An asbestos fiber was found near one of the trailers.
A decontamination center had to be built to clean them. When the decontamination center was ready the weather and rust had taken a toll and they had to be restored to be cleaned.
They have now been broken down into constituent parts and are stored in a has-mat Lv IV facility.
When Sen. Reid approves they will be encapsulated for deep burial.
I think some or all of them were made using formaldehyde, too. God forbid a homeless family should have to breathe that for a few weeks/months! Better that they should live out in the open. /s
Every house and trailer made for the previous 50 years had that stuff in the particle board, plywood, etc.
