ICC Commercial Building Inspector Practice Test

What is the cubic footage threshold for requiring an automatic sprinkler system in tire storage areas?

1. 15,000 cubic feet

2. 20,000 cubic feet

3. 25,000 cubic feet

4. 30,000 cubic feet

The correct answer is: 20,000 cubic feet

The threshold for requiring an automatic sprinkler system in tire storage areas is established based on life safety and property protection considerations, given the unique fire hazards associated with tire storage. In this context, the correct threshold is 20,000 cubic feet, which aligns with safety codes and standards that address the combustible nature of tires. When storage areas exceed this cubic footage, the risk of fire increases significantly, prompting the need for an automatic sprinkler system to help control and extinguish potential fires before they can spread. Tire fires can produce high levels of heat and toxic smoke, making early suppression crucial for safety. Thus, understanding this threshold is essential for inspectors, as it directly informs compliance with building codes aimed at mitigating fire risks in commercial settings. In contrast, thresholds set at lower measurements may not adequately address the hazards posed by larger quantities of tires, which can escalate swiftly in the event of a fire. Hence, this specific cubic footage requirement plays a pivotal role in ensuring that adequate fire protection measures are in place.
