Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances or reducing agents.
NO contact with combustible substances or reducing agents.
Use water in large amounts. In case of fire: keep drums, etc., cool by spraying with water.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
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.
Abdominal pain. Diarrhoea. Nausea. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
CLASSIFICATION & LABELLING
Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: P3 filter respirator for toxic particles.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 5.1; UN Pack Group: II
Separated from combustible substances, reducing agents, powdered metals and incompatible materials. See Chemical Dangers.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE CRYSTALS OR POWDER.
Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with aluminium, disulfur dibromide, arsenic, carbon, copper, metal sulfides, phosphorus and sulfur. This generates fire hazard.
Molecular mass: 167.0
Decomposes at 370°C Melting point: 350°C Density: 3.27 g/cm³ Solubility in water, g/100ml at 25°C: 7.5
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. Ingestion could cause effects on the kidneys and central nervous system. This may result in renal failure, respiratory depression and hearing loss. The effects may be delayed.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of long-term or repeated exposure This substance is possibly carcinogenic to humans.
OCCUPATIONAL EXPOSURE LIMITS
Will turn shock-sensitive if contaminated with organic substances. Rinse contaminated clothing with plenty of water because of fire hazard.
