What does the term "flammable" refer to?

The term "flammable" is defined as substances that can easily ignite and burn. This classification is crucial in fire safety and prevention, as flammable materials pose a significant risk in various environments, including residential, industrial, and commercial settings.

Understanding flammability is vital for fire marshals and safety professionals, as it helps in assessing risks, ensuring proper storage, and implementing appropriate safety measures. This includes knowing which materials need special handling, what fire suppression systems may be required, and how to educate the public about the dangers of flammable substances.

In contrast, other options refer to characteristics that do not align with the definition of flammable. For instance, materials that are hard to ignite would be categorized as less hazardous in terms of flammability, while non-combustible materials do not ignite or burn at all. Additionally, items with a high boiling point may not necessarily be flammable, as flammability is more about the ease of ignition rather than the temperature at which a material transitions from a liquid to vapor.
