70% to passHazardous conditions exist which may result in spontaneous combustion when _______________.
Apowdered aluminum is stowed dry
Boil soaked rags are stowed in the machine shop
Cdry metal turnings accumulate
Dall of the above
AI Explanation
The correct answer is B) oil soaked rags are stowed in the machine shop. Oily rags can spontaneously combust due to the heat generated by the oxidation of the oil. This is a well-known fire hazard in machine shops and other areas where oily rags may accumulate. The other options, while potentially hazardous, do not specifically involve the risk of spontaneous combustion. Powdered aluminum (A) can be a fire hazard, but it requires specific conditions to spontaneously ignite. Dry metal turnings (C) can also be a fire hazard, but again, spontaneous combustion is not the primary concern. The correct answer, B, specifically addresses the risk of spontaneous combustion due to the storage of oil-soaked rags.
