ICC Commercial Building Inspector Practice Test

Which category of hazardous materials requires barricade construction for explosion control?

1. Inorganic acids

2. Flammable solids

3. Organic peroxides

4. Radioactive materials

The correct answer is: Organic peroxides

Organic peroxides require barricade construction for explosion control due to their highly reactive nature and potential to undergo violent decomposition or combustion. When exposed to heat, shock, or friction, organic peroxides can lead to explosive reactions, making it crucial to implement safety measures that include physical barriers to contain blasts or prevent the spread of fire. In many industrial settings, the use of barricades helps to protect adjacent structures, personnel, and equipment from the risks associated with these materials' instability. Proper barricade construction is part of an overall safety strategy that includes labeling, proper storage, and adhering to regulations that govern the handling of hazardous substances. While other hazardous materials, such as flammable solids, inorganic acids, and radioactive materials, pose significant risks and require careful handling, their specific safety measures differ. In contrast to organic peroxides, the focus for flammable solids might be on preventing ignition rather than controlling potential explosions.
