Health Hazards Information - Recommended Personal Protective Equipment: Chemical goggles and
full face shield; molded rubber acid gloves; self-contained breathing apparatus; Symptoms Following
Exposure: Inhalation at high concentration (> 100 ppm) causes nose and throat irritation progressing
all the way to pulmonary edema. Eye and skin irritation; General Treatment for Exposure:
INHALATION: remove victim to fresh air and calla physician; if breathing has stopped, administer
artificial respiration and oxygen; keep victim warm and quiet; do not give stimulants. EYES: flush
continuously and thoroughly with water for at least 15 min. SKIN: remove contaminated clothing
immediately; flush affected area with large amounts of water and then wash with soap and water;
Toxicity by Inhalation (Threshold Limit Value): 10 ppm; Short-Tern Exposure Limits: 20 ppm for 5
min.; Toxicity by Ingestion: Not pertinent; Lute Toxicity: None; Vapor (Gus) Initant Characteristics:
Vapors cause moderate irritation such that personnel will fid high concentrations unpleasant. The
effect is temporary; Liquid or Solid Irritant Characteristics: Causes smarting of the skin and fist-
degree burns on short exposure and may cause secondary burns on long exposure; Odor Threshold
0.047.
