Halotron is a clean agent fire extinguishing agent that is used to put out fires without leaving behind residue or harmful byproducts. It is environmentally friendly and widely used in situations where water or other chemical agents may be damaging or ineffective.
You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone.
