View Answer

Answer: B

Explanation:

A machine shop is typically considered an Ordinary Hazard Group 1 occupancy due to the moderate level of fire load, including the presence of combustible materials, machinery, and processes that produce sparks or hot metal. This classification guides the design and installation of sprinkler systems to address the specific fire risks associated with such environments.

Reference: NFPA 13’s occupancy hazard classifications, which help determine the appropriate sprinkler system design criteria based on the expected fire load and combustibility of materials present.
