If you’re a downstream user–and I presume that’s why you’re asking the Q–you don’t have to prepare the SDS’ for the hazardous products you store, handle or use. Instead, you can and must get the SDS for each product from the manufacturer or distributor. THEY have the database, not to mention the legal obligation to prepare (and distribute) the SDS, not you. If I’m not understanding your Q, please rephrase and I’ll give it another shot. Thx. Glenn
