TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
|
|
In case of fire in the surroundings: all extinguishing agents allowed.
|
| EXPLOSION |
|
|
|
 | |||
| EXPOSURE |
|
AVOID ALL CONTACT!
|
|
| Inhalation |
Burning sensation. Cough. Shortness of breath. Sore throat.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Half-upright position. Refer for medical attention.
|
| Skin |
Skin burns. Pain. Blisters.
|
Protective clothing.
|
Rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
|
| Eyes |
Redness. Pain. Severe deep burns.
|
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. Burning sensation. Shock or collapse.
|
Do not eat, drink, or smoke during work. Wash hands before eating.
|
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. 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 (extra personal protection: complete protective clothing including self-contained breathing apparatus).
|
|
| EMERGENCY RESPONSE | STORAGE |
|
Separated from strong acids. Dry. Well closed.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes including phosphorous oxides. The solution in water is a strong base, it reacts violently with acid and is corrosive. Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of dust may cause lung oedema (see Notes). |
| PHYSICAL PROPERTIES | |
|
Melting point (decomposes): 75°C
Relative density (water = 1): 2.5 Solubility in water, g/100 ml: 8.8 |
|
| ENVIRONMENTAL DATA | |
|
|
| NOTES | |
|
The symptoms of lung oedema 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. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
