American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 1.5 mg/m3 TWA
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 1.5 mg/m3 TWA; Skin
Health Factors
NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 750 mg/m3
Potential symptoms: Sensitization dermatitis, itching, erythema; edema on nasal folds, cheeks, neck; keratitis (inflammation of the cornea), conjunctivitis; nosebleeds; sneezing; anemia; cough, coryza, wheezing; irritability, malaise, headache, lassitude, insomnia; nausea, vomiting, abdominal pain; yellow stains of skin and hair; hair loss; liver, kidney damage.
Health Effects: Irritation-Eyes, Nose, Throat, Skin---Mild to Marked (HE14-16); Asthma-like symptoms (HE9); Allergic contact dermatitis/Cumulative systemic toxicity (HE3); Mutagen (HE2); CNS effects (HE7); Explosive (HE18).
Affected organs: Eyes, skin, respiratory system, CNS, liver, kidneys, GI tract
Notes:
- The extent of tetryl absorption through the skin, the metabolism of tetryl in humans, the mechanism of tetryl toxicity, and specific biomarkers for medical surveillance have not been elucidated.
- Because the CNS effects are minor and nonspecific, it is possible that most of them may occur secondarily to intense itching from dermatitis, intestinal discomfort, or respiratory symptoms that interfere with sleep.
- The anemia is generally mild and there is no conclusive evidence to associate it with exposure to tetryl.
