its not enough that you have fire extinguishers, you must also make sure your family members know how to use them. i was a safety engineer, and part of my departments scope is to train people in handling fire extinguishers. you'd be surpised as to the number of ways people MIShandle fire extinguishers.

if you're company offers safety programs, i suggest you take advantage and learn. then you can teach your family members as well.
