põlevvedelik

Põlevvedelik, often translated as combustible liquid or flammable liquid, refers to a liquid that can ignite and burn in the presence of an ignition source. The classification of a liquid as põlevvedelik is typically based on its flash point, which is the lowest temperature at which the liquid can vaporize to form an ignitable mixture in air. Different safety regulations and standards define specific flash point ranges for classifying liquids as combustible or flammable.

Combustible liquids have flash points at or above 37.8 degrees Celsius (100 degrees Fahrenheit), while flammable liquids have flash points below this temperature. This distinction is important for storage, handling, and transportation regulations to mitigate fire risks. Common examples of põlevvedelik include gasoline, kerosene, diesel fuel, and various alcohols. The vapors released from these liquids are typically denser than air and can travel along the ground to a distant ignition source, leading to flashback.

Proper storage involves using appropriate containers, ensuring good ventilation, and keeping them away from heat, sparks, and open flames. Handling procedures emphasize minimizing vapor release and avoiding static electricity. In the event of a fire involving põlevvedelik, specific extinguishing agents like foam, dry chemical, or carbon dioxide are recommended, as water may not be effective and can even spread the fire. Understanding the properties of põlevvedelik is crucial for preventing accidents and ensuring safety in industrial, commercial, and domestic settings.
