intent of the minimum width is to provide basic safety and accessibility measures while still being practical for average building designs. Thus, while a corridor wider than 72 inches may offer advantages, it is the 72-inch minimum that aligns precisely with the established code for an occupant load of 100 or more.
