Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Z-1 Table -- 5 ppm, 19 mg/m3 TWA; Skin

Construction Industry: 29 CFR 1926.55 Appendix A -- 5 ppm, 19 mg/m3 TWA; Skin

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 5 ppm, 19 mg/m3 TWA; Skin

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 2 ppm, 7.6 mg/m3 TWA; Skin; Appendix A3, Confirmed Animal Carcinogen with Unknown Relevance to Humans; BEI

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): Appendix A - NIOSH Potential Occupational Carcinogens

Health Factors

Carcinogenic Classification:

International Agency for Research on Cancer (IARC) carcinogenic classification: Group 3, not classifiable as to its carcinogenicity to humans

NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 100 ppm

Potential symptoms: Headache; weakness; lethargy; dizziness; drowsiness; confusion, disorientation; unconsciousness; ataxia; eye irritation; respiratory irritation (dryness of throat, coughing, wheezing); dyspnea on effort; tachycardia; cyanosis, jaundice; nausea; sometimes vomiting, ringing in the ears; anorexia, weight loss, anemia; skin lesions; symptoms of bladder cancer (painful urination, blood in the urine, lumps in groin or lower abdomen, pain in lower abdomen or back).

Health Effects: Hematologic (Blood) Disturbances---Methmoglobinemia (HE13) Acute Toxicity--- short-term high hazard effects (HE4); Suspect carcinogen (bladder cancer) (HE2); LD50 (oral, rat) 440 mg/kg.

Affected organs: Blood, cardiovascular system, liver, kidneys, eyes, respiratory system, skin.

Note: Interacts with cytochrome P450 2E1 (both as substrate and inhibitor of other substrates), so there is a potential for interaction with ethanol and acetaminophen.
