If your boat is required to have a fire extinguisher, you’ll need a proper mounting bracket to hold it in place. Fire extinguishers (and all safety equipment) should be kept in an easily accessible place, like the steering area, where they will be near the operator. Be sure to mount your extinguisher away from areas where a fire could start, like the engine area.

Note: Water can put out a Type A fire, but if there is a Type B, C or D fire, water should never be used.  Water can cause flammable liquids to spread rather than putting the fire out. Additionally, water could create an electrocution hazard.
