Which of the following statements is true about flammable materials?

All flammable materials possess an autoignition temperature, which is the minimum temperature at which they will ignite in the absence of an external spark or flame. This characteristic is vital for understanding the hazards associated with handling and storing flammable substances. The autoignition temperature varies among different materials, including solids, liquids, and gases, making it an essential factor in safety protocols for HAZMAT operations.

Understanding that all flammable materials have an autoignition temperature allows safety professionals to recognize the risks involved at various temperature levels, facilitating appropriate measures to prevent accidental ignition. Recognizing this inherent property supports effective risk management and safety planning across various applications involving flammable materials.
