TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking. NO contact with flammable substances.	In case of fire in the surroundings: water in large amounts, water spray.
EXPLOSION		Do NOT expose to friction or shock.	In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. (Extra personal protection: P2 filter respirator for harmful particles).	O Symbol Xn Symbol R: 9-22 S: (2-)13-22-27 UN Hazard Class: 5.1 UN Pack Group: II

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-51S1489 NFPA Code: H 1; F 0; R 2; ox	Separated from combustible and reducing substances. See Chemical Dangers.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE CRYSTALLINE POWDER

Chemical dangers
The substance decomposes on heating producing toxic and corrosive fumes (chlorine, chloroxides). The substance is a strong oxidant and reacts with combustible and reducing materials, causing fire and 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.

Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
The substance may have effects on the blood, resulting in formation of methaemoglobin. (See Notes).

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point (decomposes): 400°C Density: 2.5 g/cm³ Solubility in water, g/100 ml at 20°C: 1.8

NOTES

Will turn shock-sensitive if contaminated with organic substances.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Rinse contaminated clothes (fire hazard) with plenty of water.
Depending on the degree of exposure, periodic medical examination is indicated.
