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 reducing agents or organic materials.
NO contact with combustible substances or reducing agents.
Use water in large amounts, water spray. NO carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
PREVENT DISPERSION OF DUST!
Cough. Sore throat.
Use ventilation (not if powder), local exhaust or breathing protection.
Fresh air, rest.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.
Wear safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Abdominal pain. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered 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.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 5.1; UN Pack Group: II
Separated from combustible substances, reducing agents, acids and incompatible materials. See Chemical Dangers. Cool. Dry. Keep in a well-ventilated room.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance SLIGHTLY HYGROSCOPIC WHITE CRYSTALS OR FLAKES.
Chemical dangers Decomposes at 200°C. This produces toxic and corrosive fumes. This generates fire and explosion hazard. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with acids, ammonium compounds, phosphorus, sulfur and sodium dithionate. This generates explosion hazard.
Molecular mass: 90.44
Decomposes at 180-200°C Density: 2.5 g/cm³ Solubility in water, g/100ml at 17°C: 39
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.
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
OCCUPATIONAL EXPOSURE LIMITS
Will turn shock-sensitive if contaminated with organic materials. Rinse contaminated clothing with plenty of water because of fire hazard.
