The relationship between the criteria for identifying major hazard sources and the list of hazardous chemicals
Thread Content
Suddenly a question arose: Are they substances identified as major hazard sources in the list of hazardous chemicals?
I’m not quite clear about what you mean: I wonder if you’re asking whether all substances listed in the hazardous chemicals catalog need to be identified as major hazard sources? Not necessarily: Only when the quantity of hazardous chemicals reaches a certain level does it constitute a major hazard source ；
The substances identified as major hazard sources are those listed in the catalog of hazardous chemicals; whether a substance constitutes a major hazard source depends on the amount of that substance
The classification of major hazardous sources involving hazardous chemicals is carried out using the substances listed in the catalog of hazardous chemicals. It involves calculating a ratio that is the sum of the ratios obtained by dividing the actual amount of each hazardous chemical present in a unit (on-site) by its critical value as specified in the \"Identification of Major Hazardous Sources of Hazardous Chemicals\" (GB18218-2014), with these ratios being adjusted using correction factors; this resulting value R is then used as the indicator for determining the level of the major hazardous source.
