TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all exstiguishing agents allowed
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

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

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting.


ICSC: 1696 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.
