Health Hazards Information - Recommended Personal Protective Equipment: An approved full face
mask equipped with a fresh black canister meeting specifications of the U.S. Bureau of Mines for
organic vapors, a full face self-contained breathing apparatus, or full face air-supplied respirator;
Symptoms Following Exposure: Smarting of skin and eyes. Prolonged contact of liquid with skin may
cause second-degree burns; General Treatment for Exposure: INHALATION: remove patient to fresh
air, keep warm and quiet; call physician immediately; give artificial respiration if breathing has
stopped. INGESTION: call physician immediately. Induce vomiting by giving an emetic, e.g., 2
tablespoons table salt in glass of warm water. SKIN OR EYES: immediately remove contaminated
clothing and shoes. Wash skin with soap and plenty of water. For eyes, flush immediately with plenty
of water for at least 15 min. Call physician; Toxicity by Inhalation (ThresholdLimit Vdue): Data not
available; Short-Tern Exposure Limits: Data not available; Toxicity by Ingestion: Grade 3; LDs0 50 to
500 mg/kg; Late Toxicity: Data not available; Vqor (Gas) Irritant Characteristics: Vapors cause
moderate irritation such that personnel will find high concentrations unpleasant. The effect is
temporary; Liquid or Solid Irritant characteristics: Causes smarting of the skin and first degree burns
on short exposure and may cause secondary burns on long exposure; Odor Threshold Data not
available.
