There is an explosive mix of methane gas and it is very dangerous.

All we have left is hope, we are hoping for a miracle.

We didn't find anything that outwardly appeared to be dangerous or appeared to be an explosive device.

It was playing dangerous. I could still feel it even though I was playing really well and wasn't in much trouble all day. But you could see that a bad shot at the wrong time, it could cost you a lot.

Probably the most dangerous chemical they have that I'm aware of at this point ... is toluene, which can be explosive but it would be hard to ignite.

This was not from explosive materials, but from chemicals at the laboratory, maybe mixed with gas.
