Section 03 - Hazard Identification
Inhalation...................鈥︹?︹?︹??.鈥?.... Low concentrations may cause sore throat, coughing, choking, dyspnea,
and variable symptoms of headache, dizziness, and weakness. Intense
exposures may result in tightness in the chest and delayed pulmonary
edema. The solubility of substance allows penetration that may continue
for several days.
Skin Contact / Absorption鈥︹??.鈥?.... Can penetrate the skin slowly, producing soft, necrotic, deeply penetrating
areas on contact. The extent of damage depends on the duration of
contact. Removes natural skin oils.
Eye Contact................鈥︹?︹?︹??.鈥?.... Severe eye irritation, intense watering of the eyes, possible lesions,
possible blindness when exposed for prolonged period.
Ingestion.....................鈥︹?︹?︹?︹?︹??. Causes gastrointestinal tract burns. May cause circulatory system failure.
May cause perforation of the digestive tract. Causes severe pain, nausea,
vomiting, diarrhea, and shock. Effects may be delayed.
Exposure Limits鈥︹?︹?︹?︹?︹?︹?︹??... ACGIH/TLV-TWA = 5mg/m3
NIOSH/TLV-TWA = 5mg/m3
OSHA/PEL-TWA= 15 mg/m3(total dust); 5mg/m3(respirable fraction)
Section 04 - First Aid Measures
Inhalation....................鈥︹?︹?︹?︹?︹??.. Remove victim to fresh air. Give artificial respiration only if breathing has
stopped. If breathing is difficult, give oxygen. Seek immediate medical
attention.
Skin Contact / Absorption鈥︹?︹?︹??.. Remove contaminated clothing. Wash affected area with soap and
water. Seek medical attention if irritation occurs or persists.
Eye Contact..................鈥︹?︹?︹?︹??.... Flush immediately with water for at least 20 minutes. Forcibly hold
eyelids apart to ensure complete irrigation of eye tissue. Seek immediate
medical attention
Ingestion......................鈥︹?︹?︹?︹?︹??. If victim is conscious, give 300mL of water, followed by diluted vinegar (1
part vinegar, 2 parts water) or fruit juice to neutralize the alkali. Do not
induce vomiting. Contact a physician immediately.
