Is the sulfur fire classified as Class B or Class C? Thank you!
Sulfur is a flammable solid that does not belong to Class A, and its fire hazard is classified as Class B. It is included in the examples of classification for the interpretation of Article 3.1.3 of the Building Code GB50016-2014.
As a supplementary note, for industrially shaped sulfur with a particle size of 2 mm or more (such as in spherical, granular, lumpy, ingot, or flake form), according to the findings of the research on \"Key Technologies for the Storage and Fire Protection of Bulk Sulfur\" carried out jointly by the Tianjin Fire Research Institute of the Ministry of Public Security, Sinopec Engineering Construction Company, and other organizations, its fire hazard classification is that of Class C solids. Also from the Code for Fire Protection Design of Buildings GB50016-2014
