| Further toxicological information |
|
After inhalation of dust: damage of respiratory tract Possible symptoms: bronchitis , pneumonia After skin contact: burns Causes poorly healing wounds. After eye contact: burns Risk of corneal clouding. Risk of blindness! After swallowing: Burns in oesophagus and stomach. Risk of perforation in the oesophagus and stomach. |
| Further data |
| The product should be handled with the care usual when dealing with chemicals. |
| 12. Ecological information |
|
Ecotoxic effects: The following may develop after reaction of the product with water: phosphoric acid Toxic for aquatic organisms Harmful effect due to pH shift. Further ecologic data: Degradability: COD: 0 mg/g Depending on the concentration, phosphorus compounds may contribute to the eutrophication of water supplies. Do not allow to enter waters, waste water, or soil! |
| 13. Disposal considerations |
| Product: |
| There are no uniform EC Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member countries through corresponding laws and regulations. We recommend that you contact either the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste. |
| Packaging: |
| Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled. |
