Question 622 Deck Safety

The correct answer is D) Oily rags are stowed in a metal pail. Oily rags can be a significant fire hazard due to the potential for spontaneous combustion. When oily rags are stored in a confined space, such as a metal pail, the heat generated by the oxidation of the oil can build up and ignite the rags, leading to a fire. This is why it is important to properly dispose of or store oily rags to prevent such incidents. The other options are not likely to cause spontaneous combustion. Option A involves a low-heat source (a light bulb) that is unlikely to ignite a clean mattress. Option B describes the proper storage of flammable liquids, which is not a spontaneous combustion hazard. Option C discusses the storage of inert cargoes, which do not pose a spontaneous combustion risk.
