Acetic Acid - Chemical Safety Facts
网页2022年10月14日 · Acetic acid has an OSHA permissible exposure limit (PEL) of 10 parts per million (ppm) over an 8-hour work shift. Symptoms of exposure to acetic acid vapors at that level can include eye, nose and throat irritation.
Acetic acid - IDLH | NIOSH | CDC - Centers for Disease Control …
网页The revised IDLH for acetic acid is 50 ppm based on acute inhalation toxicity data in humans.
1988 OSHA PEL Project - Acetic Acid | NIOSH | CDC
网页2011年9月28日 · CAS: 64-19-7; Chemical Formula: CH 3 COOH. The former OSHA PEL for acetic acid was a 10-ppm 8-hour TWA. OSHA proposed to retain the TWA limit and to supplement it with a 15-ppm STEL, based on the acute irritant properties of acetic acid. These limits are consistent with the ACGIH recommended TLVs (1986/Ex. 1-3).
网页Inhaling Acetic Acid can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency. Repeated exposure can cause thickening and cracking of the skin. Workplace Exposure Limits OSHA: The legal airborne permissible exposure limit (PEL) is 10 ppm averaged over an 8-hour workshift.

网页Acetic acid is a severe skin, eye and mucous membrane irritant. As an eye irritant it can cause burns, lachrymation, and conjunctivitis. Skin exposure can cause burns. Mucous membrane exposure results in burns and bleeding from ulcerations, along with nausea, vomiting and diarrhea. 1.1.3 Workplace exposure3,4.
