 +* **FIRES. Fire extinguishers are VITAL.** I often use a lightweight arasol can because it's light weight for instant grabbing. I use "A B C" rated, not just "B C" rated, for multiple kinds of fires. The downside to an arasol extinguisher is that fires re-ignite if they aren't thickly coated in fire retardant. You have to 100% block air from the fire. FirstAlert Tundra arasol spray is excelent for small fires, because its super easy but sadly has a thin small coverage. A fire blanket is excelent but small and expensive, has to be left there a good five minutes or the fire can re-ignite. 8ft x 8ft Fire blankets or larger are perfect if you can find one. The "Kidde ABC Multipurpose Fireextinguisher"​ is fairly good at $25 dollars USD, but some Badger and Sentry products last longer and can be refilled. A everyday garden hose is super useful if it's already turned on, because a extra-hot fire spreads instantly within seconds. I keep a 3 gallon metal bucket full of water, covered with a shower cap to keep out leaves, so at any time I can splash a fire. A fire can be knocked around by a high water force, spreading bits of flaming debris.
  
 * Galvanised steel chain and some other metals put off a lethal fume, so first burn off the thin plating at a great distance where you can't smell it at all. It's preferred to never melt galvanized steel. Zinc when heated red hot, is exposed to oxides and becomes gaseous zinc oxide which can kill a human. * Galvanised steel chain and some other metals put off a lethal fume, so first burn off the thin plating at a great distance where you can't smell it at all.
