ICC Commercial Building Inspector Practice Test

In a fully sprinklered building, what is the allowed limit for storing Class IIIA combustible liquids?

1. 440 pounds

2. 660 pounds

3. 880 pounds

4. 1100 pounds

The correct answer is: 660 pounds

In a fully sprinklered building, the allowed limit for storing Class IIIA combustible liquids is set at 660 pounds. This limit is established according to the National Fire Protection Association (NFPA) guidelines and local building codes, which consider the increased safety measures provided by a sprinkler system. The rationale behind allowing a higher quantity of combustible liquids in fully sprinklered buildings relates to the enhanced fire suppression capabilities that such systems offer. Sprinklers can effectively control and mitigate fire hazards associated with these types of liquids, which are often defined by their flash point and combustibility. The storage of Class IIIA liquids, which includes products like certain oils and fuels, requires careful consideration of fire safety measures. In buildings equipped with a functioning sprinkler system, the risk is significantly reduced, allowing for the higher storage limit compared to non-sprinklered facilities. This balance of risk management and operational practicality is key in ensuring safety and compliance with fire codes.
