170. When pumping sour crude, which gas should be tested for prior to entering the cargo pumproom to repair a leaking pump?
Sour crude is characterized by hydrogen sulfide (H2S) content, a highly toxic gas that can accumulate in enclosed spaces like pumprooms. Therefore, H2S should be tested for prior to entering the pumproom when pumping sour crude.
