Physical dangers
 

Chemical dangers
Decomposes on heating and under the influence of light. This produces toxic fumes of mercury and chlorine. Reacts with metals such as aluminium, copper, iron and zinc. 

Occupational exposure limits
TLV (as Hg): 0.025mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2014).
EU OEL (as Hg): 0.02 mg/m³ as TWA. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance is corrosive to the eyes and skin. The substance is irritating to the respiratory tract. The substance may cause effects on the gastrointestinal tract and kidneys. This may result in tissue lesions, kidney failure, collapse and death. Medical observation is indicated. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the central nervous system, peripheral nervous system and kidneys. This may result in ataxia, sensory and memory disturbances, tremors, muscle weakness and kidney impairment. The substance may have effects on male fertility. May cause heritable genetic damage to human germ cells.
