How many hours of fire barrier are required for nitrocellulose storage?

For nitrocellulose storage, the required fire barrier protection is set to ensure that the specific hazards associated with nitrocellulose, which is highly flammable and can produce dangerous combustion products, are adequately mitigated. The correct requirement is a 2-hour fire resistance rating for the storage area.

This requirement is based on the principles of fire safety that dictate how different materials should be managed based on their hazard classifications. Nitrocellulose storage areas must be enclosed with fire barriers that are capable of withstanding fire exposure for this specified length of time to help prevent the spread of fire to other parts of a building. Such measures are crucial for protecting life safety and maintaining structural integrity in the event of a fire.
