The correct answer is that a 2-hour fire-rated construction is typically required to separate boiler rooms, incinerator rooms, storage rooms over 100 square feet, paint shops, and maintenance shops. This level of fire rating helps to mitigate the potential risk associated with these specific types of spaces, which often contain flammable materials or equipment that could contribute to fire hazards.

The 2-hour fire rating is significant because it provides a substantial amount of time for occupants to evacuate safely in the event of a fire and allows emergency responders the opportunity to control and suppress the fire before it spreads to adjacent areas. This level of construction ensures that walls, floors, and ceilings that separate these functional spaces are robust enough to withstand a fire for an extended period.

Understanding the importance of fire ratings is critical in fire protection design, as it directly relates to life safety, property protection, and compliance with building codes and regulations.
