Which of the following is an example of a hazardous occupancy?

A chemical storage facility qualifies as a hazardous occupancy due to the presence of chemicals that can pose significant risks to health and safety. Such facilities often contain flammable, corrosive, or toxic substances that can lead to fires, explosions, or chemical spills if not managed properly. This classification aligns with fire safety regulations, which categorize occupancies based on the nature and extent of hazards they present.

In contrast, a school classroom, a hospital waiting room, and a residential apartment are typically not classified as hazardous occupancies because they do not involve the same level of risk associated with chemical handling or storage. While these environments can still have safety concerns, they do not possess the significant dangers inherent in the processing or storing of hazardous materials found in a chemical storage facility. Understanding these classifications is essential for implementing appropriate fire safety measures and emergency response procedures tailored to the specific risks associated with different types of occupancies.
