Why would a Class A fire extinguisher not be used on a Class C fire?
Doughboy brand makes the best above ground pools. As for what is better steel, aluminum, or resin- they each have their own pros and cons. Steel is the strongest type of wall structure you can buy for an aboveground pool However, if not properly coated, it has the possibility of rusting. Doughboy puts so many coatings on their steel walls that you do not need to worry about this happening though. Resin pools will not rust, resin is plastic. They are usually more expensive than the steel pools because of how ornate the can be, plus they have to be big enough to support the water in a pool so the uprights and topseats are usually bigger than the steel ones. Regardless of which material you choose your uprights and topseats to be made out of, the actual pool wall is still made of some type of metal. Doughboy makes a great pool no matter which type you go with.
Pass on many of the small fire extinguishers that you find in small hardware stores. You will want to get a 5lb extinguisher rated for class A, B, and C fires (preferably one that can be recharged). A small 2.5lb extinguisher that is often sold in hardware stores is simply too small to use on many fires by someone that does not use them very often. A 5lb should be plenty for you without taking up too much space. The ABC rating tells you that it is good for common combustibles such as wood and paper (Class A), flammable liquids such as oil and grease (Class B), and electrical fires (Class C). By ensuring that you get one that is rechargeable, you can simply have it serviced rather than replaced if you need to use it. Look in the phone book for fire protection and you should find a nice list of local companies that will sell and service fire extinguishers. Also, spend some time learning how to use one correctly Pull the pin, Aim at the BASE of the fire, Squeeze the handle, and Sweep from side to side (remember PASS).
