Fire retardant = fire proof.

• Flame retardant (OSHA) - a substance that will generally self extinguish in a vertical flame test or assist other materials in resisting flame effects.
• Fire retardant (Textile Ind) - Fabric that, without chemical additives, will inhibit the spread of fire (ie fail to ignite under most household instances and self extinguish under others)
• Flame retarded (NFPA)- non FR material that has been chemically treated to act like one.
• Fire resistant (textile) - fabric, treated or not, that will self- extinguish in horizontal burn but fails vertical test (think carpeting).
• Flame proof (NFPA) - material that is manufactured to a specific chemical state making it unable to produce a flame at any heat. (Such fabrics will generally disintegrate under high heat)
• Fire proof (alchemical) - a mythological state of being impervious to fire. Recent studies of metallurgy, astronomy, and nuclear fusion have completely debunked this myth on all levels. Everything melts at SOME temperature.
