Membrane structures with a life expectancy of fewer than 180 days are addressed by which codes?

• A. Building Codes
• B. Fire Codes
• C. Electrical Codes
• D. Mechanical Codes

Answer: (B)

Membrane structures that are intended to be temporary are governed by fire codes because the primary concern is life safety and fire protection during a short-term use. When a fabric tent or membrane has a life expectancy under 180 days, the fire code provides the specific requirements for flame resistance of materials, occupancy limits, means of egress, fire protection measures (such as extinguishers or sprinkler considerations where applicable), fire department access, and required distances from other structures. The building code focuses on permanent structures and long-term occupancy, so for short-lived installations the fire code is the controlling document. If the structure were to remain in place for a longer period (over 180 days), it would typically fall under building code provisions instead.
