Question 3195 Deck General

The correct answer is D) launch only the windward survival capsules. This is the safest approach because in the presence of explosive concentrations of hydrogen sulfide, the safest evacuation method is to launch the survival capsules on the windward side of the rig. This ensures that any toxic gases are blown away from the evacuation area, minimizing the risk of exposure for personnel. Launching all survival capsules and liferafts, or only the leeward ones, would expose evacuees to the dangerous gas cloud. The other options, A and B, are less safe as they do not fully address the hazard posed by the explosive hydrogen sulfide concentrations on the drill floor.
