What is a hydrocarbon fire?
Hydrocarbon Fire (HF) – Hydrocarbon fires are caused by combustible liquid such as oil and gas. Carbon and hydrogen make up hydrocarbons and they do not have affinity for H2O (water). Within 5 minutes, a hydrocarbon fire can heat up to 1000°C and peaks to 1100 °C in a short time.
How do you put out a hydrocarbon fire?
The right way to extinguish a hydrocarbon fire is to use an agent that will effectively isolate the fuel source or to stop the flow of the combustible liquid. It must be able to inhibit the release of the flammable vapours as well as delay the combustion process because this class of fire re-ignites easily.
What are the 4 types of fire extinguishers and their uses?

- Class A extinguishers will put out fires in ordinary combustibles such as wood and paper.
- Class B extinguishers are for use on flammable liquids like grease, gasoline and oil.

Is green or blue fire hotter?
Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. For example, the element lithium will produce a pink flame, while the element tungsten will produce a green flame.
Is Green Fire toxic?
Green flame can be caused by copper salts or corroded copper parts contaminating the flame with copper ions. This can “naturally” happen, and the minute amount of copper is harmless. However if someone intentionally put larger amount of toxic copper salts there, that might be dangerous.
