CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Personal protection: protective gloves. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Chemical dangers Decomposes on heating and on burning. This produces toxic and corrosive gases including nitrogen oxides and sulfur oxides.
Molecular mass: 1128
Decomposes at ~330°C Melting point: >300°C Solubility in water, g/100ml at 20°C: 15 (good) Octanol/water partition coefficient as log Pow: -2.8
EXPOSURE & HEALTH EFFECTS
Routes of exposure
Effects of short-term exposure The substance is mildly irritating to the eyes.
Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
Effects of long-term or repeated exposure
