Emergency treatment
Hi Mahmoud - a good clue would be to see what the army does in such situations. Many use portable filtration / adsorption units which are based on Diatomaceous Earth (DE) filtration. I think these are suitable for immediate response and then perhaps some of the other short term suggestions may become better. See if you can get insight from military sources.
Hope this helps.
