Hydrochloric Acid NFPA 704 Diamond Sign: Health 3, Flammability 0, Instability 0
Post the correct NFPA 704 rating for hydrochloric acid, also sold as muriatic acid, on pool chemical rooms, acid storage areas, water treatment rooms and cleaning chemical stock. Hydrochloric acid carries a 3-0-0 rating: Health 3 (serious injury on short exposure, corrosive to skin, eyes and airways), Flammability 0 (does not burn), Instability 0 (stable). NFPA 704 does not define a corrosive symbol, but many facilities add COR in the white field. Confirm the rating against your supplier's Safety Data Sheet, Section 16.
The sign uses the standard NFPA 704 diamond with blue, red and yellow quadrants and a white special hazard field. Fire crews and inspectors read it the same way on every site.
