Ill vouch for that. I think this is one of the most important considerations along with PLACEMENT within the home.I remember reading that you are more likely to loose everything in a fire than to theft. So a good fire rating from a reputable company is important.
Most fires start in the kitchen or a centralized area full of electronics etc. I dont believe I have EVER seen an accidental fire start in a bedroom. Kitchens, for the most part, are located furthest from the bedrooms and even in fires that destroy a home 80-90% (before we can get there) its amazing how well (closed) closet spaces survive along with the clothing. Ruined by smoke and water ,yes, but not the heat.
Think about it as layers of clothing, Im going to place my gun in a safe layer, then Im going to layer the safe within a closed closet, which naturally places it furthest from "said" heat source.
And since I breached that subject....todays tip.
Those newfangled electronic refrigerators. If you have one of the new fancy ones I encourage you to place a smoke detector on the back of it somewhere. I am amazed at how many recent (5 years) fires have been caused by the damn fridge. Those things seem to catch on fire all the time.
