Help: Question: What is the fire hazard category of a 10% sodium hypochlorite solution? Is it Category E or Category B? Thank you!
The fire hazard category of a 10% sodium hypochlorite solution is Class V. Sodium hypochlorite is primarily an oxidizing substance; it can assist in combustion but is not flammable itself. .
According to building codes, due to its strong oxidizing properties, does it fall into Category B?
According to the interpretation of Article 3.1.3 of the Building Code GB50016 (page 188, point 2), the classification of Class B storage substances is primarily based on the characteristics of Class II flammable solids, combustible materials, oxidizers, combustion-supporting gases, and self-igniting substances as defined in China’s Rules for the Transport of Dangerous Goods； According to Article 349, Item 1791 of JT/T617.3-2018, hypochlorite solutions are classified as Category 8 corrosive substances. In summary, sodium hypochlorite solution does not belong to the oxidizers classified as Category A or B for fires under building codes.
