TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with combustibles and reducing agents .
Water in large amounts, water spray. NO carbon dioxide.
EXPLOSION Risk of fire and explosion on contact with reducing agents and organic matter.

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION Cough. Sore throat.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Redness. Pain.
Protective gloves.
First rinse with plenty of water, then remove contaminated clothes and rinse again.
•EYES Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal pain. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. (Extra personal protection: P3 filter respirator for toxic particles).
Separated from combustible and reducing substances, acids, and other incompatible materials . See Chemical Dangers. Cool. Dry. Keep in a well-ventilated room.

UN Hazard Class: 5.1
UN Packing Group: II
ICSC: 1045 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:
SLIGHTLY HYGROSCOPIC , WHITE CRYSTALS OR FLAKES

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating to 200°C, producing toxic and corrosive fumes , causing fire and explosion hazard. The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with acids, ammonium compounds, phosphorus, sulfur, sodium dithionate, causing explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below melting point at 180-200°C
Density: 2.5
g/cm3
Solubility in water, g/100 ml at 17°C: 39

ENVIRONMENTAL
DATA


N O T E S

Will turn shock-sensitive if contaminated with organic matter. Rinse contaminated clothes (fire hazard) with plenty of water. Textone is a trade name.
Transport Emergency Card: TEC (R)-209 or 51G02

NFPA Code: H1; F0; R1; OX
