Hi CB.. I noticed in your posts that you have reliable enough info source and I think the PFC statement it's not in contrast with them

"They didn't measure it , it was a skim on the surface
Actually it was the fumes that were so strong that they could not go in there ---- "In there" does not specify a room or a closed place.It's also could mean a "pool" were the mud was stocked and with strong fumes, even an open place can be dangerous without BA ---- without breathing apparatus,
So they didn't collect any sample unfortunately --- No BA on spot so that's the reason why they din't collect samples!!---."
