First, it is crucial to check your local guidelines or building codes. You should typically have one smoke detector for every floor, bedroom, and kitchen. Another rule of thumb is to install one smoke detector for every 500 feet in a home. Reviewing manufacturing recommendations, especially for interconnected devices, is also a good idea to ensure proper connection and monitoring.

No, you can’t completely fireproof a house. There is always a chance that a fire can break out inside or outside your home. Even if most of the home is built with fireproof materials, a long-burning fire can still cause damage. Still, fireproofing efforts can buy you additional time to evacuate and give you a better chance of salvaging your home after a fire rather than needing to rebuild entirely.

Your pilot light needs to be on whenever you’re using your furnace to heat your home. However, you might decide to turn it off during the summer months, when you don’t need heating. Doing this can save you a little bit of money on utility costs—just make sure you’re fine with relighting your pilot light (or hiring a professional to do it) when fall comes around and you’re ready to get cozy.

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.
