Question 576 Deck General

The correct answer is C) 100°F. The spontaneous heating of coal rapidly accelerates at a minimum temperature of approximately 100°F. This is a well-known phenomenon in the maritime industry, where the spontaneous heating and potential combustion of coal cargo can pose a serious fire hazard. The rapid acceleration of the heating process at around 100°F is a critical temperature threshold that must be closely monitored and managed by vessel operators and cargo handlers to prevent the risk of fire or explosion. The other options are incorrect because they do not represent the recognized minimum temperature for the rapid acceleration of spontaneous coal heating. Option A (88°F) and Option B (111°F) are outside the accepted range, while Option D (119°F) is too high to be considered the approximate minimum temperature for this phenomenon.
