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. Headache. Laboured breathing. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. Skin burns. Blisters.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Abdominal pain. Diarrhoea. Nausea. Vomiting. Metallic taste.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .

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

Physical dangers
No data. 

Chemical dangers
Mixtures with phosphinic acid, ethanol and acetylene are shock-sensitive. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Decomposes under the influence of light. 

Occupational exposure limits
TLV (as Hg): 0.025mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2008).
MAK: 0.1 mg/m³; Carcinogen category: 3B; Peak limitation category: II(8); Sensitization of skin (SH); BAT issued; (DFG 2008). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. The substance may cause effects on the kidneys. 

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, fatigue, muscle weakness and kidney impairment. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 79°C
Density: 4.4 g/cm³
Solubility in water: good 
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it is persistent. 

NOTES
Depending on the degree of exposure, periodic medical examination is indicated.
Do NOT take working clothes home.
Card has been partially updated in November 2008: see Occupational Exposure Limits, Storage.
