TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE


•INHALATION Cough.
Avoid inhalation of dust .
Fresh air, rest.
•SKIN

Rinse and then wash skin with water and soap.
•EYES Redness.
Safety spectacles .
First rinse with plenty of water (remove contact lenses if easily possible).
•INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting.
Separated from strong oxidants, strong bases, strong acids .

ICSC: 1701 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.
