TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!
Inhalation		Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain. Severe deep burns.	Safety goggles, 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. Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention. Rest.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Then remove to safe place. (Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust.)	Xn Symbol R: 22-38-41-48/22 S: (2-)26-36/37/39-46

EMERGENCY RESPONSE	STORAGE
NFPA Code: H1; F1; R0	Separated from strong oxidants, and acids. Dry.

IMPORTANT DATA

Physical State; Appearance
WHITE CRYSTALS OR COLOURLESS VISCOUS HYGROSCOPIC LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
The vapour is heavier than air.

Chemical dangers
The substance decomposes on burning producing toxic fumes. The solution in water is a medium strong base. Reacts violently with strong oxidants, strong acids. Attacks copper, zinc, aluminium, and their alloys.

Occupational exposure limits
TLV: 2 mg/m³; (skin); (ACGIH 2002).
MAK: class Carcinogen category: 3A; Sh, H (2002).

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

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.

Effects of short-term exposure
The substance is corrosive to the eyes.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver and kidneys.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 269°C Melting point: 28°C Relative density (water = 1): 1.09 (liquid) Solubility in water: very good Vapour pressure, Pa at 20°C: <1 Relative vapour density (air = 1): 3.65 Flash point: 134°C o.c. Auto-ignition temperature: 662°C Explosive limits, vol% in air: 1.7-9.8 Octanol/water partition coefficient as log Pow: -1.43	The substance is harmful to aquatic organisms.
