Health Haz&ds Information - Recommended Persod Protective Equipment: Organic mask or self-
contained breathiig apparatus; goggles or face shield; rubber gloves; Symptoms Following Exposure:
Inhalation causes irritation of upper respiratory system, nausea, headache, delirium, coma, collapse.
Liquid causes irritation of eyes and skin; prolonged contact with skin may allow penetration into body
and cause same symptoms as following ingestion or inhalation. Ingestion causes nausea, headache,
delirium, coma, collapse; General Treatment for Exposure: INHALATION: remove from Exposure;
give artificial respiration if necessary; call physician. EYES: flush with copious amounts of water; call
physician if contact has been prolonged. IRRITATION: give large amounts of water; get medical
attention; Toxicity by Inhalation (Threshold Limit Value): 5 ppm; Short-Tern Exposure Limits: Data
not available; Toxicity by Ingestion: Grade 3; oral LD,, = 71 mg/kg (rat); Late Toxicity: Damage to
central nervous system and liver Inhalation humans; Vapor (Gas) Irritant Characteristics: Data not

Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Toxic hydrogen chloride and
phosgene fumes may be formed; Behavior in Fire: Vapors are heavier than air and may flash back to
a source of ignition; Ignition Temperature (deg. F): 797; Electrical Hazard: Data not available; Burning
