TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Liquid formulations containing organic solvents may be flammable.		Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION

EXPOSURE		AVOID EXPOSURE OF (PREGNANT) WOMEN!
Inhalation		Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes		Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALLINE POWDER, WITH CHARACTERISTIC ODOUR.

Chemical dangers
The substance decomposes on heating producing toxic fumes including nitrogen oxides.

Occupational exposure limits
TLV: 10 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: sensitization of skin (Sh); Germ cell mutagen group: 3A (DFG 2005).

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
The substance irritates the skin.

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. Animal tests show that this substance possibly causes malformations in human babies.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Decomposes below melting point Solubility in water: none	The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
