The NFPA model codes and International Residential Code (IRC) mandate that all new one- and two-family homes have fire sprinkler systems. However, all municipalities are different. The best way to determine if your municipality requires fire sprinklers is to contact your state fire marshal’s office. One reason to install a fire sprinkler system is that it’s the first line of defense in putting out a fire and alerting your family of emergencies.

Call 911 immediately. If you have a fire extinguisher or fire blanket near the laundry room, you can attempt to extinguish the fire, but don’t open or touch the dryer. If you can’t put the fire out, evacuate yourself, your family, and your pets from the house, closing the laundry room door behind you. Turn off the electricity to your home via the outside fuse box, then wait for the fire department. After a dryer fire, have your home’s electrical system inspected to make sure there isn’t any damage.

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.

Yes, fire extinguishers eventually expire. However, the good news is that a properly stored fire extinguisher can last a decade or longer. 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. Maintenance will also give your fire extinguisher longevity. Check the gauge at the top of the extinguisher every month. 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.
