Extinguisher tips

  • Fire extinguishers are important fire protection tools. However, it’s vital to know the fire type and extinguisher class before attempting usage. Using the wrong extinguisher on the wrong fire can make the fire worse and cause life-threatening injury.
  • It’s extremely important for all members of the household, babysitters, housekeepers and any other potential user to know how to safely and correctly use the fire extinguisher. Since most will not be using an extinguisher on a regular basis, it’s also important to periodically review the instructions.
  • Because fires may often involve a combination of elements, most fire protection experts recommend a fire extinguisher with an ABC rating.
  • Experts recommend that a medium-sized fire extinguisher be placed in the kitchen and garage. An extinguisher should also be placed on each additional floor of the home.
  • All extinguishers should be inspected annually and maintained by a professional fire equipment supplier. If not properly maintained, your unit might not discharge when needed. There’s also the risk of it rupturing when pressurized, which can result in serious injury.
  • Having fire extinguishers in the home may reduce the cost of home insurance. Contact us find out if a discount for fire loss-prevention measures is offered.
