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.

They don’t have an expiration date on the canister, but you can check the manufacturing date on the “UL” nameplate near the classification information.

You'll want to make sure the gauge needle is in the green section, and if a hose or nozzle has been used or damaged, you need to replace it.

If you cannot replace the flue you have removed, call a chimney repair professional immediately.
