Main indicators for evaluating the fire hazard of substances
Thread Content
1. What are the main indicators used to evaluate the fire hazard of gases, liquids, and solids? Gases: explosion limit, autoignition temperature. Liquids: flash point. Solids: melting point, ignition temperature. 2. In a Class V automobile assembly plant where there is no limit on the maximum allowable floor area per fire compartment, if the area occupied by the spraying section is less than 10% of the total area of the assembly plant, its production category is classified as ( ) category. Class V
The explosion limit and autoignition temperature are the main indicators for assessing the fire hazard of gases. The flash point is a key indicator for assessing the fire hazard of liquids. For the vast majority of combustible solids, melting point and ignition point are the main parameters used to assess their fire hazard.
Gases: explosion limit, autoignition point. Liquids: flash point. Solids: melting point, ignition point. Pentane series
