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, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Dullness. Headache.	Closed system and ventilation.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
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		Do not eat, drink, or smoke during work.	Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).	EU classification T Symbol R: 45-22 S Note: E: 53-45	Unbreakable packaging; put breakable packaging into closed unbreakable container.

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61G12b NFPA Code: H2; F1; R0	Separated from strong oxidants. Well closed.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS SOLID IN VARIOUS FORMS, WITH CHARACTERISTIC ODOUR. TURNS PURPLE ON EXPOSURE TO AIR.

Chemical dangers
On combustion, forms toxic gases. The solution in water is a weak base. Reacts with strong oxidants.

Occupational exposure limits
TLV: A1 (skin) (ACGIH 1996).
MAK: skin absorption (H); Carcinogen category: 1 (DFG 2006).

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly by dispersing.

Effects of short-term exposure
The substance irritates the eyes. The substance may cause effects on the bladder, resulting in blood in urine.

Effects of long-term or repeated exposure
This substance is carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 302°C Melting point: 53°C Relative density (water = 1): 1.2 Solubility in water, g/100 ml at 25°C: 0.2 Flash point: 153°C c.c. Auto-ignition temperature: 450°C Octanol/water partition coefficient as log Pow: 2.8

NOTES

Periodic medical examination is indicated. Special attention should be given to urine sediment and cytology.
Do NOT take working clothes home.
Card has been partially updated in August 2007: see Occupational Exposure Limits.
