Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).
Use water spray, powder, alcohol-resistant foam, carbon dioxide.
Avoid inhalation of dust.
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered suitable containers. Do NOT let this chemical enter the environment.
According to UN GHS Criteria
Transportation UN Classification
Separated from strong oxidants and strong acids.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-WHITE SOLID IN VARIOUS FORMS.
Physical dangers Dust explosion possible if in powder or granular form, mixed with air. As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical dangers Decomposes on heating and on burning. This produces toxic fumes. Reacts with oxidants and strong acids.
Molecular mass: variable (polymer)
Decomposes at >200°C Density: 1.19-1.31 g/cm³ Solubility in water: good Flash point: 79°C o.c.
