Then I went back to check the suspected exchanger.....but smelled nothing this time.
Well.....my nose was "killed" when I got the first whiff. In the next 30 minutes, I had the worst headache ever and felt really bad. I felt very bad for the next 6 or 8 hours.

We have H2S where I work due to water flood injection. it kills your sense of smell, then you don't know you are smelling any longer. You think you are in the clear since you no longer smell it.
Those vessels should have been drained, purged and tested before anyone went in, or even cracked a manway.
