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 __________.

Correct Answer: Option B — not to leave steel or iron tools lying in or near these boats

Dissimilar metals in contact initiate galvanic corrosion, causing rapid pitting and deterioration of aluminum hulls. Leaving carbon steel or iron tools in aluminum lifeboats sets up an electrochemical cell in the presence of moisture, severely compromising structural integrity.
