According to NFPA 230: Standard for the Fire Protection of Storage, 2015 Edition, building codes should limit the size of an unsprinklered facility used for the processing and storage of Municipal Solid Waste (MSW) built of type V construction to 7,500 ft2 (697 m2). This is based on the assumption that the MSW has a heat release rate of 18,000 Btu/ft2-min (200 kW/m2) and a fire growth rate of 0.046 min-1.Type V construction is defined as a type of construction in which the structural elements, exterior walls, and interior walls are of any materials permitted by the code123

Cellulose nitrate products begin to decompose at about 300 °F (150 °C). This is the temperature at which the nitrate ester bonds start to break down and release nitric acid, which further catalyzes the decomposition. The decomposition temperature depends on the nitrogen content, the stabilizers, and the external heating rate of the cellulose nitrate.Higher nitrogen content, lower stabilizer concentration, and faster heating rate lower the decomposition temperature and increase the risk of thermal runaway.
