Has a pungent irritating odor. Flash point varies from 122 to 141°F. Denser than water. The vapors are heavier than air and are highly irritating to the nose. Toxic if swallowed. Contact can cause severe injury to the skin accompanied by drying, cracking, and scaling. Used to make plastics, other chemicals, and fertilizers. Used as a preservative and a corrosion inhibitor. Rate of onset: Immediate Persistence: Hours Odor threshold: 1 ppm Source/use/other hazard: Disinfection/germicide; fungicide; textile; health care (tissue fixing).;Formaldehyde, solutions (formalin) (corrosive) appears as a colorless liquid with a pungent irritating odor.
