In another life I had to take aircraft crash response training, and was in charge of recovery (salvage, battle-field repair etc). The response to an aircraft with composite materials is totally different. With normal construction we could get to work as soon as the fire, was out and any hazardous liquids were taken care of. Crashes involving damage to composite structures required that the damaged areas be sprayed down with a varnish like chemical by the same troops who handle Chemical weapon response (they had special suits). Then there would be air particulate tests before we could move in. Here is a military study: http://www.dtic.mil/dtic/tr/fulltext/u2/a420193.pdf http://www.dtic.mil/dtic/tr/fulltext/u2/a420193.pdf
