Question 151Safety & Environmental - 1st Asst/Chief70% to pass
When pumping sour crude, which gas should be tested for prior to entering the cargo pump room to repair a leaking pump?
AI Explanation
The correct answer is C) Hydrogen sulfide.
When pumping sour crude, the primary hazard is the presence of hydrogen sulfide (H2S), a highly toxic and flammable gas. Before entering the cargo pump room to repair a leaking pump, the atmosphere must be tested for H2S, as exposure can be life-threatening. The other options, such as benzene, carbon monoxide, and tetraethyl lead, are not the critical gas to test for in this specific scenario involving sour crude.
