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.	Foam, powder, carbon dioxide, water in large amounts.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
Inhalation	Abdominal cramps. Confusion. Cough. Dizziness. Headache.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Dry skin. Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	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	Abdominal pain. Diarrhoea. Nausea. Vomiting. (Further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Let solidify if molten. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Personal protection: P2 filter respirator for harmful particles.	Xn Symbol R: 20/22-36/37/38 S: ()2

EMERGENCY RESPONSE	SAFE STORAGE
NFPA Code: H 1; F 1; R 0	Separated from strong oxidants. Dry.

IMPORTANT DATA

Physical State; Appearance
WHITE, HYGROSCOPIC FLAKES OR CRYSTALS.

Chemical dangers
The substance decomposes on heating and on burning producing toxic fumes including nitrogen oxides, ammonia. Reacts violently with strong oxidants producing toxic fumes.

Occupational exposure limits
TLV: 5 mg/m³ as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2004).
MAK: (Inhalable fraction) 5 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour or dust.

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
The substance is irritating to the skin. The vapour is irritating to the eyes and the respiratory tract. Inhalation of the vapour may cause effects on the central nervous system.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the nervous system liver.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 267°C Melting point: 70°C Relative density (water = 1): 1.02 Solubility in water: good Vapour pressure, Pa at 25°C: 0.26 Relative vapour density (air = 1): 3.91 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 125°C o.c. Auto-ignition temperature: 375°C Explosive limits, vol% in air: 1.4-8 Octanol/water partition coefficient as log Pow: -0.19	This substance may be hazardous to the environment; special attention should be given to aquatic organisms.

NOTES

The substance is usually used, stored and transported in liquefied form at about 80°C.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
