Question 197Safety & Environmental - QMED70% to pass
The process that occurs when heat is generated by a chemical reaction within a substance and continues to a point of ignition is known as _______________.
AI Explanation
The correct answer is C) spontaneous combustion.
Spontaneous combustion occurs when heat is generated within a substance through a chemical reaction, and this heat continues to build up to the point of ignition, without an external source of heat or flame. This is different from chemical ignition (A), which requires an external ignition source, or chemical combustion (B), which is the general term for the chemical reaction that releases heat and light. Radiation ignition (D) refers to the ignition of a substance due to exposure to radiant heat, not an internal chemical reaction.
The process of spontaneous combustion is an important consideration in the safe storage and handling of certain materials on board vessels, as outlined in the regulations for the US Coast Guard Captain's License Examinations.
