Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Table Z-1 -- 0.25 mg/m3 TWA; Skin

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 0.25 mg/m3 TWA; Skin

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.25 mg/m3 TWA; Skin; Appendix A3 (Confirmed Animal Carcinogen with Unknown Relevance to Humans)

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.25 mg/m3 TWA; Skin; Appendix A - Potential Occupational Carcinogen

Health Factors

Carcinogenic Classification:

International Agency for Research on Cancer (IARC): Group 3, not classifiable as to its carcinogenicity to humans [1 MB PDF, 454 pages]

NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 25 mg/m3

Potential Symptoms: Headache, dizziness; nausea, vomiting, malaise; mild erythema of skin; impairment of memory, emotional disturbances; tremors, hyperexcitability, myoclonic jerks of limbs; clonic-tonic convulsions, coma, respiratory failure (carcinogenic)

Health Effects: CNS Disturbances (HE7); LD50 (oral, rat) 39-45 mg/kg; (dermal, rat) 98 mg/kg

Affected Organs: CNS, liver, kidneys

Note: Metabolized in the body to dieldrin, also a previously used insecticide. Neither has been produced or used since 1989, but may remain in buildings treated for termites or in chemical dumping sites.
