Question 181Safety & Environmental - Assistant Engineer

The correct answer is C) tend to open the crack. Driving a wedge into a crack in the hull is generally not advisable because the wedge will tend to open the crack further, potentially causing more damage to the hull. Wedges are not an effective solution for repairing cracks in a vessel's hull, as they can actually exacerbate the problem by prying the crack open rather than closing it. The other options are incorrect because: A) the wedge may pull through the plating rather than hold the crack closed, B) the wedge could splinter and create additional hazards, and D) the wedge is likely to work loose over time, failing to provide a lasting repair.
