Yes, I also noticed that about Baxter.

I thought of a few others:

Roger Stanford: always a risk messing with explosives.

Alex Benedict: he lingers a little while after the gas is on.

Eric Mason: the dogs could have turned on him.

Publish or Perish - it is always risky to hire guys like Eddie Kane :D

And to trick them.
Eddie could've smelled a rat before Riley could set up his "accidental" explosion.

maybe, Short Fuse? yes he's a chemistry expert but not a munitions expert, he could have blown himself up

that is the only one I could think of that hasn't been mentioned already

Yes.
