irritates eyes; General Treatment for Exposure: INHALATION: remove victim from contaminated area
and call physician if unconscious; if breathing is irregular or stopped, give oxygen and start
resuscitation. EYES OR SKIN: flush with plenty of water for 15 min.; Toxicity by Inhalation
(Threshold Limit Value): 75-100 ppm; Short-Term Exposure Limits: Data not available; Toxicity by
Ingestion: Grade 2; oral rat LDm 0.82 g/kg; Late Toxicity: Data not available; Vapor (Gas) Im’tant

approved respirator; clean rubber gloves; goggles or face shield; Symptoms Following Exposure:
Inhalation, ingestion, or skin contact causes irritability, convulsions and/or coma, nausea, vomiting,
headache, fainting, tremors. Contact with eyes causes irritation; General Trement for Exposure:
INHALATION: move to fresh air; give oxygen and artificial respiration as required. INGESTION:
induce vomiting and get medical attention. EYES: flush with plenty of water; Toxicity by Inhalation
(73reshold Limit Value): 0.25 mg/m3; Short-Term Exposure Limits: 1 mg/m3 for 30 min.; Toxicity by
Ingestion: Grade 4; oral LDm 46 mg/kg (rat), 65 rng/kg (dog); Late Toxicity: Banned by EPA in
