Determination of fire hazard

Thread Content

Insecticide aerosols contain 40% butane and 58% kerosene, while foam sealants contain 18% butane and 80% chlorinated paraffins. What category do these two products fall into? The explanatory notes on page 188 of the Building Code refer to the Rules for the Transport of Dangerous Goods; according to those rules, the inner packaging specified in the Requirements for Packaging of Small Quantities of Dangerous Goods may have a capacity of up to 1 L, and such packaging is transported as ordinary goods, falling under Category 2. Does this correspond to Category B as mentioned in the Building Code? Are there any organizations that can prepare reports on fire hazard assessment? For the classification of physical hazards associated with chemicals, there is still no distinction between Category A and Category B. How do the Category A and Category B classifications mentioned in building codes correspond to the categories specified in documents such as the \"Classification and Labelling of Dangerous Goods\", the \"Catalogue of Hazardous Chemicals\", and the \"Hazardous Chemicals Classification Information Table\"? Is there an authoritative appraisal institution for assessment?
