| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames.
|
Powder, water spray, foam, carbon dioxide.
|
| EXPLOSION |
Finely dispersed particles form explosive mixtures in air.
|
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST! STRICT HYGIENE!
|
|
| Inhalation |
Blue lips or finger nails. Blue skin. Confusion. Convulsions. Cough. Dizziness. Headache. Nausea. Sore throat. Unconsciousness.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
MAY BE ABSORBED!
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
|
| Eyes |
Redness. Pain.
|
Safety goggles, or eye protection in combination with breathing protection.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: May explode on heating. On combustion, forms nitrogen oxides. The substance decomposes on heating producing toxic fumes including nitrogen oxides. Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin 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 irritates the eyes and the skin and the respiratory tract. The substance may cause effects on the blood, resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. | ||
