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.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:


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.
