  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion.      In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Shortness of breath. Fever. Vomiting. Diarrhoea. Abdominal pain. Headache. Weakness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin MAY BE ABSORBED! Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. See Notes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   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   Do not eat, drink, or smoke during work. Wash hands before eating.  Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
ODOURLESS HEAVY MOBILE SILVERY LIQUID METAL. 

Physical dangers
 

Chemical dangers
Upon heating, toxic fumes are formed. Reacts violently with ammonia, halogens, acetylene and amines. This generates fire and explosion hazard. Attacks aluminium and many other metals. This produces amalgams. 

Formula: Hg
Atomic mass: 200.6
Boiling point: 357°C
Melting point: -39°C
Density: 13.5 g/cm³
Solubility in water: none
Vapour pressure, Pa at 20°C: 0.26
Relative vapour density (air = 1): 6.93
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.009 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and through the skin also as a vapour. 

Effects of short-term exposure
The substance is irritating to the skin. Inhalation of high concentrations of the vapour may cause pneumonitis. This may result in death. The substance may cause effects on the central nervous system and kidneys. This may result in tremors and tissue lesions. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system and kidneys. This may result in irritability, emotional instability, tremors, mental and memory disturbances and speech disorders. May cause inflammation and discoloration of gums. Cumulative effects are possible. Animal tests show that this substance possibly causes toxic effects upon human reproduction. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.025 mg/m3, as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued.
EU-OEL: 0,02 mg/m3 as TWA.
MAK: (inhalable fraction): 0.02 mg/m3; peak limitation category: II(8); skin absorption (H); sensitization of skin (SH); carcinogen category: 3B; pregnancy risk group: D 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish and seafood. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
There is no odour warning even when toxic concentrations are present.
Do NOT take working clothes home.
Isolate contaminated clothing by sealing in a bag or other container.
Other UN number: 3506 Mercury contained in manufactured articles.
