| 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.
|
Foam, water spray, powder.
|
| EXPLOSION |
Finely dispersed particles form explosive mixtures in air.
|
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
|
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Cough.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
Redness. Pain.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
|
| Eyes |
Redness. Pain.
|
Face shield 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.
|
| Ingestion |
Abdominal pain. Nausea. Vomiting.
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Personal protection: A/P2 filter respirator for organic vapour and harmful dust.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: HYGROSCOPIC, COLOURLESS CRYSTALS OR WHITE CRYSTALLINE POWDER PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic and corrosive gases including formaldehyde, ammonia, hydrogen cyanide and nitrogen oxides. The solution in water is a weak base. Reacts with strong oxidants and strong acids producing toxic and corrosive gases. Attacks aluminium and zinc. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: IIb (not established but data is available); sensitization of skin (Sh); (DFG 2004). |
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 when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is mildly irritating to the eyes and the skin. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. | ||
| PHYSICAL PROPERTIES | |||
|
Sublimation point: about 260°C Density: 1.33 g/cm³ Solubility in water: good Relative vapour density (air = 1): 4.9 |
Flash point: 250°C c.c. Auto-ignition temperature: 390°C Octanol/water partition coefficient as log Pow: -2.84 | ||
| ENVIRONMENTAL DATA | |||
|
| |||
| NOTES | |||
|
The substance may release formaldehyde. See ICSC 0695 Formaldehyde. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Card has been partly updated in April 2005. See section Occupational Exposure Limits. | |||
