What is the preferred method for extinguishing an elevated transformer fire?

The preferred method for extinguishing an elevated transformer fire involves using a dry chemical extinguisher from an aerial device. This is because the use of dry chemical agents is effective in suppressing electrical fires that can occur in transformers, which often contain live electrical components that can pose significant hazards if approached incorrectly.

Using an aerial device allows firefighters to maintain a safe distance while effectively delivering the extinguishing agent to the fire without compromising their safety. This method minimizes the risk of electrical shock, which can be a serious danger when dealing with live equipment.

Additionally, utilizing dry chemical agents can quickly smother the flames and interrupt the combustion process, providing a rapid response to what can be a volatile situation. In situations involving elevated structures, access is often limited, making aerial devices a practical choice for reaching the source of the fire safely and efficiently.
