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. Foam. Carbon dioxide. Powder
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION Cough.
Avoid inhalation of dust
Fresh air, rest.
•SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Safety goggles.
Rinse with plenty of water (remove contact lenses if easily possible).
•INGESTION Abdominal pain. Diarrhoea.
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 non-metal containers. Carefully collect remainder, then remove to safe place.
Separated from strong oxidants, metals , food and feedstuffs.

Signal: Warning
May be harmful if swallowed
Causes eye irritation
ICSC: 0886 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.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR WHITE POWDER.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of nitrous oxides. Reacts with strong oxidants. Attacks some forms of metal s and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of the dust or aerosol and by ingestion.

INHALATION RISK:
A nuisance-causing concentration of airborne particles can be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
