Arizona Plumbing Practice Exam

Which of the following locations does not require fire sprinklers?

1. 3 ft x 8 ft linen closet

2. Basement storage area

3. Large open auditorium

4. Commercial kitchen

The correct answer is: 3 ft x 8 ft linen closet

The linen closet, measuring 3 ft x 8 ft, does not require fire sprinklers due to its limited size and the nature of its contents. In general, fire protection regulations exempt small spaces that do not pose a significant fire hazard. Linen closets are typically used to store bedding and towels, which, while they can catch fire, do not present the same level of risk as larger areas with more complex uses, such as a commercial kitchen or a large open auditorium. Moreover, fire codes are designed to prioritize the protection of larger spaces and areas where flammable materials are abundant or where a higher occupancy level creates a greater risk. Since the linen closet is a confined space with relatively low fire risk, it is not mandated to have fire sprinklers installed. This is why the choice pertaining to the linen closet is the most appropriate answer to the question about locations that do not require fire sprinklers.
