TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ 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 contact with flammable substances. NO contact with combustibles, reducing agents, and organic materials.	Water in large amounts.
EXPLOSION	Risk of fire and explosion.		In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST!
•INHALATION	Cough. Sore throat. Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN	Redness.	Protective gloves.	First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
•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	Abdominal pain. Diarrhoea. Shortness of breath. Vomiting. (Further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. 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. Personal protection: P2 filter respirator for harmful particles.

Separated from combustible and reducing substances, and incompatible materials . See Chemical Dangers.

PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS CRYSTALS OR WHITE GRANULES.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating above 300°C producing oxygen , which increases fire hazard, and toxic fumes ( chlorine ). The substance is a strong oxidant and reacts violently with combustible and reducing materials, causing fire and explosion hazard. Reacts with many organic materials to form shock-sensitive mixtures, causing explosion hazard. Attacks zinc and steel.

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 on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract The substance may cause effects on the blood , resulting in formation of methaemoglobin, and on kidneys , resulting in kidney impairment. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point at ca. 300°C
Melting point: 248°C
Density: 2.5
g/cm3

Solubility in water, g/100 ml at 20°C: 100

ENVIRONMENTAL
DATA

N O T E S

The substance is entirely decomposed at temperature higher than 300°C. Will turn shock-sensitive if contaminated with organic materials. Marketed formulations contain a flame retardant. Depending on the degree of exposure, periodic medical examination is suggested. Rinse contaminated clothes (fire hazard) with plenty of water. Dervan, Defol, Chlorax and Atlacide are trade names. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
