Question 1545 Deck Safety

The correct answer is A) regular checks of bilge levels. Enclosed lifeboats that have been afloat for an extended period require regular checks of the bilge levels. This is because the prolonged exposure to the marine environment can lead to the accumulation of water in the bilge, which needs to be monitored and pumped out as necessary to maintain the stability and seaworthiness of the lifeboat. The other options are incorrect because they do not address the primary maintenance requirement for enclosed lifeboats in this scenario. Opening hatches for fresh air, using ear plugs, and flushing the water spray system are not the most critical tasks for maintaining the long-term operation of the lifeboat.
