A spark arrestor is a simple metal mesh device that prevents flammable particles from escaping from a combustion source and causing a fire. You typically find these attached to gas or diesel engines on things like cars, generators, and garden tools (lawnmowers, chainsaws, etc.). Fireplace or wood-burning stove chimneys also have spark arrestors attached to or sitting under the chimney cap to capture burning embers.

If a light switch is off, it’s very unlikely to cause a fire. For a fire to start, the switch has to be on, activating an electrical current, and the wiring must be faulty. However, the malfunctioning light switch could cause an intermittent current to move across the electrical wire. This issue could become a fire hazard with another device connected to the wire. You should replace the bad light switch as soon as you notice it or call an electrician.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

DIY cleaning is possible, but professionals ensure thorough soot removal and check for hazardous creosote buildup.
