Question

which of the following reasons is the best reason for not letting oily rags pile up in an open storage bin.
o causes a foul odor
o makes the work area look messy
o oil will seep onto the floor
o poses a fire hazard

Explanation:

Oily rags can undergo spontaneous combustion. When they pile up in an open storage bin, the heat generated from oxidation (a chemical reaction) can build - up. If the temperature reaches the ignition point of the oil or the rag material, it can cause a fire. While "Oil will seep onto the floor", "Makes the work area look messy", and "Causes a foul odor" are also possible issues with oily rags, the fire hazard is the most serious and potentially life - threatening consequence.

Answer:

Poses a fire hazard
