Health Hazards Information - Recommended Personal Protective Equipment: Protective gloves;
goggles or face shield; approved respirator (for major spills); Symptoms Following Erposure: Inhalation
of high concentrations of vapor may result in narcosis; peripheral neuropathy may develop. Ingestion
of large amounts may cause some systemic injury. Contact with eyes causes mild to moderate irritation.
Liquid irritates skin; prolonged or repeated contact may cause defatting of the skin with resultant
dermatitis; General Treatment for Exposure: INHALATION: move to uncontaminated atmosphere and
treat symptomatically; alert physician to possible development of peripheral neuropathy. INGESTION:
give large amount of water and induce vomiting. EYES: irrigate immediately and thoroughly with
water for 15 min. and get medical attention. SKIN: flush exposed areas thoroughly with water; Toxicity
by Inhalation (Threshold Limit Value): 100 ppm; Short-Term Inhalation Limits: Data not available;
Toxicity by Ingestion: Grade 2; oral LD,, = 2,590 mg/kg (rat); Late Toxicity: Peripheral neuropathy
in experimental animals and man (disease of motor and/or sensor nerves); Vapor (Gas) Irritant
