Question 2921 Deck General

The correct answer is D) on the drill floor and liquid mud handling areas. The most probable location to encounter explosive and flammable gases on a MODU (Mobile Offshore Drilling Unit) would be on the drill floor and in the liquid mud handling areas. This is because these areas are where drilling operations take place, and drilling fluids, gases, and other potentially flammable substances are handled. Regulations, such as those set by the International Maritime Organization (IMO) and the International Organization for Standardization (ISO), require strict safety measures and hazard control procedures in these specific areas to mitigate the risks of explosions and fires. The other options are incorrect because A) any location is too broad, B) machinery spaces may have potential ignition sources but are not the most likely areas, and C) bulk storage tanks, while containing flammable substances, are typically designed and maintained to prevent the accumulation of gases.
