EXPLOSION

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Abdominal pain. Nausea. Vomiting. Fever and chill.	Ventilation (not if powder), local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes		Safety spectacles, or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Jaundice. (Further see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers;if appropreate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS TO PALE YELLOW FLAKES, WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO AIR.

Chemical dangers
The substance decomposes on heating or on burning producing toxic fumes including aniline and nitrogen oxides. The substance is a weak base. Reacts violently with strong oxidants.

Occupational exposure limits
TLV: 0.1 ppm as TWA (skin) A3 (ACGIH 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, 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.

Effects of short-term exposure
The substance may cause effects on the liver, resulting in liver impairment.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point at 102 kPa: 398-399°C Melting point: 91.5-92°C Density: 0.5 g/cm³ Solubility in water: poor Vapour pressure, Pa at 197°C: 133 Flash point: 220°C c.c. Octanol/water partition coefficient as log Pow: 1.6	The substance is harmful to aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Ancamine TL, Araldite hardener 972, Epicure DDM, Slumicure M, Tonox are trade names.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
