Disposable fire extinguishers are good for anywhere from 10 to 12 years, but check the documentation that accompanied your specific model to make sure. Additionally, there are rechargeable models out there that last 12 to 20 years, but they require a professional inspection every six years.

According to the National Fire Protection Association’s Code NFPA 25 (titled “Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems”), private fire hydrants must undergo inspection once per year, with an accompanying flow test and any necessary maintenance performed on the same schedule. Keep in mind that your town, city, or county may adopt more or less strict testing requirements. 

After a house fire, you should not reenter your home unless the fire crew has told you it’s safe to do so. In the longer term, you should not attempt to make repairs to the house on your own. Professional crews are trained to clean up after a fire (including smoke and soot damage), dry out any water damage from the firefighter crews, and make the necessary structural, plumbing, and electrical repairs—and this is all likely covered by insurance.

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features.
