Question 1302Deck Safety70% to pass
Aluminum lifeboats are subject to damage by electrolytic corrosion (the aluminum being eaten away). In working around boats of aluminum you must be very careful _______________.
AI Explanation
The correct answer is B) not to leave steel or iron tools lying in or near these boats.
Aluminum is a highly reactive metal that can undergo electrolytic corrosion when in contact with more noble metals like steel or iron. This can cause the aluminum to be "eaten away" over time, leading to structural damage. To prevent this, it is crucial to avoid allowing steel or iron tools to come into direct contact with the aluminum boat. The other answer choices are incorrect because: A) rinsing with saltwater can actually accelerate the corrosion process, C) covering the boat does not prevent the electrolytic reaction, and D) applying an electric charge is not a standard practice for preventing aluminum corrosion in this context.
