TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed. See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin     Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal cramps. Diarrhoea. Nausea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
ODOURLESS BROWN CRYSTALS OR AMORPHOUS POWDER. 

Physical dangers
 

Chemical dangers
Reacts violently with magnesium when heated. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (as Cd total dust): 0.01mg/m³ as TWA; A2 (suspected human carcinogen); BEI issued; (ACGIH 2005).
TLV (respirable fraction): 0.002mg/m³ as TWA; A2 (suspected human carcinogen); BEI issued; (ACGIH 2005).
MAK (inhalable fraction): Carcinogen category: 1; Germ cell mutagen group: 3A; Skin absorption (H); (DFG 2005). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol 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 irritating to the respiratory tract. May cause mechanical irritation to the to the eyes. Inhalation of of the aerosol may cause lung oedema. See Notes. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the kidneys and lungs. This may result in kidney impairment and tissue lesions. This substance is carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: 1559°C (crystals)
Decomposes at 900-1000°C (amorphous)
Density (amorphous): 6.9 g/cm³
Density (crystals): 8.15 g/cm³
Solubility in water: none 
Bioaccumulation of this chemical may occur in plants and seafood. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
