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			In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Sore throat. Headache. Confusion. Weakness. Shortness of breath. Convulsions. Unconsciousness. See Notes.	Local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness. Pain. (See Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes	Redness. Pain.	Safety goggles, 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 take to a doctor.
Ingestion	Burning sensation. Nausea. Vomiting. Diarrhoea. (See Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Wear protective gloves when inducing vomiting. Give a slurry of activated charcoal in water to drink. No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Refer for medical attention. See Notes.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Sweep spilled substance into sealable containers.

IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS, WITH PUNGENT ODOUR.

Chemical dangers
The substance decomposes on contact with acids, bases, ammonia alcohols, and on heating producing toxic gases including hydrogen cyanide. Reacts with carbon dioxide or slowly with water to produce hydrogen cyanide.

Occupational exposure limits
TLV not established. Decomposition in moist air results in hydrogen cyanide exposure: TLV: (for Hydrogen cyanide and some cyanide salts, as CN) 4.7 ppm as STEL; (Ceiling value); (ACGIH 2005).
MAK: (as CN) (Inhalable fraction) 2 mg/m³; Peak limitation category: II (1); skin absorption (H); Pregnancy risk group: C; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin 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 severely irritating to the eyes the skin and the respiratory tract. The substance may cause effects on the cellular respiration, resulting in convulsions and unconsciousness. Exposure may result in death. Medical observation is indicated. See Notes.

Effects of long-term or repeated exposure
The substance may have effects on the thyroid.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 146-147°C Density: 2.84 g/cm³ Solubility in water: slow reaction Vapour pressure, Pa at 25.2°C: 130 Relative vapour density (air = 1): 1.54	The substance is very toxic to aquatic organisms.

NOTES

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Do NOT take working clothes home.
