put near the engine because the engine of the boat is a fire hazardous place
and this is the area where a fire could start.
The fire extinguisher should be installed properly using a mounting
bracket to hold the extinguisher in place. There are different types of
extinguishers that should be installed in the boat, these are type A, B, and C
extinguishers. Type A extinguishers can turn off the fire caused by combustible
solids like wood and paper. Type B extinguishers can turn off fire caused by
gasolines, oil, and greases. While Type C extinguishers can turn off fire
caused by an electrical problem.</span>
