TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Container may explode violently in heat of fire.		In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID EXPOSURE OF (PREGNANT) WOMEN!
INHALATION	Blue lips or finger nails. Blue skin. Cough. Dizziness. Headache. Laboured breathing. Unconsciousness. Symptoms may be delayed (see Notes).	Local exhaust or breathing protection.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
SKIN	(further see Inhalation).	Protective gloves.	First rinse with plenty of water, then remove contaminated clothes and rinse again.
EYES	Redness.	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	(further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS. TURNS DARK ON EXPOSURE TO AIR OR LIGHT.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes (nitrogen oxides). Reacts violently with oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, 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.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood , resulting in formation of methaemoglobin. Exposure to high level may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL
PROPERTIES

Flash point: 190°C
Octanol/water partition coefficient as log Pow: 0.62

ENVIRONMENTAL
DATA

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

NOTES

Temperature of decomposition unknown in literature. Explosive limits are unknown in literature. Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
