The monitor read combined explosive gas. It is a Altair 4. Reads O2, CO, H2s and comb/ex. It was after cutting off the coverplate bolts that the monitor was partially inserted into the open well and it went into explosive alarm. The well haed was in a open excavation 3 foot deep.

I am not sure if this is so rare. There are several documented deaths from oxygen depletion in tanks. This is documented in our safety meetings. The level had dropped to 5% in one case. I trying to comprehed what happened onsite recently when we oxy cut off bolts above an open well. Initial gas...
What happens to the pressure inside the tank when the oxygen is used in the rusting process. Are the oxygen atoms replaced or does the internal pressure drop? I would imagine the volume change is significant going from 20% down to 5%.
Hello,
I was recently preparing a well for a rig over. Initial gas monitoring read 0. On removal of a temporary cover plate by hot cutting. After removal of cover plate the gas tester was inserted into an open well and recorded an explosive atmosphere. My question is a general estimate of what...
