Fireproofed carpets are treated upon or after installation. The chemical used to fireproof carpets is the same chemical used to fireproof and treat mattresses. Two of the most reasonably priced chemicals include boric acid and boric anhydride. However, there are some concerns regarding the toxicity of these chemicals to humans. Homeowners considering fireproofing a newer carpet with a warranty should first check with the manufacturer before treatment to avoid having their warranty voided.
One simple and natural way to prevent and slow down fires from spreading in pre-existing, non-fireproofed carpet is to add a wool rug. These can be found in various colors, styles and prices. Wool is naturally fire resistant. Wool is also self-extinguishing in flames, and will burn slowly in case a fire does progress. Also, wool is water and stain resistant.
Homeowners shopping for new carpet should be aware of the different fibers available. Wool fibers are the most naturally fire resistant. Nylon is the second best choice. It has a higher melting point, burns and melts slowly, which makes it more fire resistant than other carpet made from synthetic materials. Nylon is also abrasion and crush resistant. Other carpet fibers include polyester and olefin; of the two, olefin is the least fire resistant and is extremely heat sensitive.
In additional to fireproofing a home’s carpets, there are other measures to take to prevent fire. Basic fire preventative steps to take include investing in a fire extinguisher, installing and checking all the smoke alarms, purchasing fireproofed furniture, properly maintaining the home's furnace and regularly cleaning the lint trap in the dryer. Never leave candles unattended; never overload electrical wires and perform regular maintenance checks on all household appliances.
