Section 03 - Hazard Identification
Inhalation...................鈥︹?︹?︹??.鈥?.... Dust and mist irritate the nose and throat. In confined areas, mechanical
agitation can result in high levels of dust, and reaction with incompatibles
materials (e.g., acids and water/moisture) can result in high concentrations
of chlorine vapour, either of which may result in burns to the respiratory
tract, producing lung edema, shortness of breath, wheezing, choking, chest
pains, impairment of lung function, and possible permanent lung damage.
Skin Contact / Absorption鈥︹??.鈥?.... Calcium hypochlorite dust and solutions can cause irritation and in severe
cases, chemical burns, which are characterized by redness, swelling, and
scab formation. Moisture from perspirations will accelerate tissue
destruction.
Eye Contact................鈥︹?︹?︹??.鈥?.... Exposure to calcium hypochlorite can cause eye irritation and vision
impairment. Contact can produce impairment of vision and corneal
damage.
Ingestion.....................鈥︹?︹?︹?︹?︹??. When ingested, there will be burning of the mouth and throat. Can cause
abdominal cramps, vomiting, diarrhea, nausea, and/or tissue ulceration
which may lead to convulsions, coma, and even death.
Exposure Limits鈥︹?︹?︹?︹?︹?︹?︹??... Ceiling= 3mg/m3 as chlorine (manufacturer's internal standard)
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.
Product #CTAB Page 3 of 8
Ingestion......................鈥︹?︹?︹?︹?︹??. Immediately give large amounts of water. Do not induce vomiting. If
vomiting occurs, lean victim forward to prevent breathing in vomitus. Do
not give anything by mouth to an unconscious or convulsing person. Seek
immediate medical attention.
