TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances.	NO contact with combustible substances and incompatible substances such as acetylene, alkalies, halides and other compounds.	Water in large amounts. In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
INHALATION	Burning sensation. Cough. Laboured breathing.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	Redness. Skin burns. Pain.	Protective gloves. Protective clothing.	First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
EYES	Redness. Pain. Loss of vision. Severe deep burns.	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 take to a doctor.
INGESTION	Abdominal pain. Burning sensation. Weakness.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS TRANSPARENT OR WHITE CRYSTALS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
Shock-sensitive compounds are formed with. The substance decomposes on heating producing toxic fumes (nitrogen oxides). The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts with incompatible substances such as acetylene, alkalies, halides and other compounds causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings. The substance decomposes on contact with organic contaminants when exposed to light.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as Ag): ppm; 0.01 mg/m³ (ACGIH 1991-1992).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in forming of methaemoglobin. Inhalation or ingestion can lead to generalized argyria, a grey pigmentation of the skin and brown fingernails.

PHYSICAL
PROPERTIES

Decomposes below boiling point at 444°C

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to fish.

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. Rinse contaminated clothes (fire hazard) with plenty of water.
