Calcium Hypochlorite Fire Hazards
Thread Content
Please tell me: 1 Page 132 of GB50016-2006 (the fifth sub-item of the explanation of Article 3.1.1) is given: Calcium hypochlorite factory belongs to Category A production ； At the same time, page 139 (the second sub-item of the explanation of Article 3.1.2) is given: Bleaching powder belongs to Category B items. If there is a contradiction, how to explain it? 2 Check the calcium hypochlorite MSDS, "Calcium hypochlorite, also known as bleaching powder, will cause combustion when exposed to water or humid air. * * (baozha). ”Can it be judged that calcium hypochlorite belongs to GB50016 Class A, Item 4 (but it should not produce flammable gas)? 3 Sodium hypochlorite will cause combustion when exposed to water or humid air. * * What is the mechanism of (baozha)? Are the electrical instruments in its workshops considered explosion-proof? Thank you and look forward to your answers. (The chlor-alkali version has posted a query, but no results have been obtained, so it will be continued in this version. )
I only have the GB50016-2014 version in hand, and I can’t find the page you mentioned, but I can still tell you that the specifications are not inconsistent. Sodium hypochlorite is a Class A fire hazard material in the production workshop, but it is a Class B fire hazard material in the warehouse. There are many such situations, such as: Flour belongs to Category B in the processing workshop and Category C in the warehouse.
