Hazardous Substances:  Antimony and Compounds

Antimony and its compounds can create ill-health through inhalation, and contact with nose, throat, eyes and skin.

Effects

Antimony and its compounds can cause irritation of the eyes, nose, mouth, skin and throat. Loss of appetite, nausea and vomiting
may be present. In severe cases blood may be vomited or passed per rectum. The irritant effects on the lungs will initially cause
coughing and as the poisoning becomes more severe, pneumonitis and shortness of breath will develop. Central nervous system
effects include headache, respiratory depression, eventual coma and finally death.

Full recovery is expected from the early stages of poisoning. If the patient develops a severe pneumonitis it is possible that a
permanent respiratory disability may result. If poisoning progresses to coma it is always possible that some residual central nervous
system effects will be permanent.

Prevention

Enclose process
Local exhaust ventilation
General exhaust ventilation
Personal protective equipment
