Lewith Tankers Exam 3 Practice

Oily rags can generate heat from oxidation and ignite if they’re left exposed. Keeping them in a metal container with a tight, self-closing lid confines any heat and limits oxygen, drastically reducing the chance of spontaneous ignition. Disposing overboard is hazardous and illegal in many settings because it can pollute the water and spread fire risk or embers. Burning on deck is risky too—it can get out of control, produce toxic smoke, and endanger the vessel and crew. So, the safest and most effective practice is to store oily rags in a self-closing container and never dispose of them overboard.
