① Fine powders of cellulose ethers can form explosive dust in the air, just like polysaccharides or sawdust.
② Similar to other organic polymers, dry non-ionic ethers release static electricity. When storing and processing cellulose ethers, general precautions for powdered organic polymers must be followed. Flammability is similar to cellulose.
③ Overflow of the solution will form a very slippery film, which makes it difficult for workshop operators to move.
