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 combustible substances.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances or reducing agents.    In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Sore throat. Wheezing. Laboured breathing.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Burning sensation. Pain.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes Redness. Pain.  Wear safety goggles 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 Nausea. Diarrhoea. Vomiting. Sore throat.  Do not eat, drink, or smoke during work. Wash hands before eating.  Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Carefully collect remainder. Then wash away with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.

COLOURLESS CRYSTALS OR WHITE POWDER. 

Physical dangers
 

Chemical dangers
The substance is a strong oxidant. It reacts with combustible and reducing materials. Decomposes on heating. This produces toxic and corrosive fumes including ammonia, nitrogen oxides and sulfur oxides. If in solution, reacts violently with iron, powdered aluminium and silver salts. The solution in water is a medium strong acid. 

Occupational exposure limits
MAK: Sensitization of respiratory tract and skin (SAH); (DFG 2006). 

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, skin and respiratory tract. Inhalation of dust may cause asthma-like reactions. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause asthma. Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. May cause a general allergic reaction, such as urticaria or shock. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 120°C
Density: 1.9 g/cm³
Solubility in water, g/100ml at 20°C: 58.2   		The substance is harmful to aquatic organisms. 

NOTES
Rinse contaminated clothes (fire hazard) with plenty of water.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Do NOT take working clothes home.
Card has been partially updated in August 2007: see Ingestion First Aid, Occupational Exposure Limits, Physical Properties.
