What is a good technique when using a fire extinguisher on a boat?

A good technique when using a fire extinguisher on a boat is to remember the acronym PASS: Pull the pin, Aim low at the base of the fire, Squeeze the handle, and Sweep side to side. It's crucial to approach the fire from an upwind position to avoid smoke and flames. Additionally, ensure you have a clear escape route in case the fire intensifies. Always prioritize safety and consider evacuating if the fire cannot be controlled quickly.
