  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but forms flammable gas on contact with water or damp air. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames, NO sparks and NO smoking. NO contact with water, carbon dioxide or acids. NO contact with hot surfaces.    Use powder, dry sand. NO hydrous agents. NO water. NO carbon dioxide.   

 STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Chest tightness. Confusion. Convulsions. Cough. Dizziness. Headache. Laboured breathing. Nausea. Shortness of breath. Unconsciousness. Vomiting. Weakness. Red skin.  Use local exhaust or breathing protection.  Fresh air, rest. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes. 
Skin MAY BE ABSORBED! Redness. Pain. Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . Wear protective gloves when administering first aid. See Notes. 
Eyes Redness. Pain.  Wear safety spectacles, face shield 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 Burning sensation in the throat and chest. Further see Inhalation.  Do not eat, drink, or smoke during work. Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . See Notes.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes above 350°C . This produces toxic fumes including nitrogen oxides and hydrogen cyanide. Reacts violently with water, moist air, carbon dioxide, acids and acid salts. This produces highly toxic and flammable hydrogen cyanide. Reacts violently with oxidizing substances when heated. This generates fire and explosion hazard. 

Formula: C2CaN2 / Ca(CN)2
Molecular mass: 92.1
Decomposes at >350°C
Density: 1.8 g/cm³
Solubility in water: reaction 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the intracellular oxygen metabolism. This may result in seizures and unconsciousness. Exposure could cause death. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact with skin may cause dermatitis. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (ceiling value): 5 mg/m3 as STEL; (skin).
MAK: (as CN): 2 mg/m3; peak limitation category: II(1); skin absorption (H); pregnancy risk group: C 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
There is no odour warning even when toxic concentrations are present.
Do NOT take working clothes home.
