Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Z-1 Table -- 1 ppm, 3 mg/m3 TWA

Construction Industry: 29 CFR 1926.55 Appendix A -- 1 ppm, 3 mg/m3 TWA

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL):1 ppm, 3 mg/m3 TWA; 2 ppm, 6 mg/m3 STEL

Health Factors

Carcinogenic Classification:

Environmental Protection Agency (EPA): Group C, possible human carcinogen

International Agency for Research on Cancer (IARC): Group 3, not classifiable as to its carcinogenecity to humans [381 KB PDF, 171 pages]

NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 250 ppm

Potential Symptoms: Irritation of eyes, skin, nose, mucous membrane; lacrimation, sneezing, cough, sore throat, labored breathing, pulmonary edema (may be delayed); headache, dizziness, weakness; tingling sensation, coldness, numbness in hands and feet; eye redness, pain, blurred vision; in animals: liver, kidney injury; INGES. ACUTE: Burning sensation, abdominal pain, vomiting.

Health Effects: Irritation- Eye, Nose, Throat---Marked (HE14); Polyneuropathy (HE7); Liver damage (HE3); Mutagen (HE2).

Affected Organs: Eyes, skin, respiratory system, peripheral nervous system, liver, kidneys.


  1. Vapor/air mixtures of Allyl chloride may be explosive.
  2. The major urinary metabolite, 3-hydroxypropylmercapturic acid, has been studied as a biomarker for occupational exposure to Allyl chloride, and an 8-hour biological exposure index of 352 µg/gram creatinine has been proposed. However, garlic consumption may interfere with an accurate determination of occupational exposure.
  3. This metabolite is not specific for Allyl chloride, as it may also be produced from allyl alcohol, allyl formate (and other allyl esters), allyl nitrate, and acrolein.
  4. Mechanistic studies of neurochemical changes in rats gavaged with Allyl chloride in corn oil (200 mg/kg, 3 times/week for 12 weeks) indicated toxic effects in the CNS as well as in the peripheral nervous system.
