I've done inspections and repairs inside fuel tanks that had a nitrogen generating system; We wear a gas detector that constantly monitors stuff like 02 levels, vapor concentrations, ionizing radiation etc. We dont even enter before taking a reading. If 02 gets below 18.5% or above 22% it will start flashing and sounding a (quite loud) alarm. This is worn in addition to all kinds of rules about tank entry: Gotta have a spotter make contact with you every 5 min, gotta have forced air ventilation or SCBA, gotta notify security of the entry operation so they can direct the rescue personnel if something goes wrong, etc.

It's fun work, imo. But yeah, it is actually quite dangerous.
