TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, dry powder, foam, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES Redness.
Safety spectacles
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Separated from bases, strong oxidants and food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Do not transport with food and feedstuffs.
UN Hazard Class: 6.1
UN Packing Group: II
Signal: Warning
Excl mark
Harmful if swallowed
Toxic to aquatic life
ICSC: 1618 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.
