What are flammable vapors?

Flammable vapors refer specifically to the gases that are emitted from liquid substances and can ignite easily when mixed with air within a certain concentration range. These vapors are particularly dangerous because they can accumulate in low-lying areas and are often invisible, making them a significant fire hazard.

While gases released from burning materials can indeed fuel fires, flammable vapors specifically originate from liquids that have not yet ignited. Understanding the nature of flammable vapors is crucial for firefighters, as it highlights the importance of managing liquids properly and ensuring that environments are free from accumulation where vapors might build up. In firefighting scenarios, knowledge of flammable vapors is essential for creating effective strategies to mitigate fire risks and safely handle flammable substances.
