TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention . 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Metallic taste. Burning sensation. Nausea. Abdominal pain. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE HYGROSCOPIC POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. The substance is a strong oxidant. It reacts violently with combustible and reducing materials and powdered metals. Mixtures with reducing agents or reduced materials such as organic substances can be explosive. 

Occupational exposure limits
TLV (as Hg): 0.025mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2013).
EU OEL (as Hg): 0.02 mg/m³ as TWA. 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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 severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the gastrointestinal tract and kidneys. This may result in tissue lesions and kidney failure. 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, kidneys and peripheral nervous system. 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. See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 79°C
Density: 4.4 g/cm³
