HEALTH HAZARD DATA
Route of Entry and Effects of Short Term (Acute) Exposure –
Inhalation: dust and mist irritate the nose and throat. When mixed with acids, chlorine
gas is released. This gas causes irritation of the respiratory tract. Prolonged exposure to
thigh concentrations of chlorine gas may result in severe lung damage.
Eye Contact: Exposure to calcium hypochlorite can cause eye damage. Concentrated
solutions cause burns which may result in permanent eye damage if not promptly
treated.
Skin Contact: Calcium hypochlorite dust and solutions can cause irritation, and in
severe cases, chemical burns.
Ingestion: When ingested, there will be burning in the mouth and throat. Calcium
hypochlorite can cause abdominal cramps and nausea, which may lead to convulsions,
coma and death.
Route of Entry and Effects of Short Term (Acute) Exposure –
Skin irritation may occur from repeated or prolonged skin contact.
