| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible but enhances combustion of other substances. Explosive. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO contact with combustibles or reducing agents.
|
Water in large amounts. NO other extinguishing agents. In case of fire in the surroundings: use flooding amounts of water in the early stages.
|
| EXPLOSION |
Risk of fire and explosion under confinement and high temperatures.
|
|
Evacuate danger area! In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Cough. Headache. Sore throat. See Ingestion.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
|
| Skin |
Redness.
|
Protective gloves.
|
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
|
| Eyes |
Redness. Pain.
|
Safety goggles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Abdominal pain. Blue lips or fingernails. Blue skin. Convulsions. Diarrhoea. Dizziness. Vomiting. Weakness.
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Refer for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS, HYGROSCOPIC TO WHITE SOLID IN VARIOUS FORMS CHEMICAL DANGERS: Heating may cause violent combustion or explosion. The substance decomposes on heating or producing toxic fumes (nitrogen oxides.) The substance is a strong oxidant and reacts with combustible and reducing materials. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. 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 skin and the respiratory tract. The substance may cause effects on the blood, resulting in formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. | ||
| PHYSICAL PROPERTIES | |||
|
Decomposes below boiling point at about 210°C Melting point: 170°C Density: 1.7 g/cm³ Solubility in water, g/100 ml at 20°C: 190 |
|||
| ENVIRONMENTAL DATA | |||
|
This substance may be hazardous to the environment; special attention should be given to water quality.
| |||
| NOTES | |||
|
Becomes shock-sensitive when mixed with organic materials. Rinse contaminated clothes (fire hazard) with plenty of water. Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Card has been partly updated in October 2005. See section Emergency Response.
