| 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.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: P3 filter respirator for toxic particles).

| 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 systemand 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. | ||
