Storage rooms exceeding how many square feet must be 1-hour rated?

The requirement for storage rooms to have a 1-hour fire rating is based on building codes and fire safety regulations, which are established to minimize risks associated with fire hazards. Specifically, the 1-hour rating applies to storage rooms that exceed 100 square feet. This regulation is in place to provide additional fire resistance to larger spaces, which typically hold more combustible materials, thereby reducing the potential for fire spread within a building.

Having a fire rating means that the structure can withstand fire exposure for a specified amount of time, allowing for safer evacuation and more time for fire response teams to manage and control the situation. For storage areas over 100 square feet, ensuring proper fire-rated construction is critical in protecting both the building and its occupants.

The lower thresholds for both 50 and 75 square feet do not necessitate a 1-hour fire rating, and 200 square feet is above the required threshold but does not specifically pinpoint the minimum requirement set by the codes. Understanding these thresholds is essential for compliance with safety regulations when planning and designing spaces within a facility.
