ICC Permit Technician Practice Exam

1. 18

2. 24

3. 20

4. 30

The correct answer is: 30

The requirement for a minimum of 30 inches of clear headroom at or above the access opening to the attic space is grounded in ensuring safety and accessibility. This height allows personnel to enter and navigate comfortably within the attic without the risk of hitting their heads, which is particularly important for tasks such as inspections, maintenance, or any necessary repairs. This regulation promotes safety by minimizing potential hazards associated with limited headroom, such as unexpected injuries due to low ceilings. Additionally, a height of 30 inches creates adequate space for individuals to move freely, handle equipment, and perform work without feeling cramped or restricted. Other heights listed in the choices, while they may offer some level of accessibility, do not provide the same degree of safety and practicality for working within attic spaces. Thus, the 30-inch minimum is established to strike a balance between accessibility and safety in these often confined and critical areas of a building.
