TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances.	NO contact with water, combustible substances or reducing agents.	NO water. Use dry powder.
EXPLOSION	Risk of fire and explosion on contact with combustible substances.		In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Serious skin burns. Pain.	Protective gloves. Protective clothing.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
Eyes	Redness. Pain. Blurred vision. Severe deep burns.	Wear face shield or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Sore throat. Abdominal pain. Nausea. Shock or collapse. Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Then store and dispose of according to local regulations.

IMPORTANT DATA

Physical State; Appearance
YELLOW-TO-WHITE POWDER.

Physical dangers

Chemical dangers
Reacts with water. This generates fire hazard. Reacts with organic compounds and powdered metals. This generates explosion hazard. The substance is a strong oxidant. It reacts violently with combustible and reducing materials.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
The substance is very corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema. See Notes.

Effects of long-term or repeated exposure

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Decomposes at 460°C Density: 2.8 g/cm³ Solubility in water: reaction	The substance is harmful to aquatic organisms.

NOTES

Rinse contaminated clothes (fire hazard) with plenty of water.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
