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 open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with combustible and reducing materials, and organic materials.	Water in large amounts.
EXPLOSION	Risk of fire and explosion on contact with flames, sparks and organic materials (such as clothing, leather and paper) or other incompatible materials.		In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
INHALATION	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	Redness.	Protective gloves. Protective clothing.	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. Blue lips or fingernails. Blue skin. Diarrhoea. Nausea. Shortness of breath. Unconsciousness. Vomiting.	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. 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).

Separated from combustible, flammable, organic or other readily oxidizable materials. Dry. Keep in a well-ventilated room. Avoid storage on wooden floors.

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

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating above 300°C or on burning 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 strong acids giving off carbon dioxide. Reacts with organic contaminants to form shock-sensitive mixtures. Attacks zinc and steel.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
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 irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the blood (methaemoglobinaemia) and kidneys following ingestion. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.

PHYSICAL
PROPERTIES

Decomposes below boiling point at ca. 300°C
Melting point: 248°C
Relative density (water = 1): 2.5
Solubility in water, g/100 ml at 20°C: 100

Vapour pressure, Pa at °C: negligible
Relative vapour density (air = 1): 3.7
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00

ENVIRONMENTAL
DATA

NOTES

The substance is entirely decomposed at temperature higher than 300°C. Will turn shock-sensitive if contaminated with organic materials. Marketed formulations contain a fire depressant. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Rinse contaminated clothes (fire hazard) with plenty of water.

NFPA Code: H 1; F 0; R 2;
