If your Sunday barbecue suddenly turns into a fire emergency, that is not the time you want to discover that your fire extinguisher needs maintenance. This is exactly what happened to a homeowner at one of the properties I manage. Fortunately there was another extinguisher available, and that one worked well enough to avert disaster. Lesson (hopefully) learned!
Reduce the risk to yourself, loved ones and property by keeping all certifications for fire extinguishers in your community current. Also, be sure to check all Fire Alarms every five years as per the Fire Department requirements to keep everyone safe.
