Hazardous conditions exist which may result in spontaneous combustion when __________.

Correct Answer: Option B — oil soaked rags are stowed in the machine shop

Oil-soaked rags are a classic fire hazard due to the rapid oxidation of the oil. When piled together, the heat generated by this chemical reaction is trapped, leading to spontaneous combustion. Proper stowage in approved, self-closing metal containers is required to mitigate this significant engine room risk.
