Guidance on Safe Use
Administrative data
First-aid measures
Take for medical treatment:
After contact with skin: Brush off Phosphorus pentoxide from the skin and there after wash with plenty of cold water.
After contact with eyes: In case of contact with eyes rinse thoroughly with plenty of water and seek medical advice
After ingestion: Summon a doctor immediately. Do not induce vomiting. When swallowed, allow water to be drunk.
Drink Aluminium oxide suspension.
Advice to doctor:
Symptoms: Coughing; Shortness of breath
Hazards: Risk of pulmonary oedema
Treatment: In case of lung irritation, treat first with Auxiloson i.e. Pulmicort - Dosing aerosol (Auxiloson
and Pulmicort are registered Trade Marks).
Fire-fighting measures
for firefighting: Wear respiratory protection when fighting fires
Accidental release measures
Dispose of contaminated
Handling and storage
Further information on storage conditions: Keep container tightly closed
Protect from atmospheric moisture and water
Storage stability: In the original, unopened packages protected from moisture, product can be stored for at
least 12 months
