When and IF you do decide to buy an extinguisher youll want to make sure its A(ordinary combustables) B(flammable/combustable liquids and gasses) C(energized electronics) and if available D(combustable metals). Those will be your denotations on the side of the cylinder. ABC is usually sufficent slow down the fire significantly. Also keep in mind that fire extinguishers are only meant to delay the fire progress. anything more than a cup full of flammable liquid can turn into quite a fire very quickly. In that instance youll do better to save yourself the burns and let the FD take care of whats left.
