I found out first hand today about the priceless value of having a smoke alarm!!! I had rushed in here to my office, in the back of my house, to get my camera to photograph a winter bird on my window sill........ I had just turned on the stove to cook my morning eggs...and I admit...I got sidetracked on my PC when I came back in here ...and yes...it was BYC..but that is beside the point.... Anyway...I was looking at post on the forum and this annoying noise was going on ...but I thought it was just my husbands stupid police scanner or maybe my new cell phone making a new sound, and I choose to ignore it, as I was reading a really interesting post.... Finally the constant beeping was gettin on my nerves...so I went in to check it out and yep...my frying pan was ablazin on the stove!! And, I , in my panic, grabbed it ...tossed it in the sink and ..DUH...turned on the water !! ....Just as the water hit the flames I remembered ...NEVER put water on a grease fire...so I grabbed a tea towel and swatted out the flames! Anyway ....all is well..but as I calmed down I realized how close I came to a major diseaster , had we not had the smoke alarms with the fresh batteries installed every DST !! ( daylight savings time ) So the moral to this story is ....Please, please , anyone who doesnt have them ...please dont let a little 9v battery, cause you to loose your home or even worse, a precious life.... All kidding aside...I thank God it was not any worse, then it could have been and just wanna share my story in hopes it helps someone else prevent a tragedy.
