|
General information: Rapid action is called for. First-aid personnel: ensure self-protection! Immediately summon doctor (mentioning hydrocyanic acid poisoning). If breathing stops: immediately apply mechanical ventilation, if necessary also oxygen. After skin contact: wash off with plenty of water. Remove contaminated clothing. After eye contact: rinse out with plenty of water with the eyelid held wide open. After swallowing: if victim is still conscious, make him drink plenty of water, induce vomiting, administer activated charcoal (20 - 40 g in 10% slurry). Immediately summon doctor. Instructions for the doctor: Keep antidotes ready ( sodium thiosulfate ; dimethylaminophenol ; Cobalt-EDTA |

| 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. |
