If a cargo of kerosene were considered "too lean" to explode, then it must be _______________.
AI Explanation
The correct answer is A) below the "explosive range".
If a cargo of kerosene is considered "too lean" to explode, it means the fuel-to-air ratio is below the lower explosive limit (LEL) of the substance. The explosive range is the range of fuel-to-air ratios where the mixture can ignite and explode. When the mixture is below the LEL, it is considered "too lean" to explode, as there is not enough fuel present to support combustion. Therefore, a cargo of kerosene that is "too lean" to explode must be below the explosive range.
The other options are incorrect because B) within the explosive range would mean the mixture is ignitable, and C) above the explosive range would indicate a fuel-rich mixture that is also not explosive.
