CALCIUM CYANIDE

ICSC: 0407

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALS OR WHITE POWDER WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers Decomposes above 350°C . This produces highly toxic fumes including nitrogen oxides and hydrogen cyanide (see ICSC 0492). Reacts with water, moist air, carbon dioxide, acids and acid salts. This produces highly toxic and flammable hydrogen cyanide (see ICSC 0492).	Formula: C₂CaN₂ / Ca(CN)₂ Molecular mass: 92.1 Decomposes at >350°C Density (at 20 °C): 1.9 g/cm³ Solubility in water: freely soluble

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 cellular respiration. This may result in convulsions and unconsciousness. Exposure could cause death. Medical observation is indicated. See Notes.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure The substance may have effects on the thyroid. This may result in impaired functions.

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 cellular respiration. This may result in convulsions and unconsciousness. Exposure could cause death. Medical observation is indicated. See Notes.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure
The substance may have effects on the thyroid. This may result in impaired functions.

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. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment.

NOTES
Do NOT take working clothes home. Isolate contaminated clothing by sealing in a bag or other container. 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.
