It seems you've mentioned "900 kg toner" and "Emergency Chlorine Scrubber" together. It's not entirely clear what you're referring to, as toner typically relates to printers and photocopiers, while an emergency chlorine scrubber is a safety device used to mitigate the release of chlorine gas in industrial settings.
If you could provide more context or clarify your question, I'd be happy to help with any information or guidance you might need regarding toner or emergency chlorine scrubbers.
