TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
Inhalation
Ventilation (not if powder).
Refer for medical attention.
Skin
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap.
Eyes Redness.
Safety spectacles.
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.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.
Do not transport with food and feedstuffs.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including hydrogen chloride, nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: (Inhalable fraction) 2 mg/m; Peak limitation category: II(8); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation 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 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating 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. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Decomposes below boiling point: see Notes
Melting point: 173-177C
Relative density (water = 1): 1.2
Solubility in water, g/100 ml at 25C: (none)
Vapour pressure, Pa at 20C: negligible
Octanol/water partition coefficient as log Pow: 2.34
ENVIRONMENTAL DATA
This substance may be hazardous in the environment; special attention should be given to plants, soil organisms and aquatic organisms.
