| 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 contact with combustible substances.
|
In case of fire in the surroundings: use appropriate extinguishing media.
|
| EXPLOSION |
|
|
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
|
| Skin |
|
Protective gloves.
|
First rinse with plenty of water, then remove contaminated clothes and rinse again.
|
| Eyes |
Redness. Pain.
|
Safety spectacles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Rapid pulse. (See Inhalation).
|
Do not eat, drink, or smoke during work. Wash hands before eating.
|
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: HYGROSCOPIC, WHITE TO YELLOW SOLID IN VARIOUS FORMS CHEMICAL DANGERS: May explode on heating above 530°C. The substance decomposes on contact with acids producing toxic fumes (nitrogen oxides). The substance is a strong oxidant and reacts with combustible and reducing materials causing fire and explosion hazard. The solution in water is a weak base. Reacts with aluminium, ammonium compounds, amines. OCCUPATIONAL EXPOSURE LIMITS: 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. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes. The substance may cause effects on the cardiovascular system and blood, resulting in lower blood pressure and the formation of methaemoglobin. Exposure may result in death. The effects may be delayed. Medical observation is indicated. | ||
