Fire extinguishers can be a small but important part of the home fire safety plan. This holds true only after you've already installed working smoke detectors and a safe home fire evacuation plan.
Don't wait to think about disaster until you're dealing with one. In the hurried confusion, you're likely to miss important items as you prepare your home or leave to find shelter.
For safety's sake, look through your home often. Keep an eye out for not-so-obvious hazards.
