The company is currently applying for a work safety license, and I have some doubts: when checking the list of hazardous substances from 2015, many of the hazardous substances that were registered by the company in 2013 can no longer be found there. So I checked the 2002 hazardous chemicals catalog, but I couldn’t find any entries for substances such as abamectin, glyphosate, or butachlor. The products that are manufactured, such as wettable powders and aqueous solutions, were also not listed in the catalog. Emulsifiable concentrates, on the other hand, contain organic solvents; it is probably for this reason that they are classified as hazardous chemicals. Why aren’t the products that can’t be found in the catalog listed in the dangerous goods catalog? Is it because I didn’t check thoroughly, or is there another reason? I would appreciate it if experts could give me some guidance. Thank you
It can be searched using both the chemical name and CAS number; if neither the chemical name nor the CAS number matches, it is generally not considered a **chemical**. As for the powder forms, aqueous solutions, and emulsifiable concentrates you mentioned, it depends on what specific substances they are; for example, imidacloprid powder and imidacloprid emulsion are listed under entry number 402 “Imidacloprid” in the **Chemical Catalogue 2015 Edition**.
Flammability, explosiveness, and toxicity are the basic principles
Those not registered do not need to go through any procedures, but the operations should still be handled as if they were hazardous
This needs to be determined based on the **definition of chemicals; it is generally difficult for catalogs to list all substances
