TITLE OF NEW CONTENT Type your content here... The addition of the definition of non-combustible (Material) is required due to the use of non-combustible (Material) in NFPA 99B. The addition of the 4th definition in the noncombustible (Material) definition is to ensure the noncombustible pertains to flooring allowed inside of a hypobaric chamber.
