What type of material does OSHA consider wallboard/gypsum wallboard to be, surfacing or miscellaneous?
As indicated by the definitions of “Class I asbestos work” and “Class II asbestos work” presented at 29 CFR 1926.1101(b), OSHA divides asbestos-containing material (ACM) into two groups. One group of ACM consists of surfacing material and thermal system insulation. The other group of ACM material consists of material that is not surfacing material or thermal system insulation material. ACM wallboard/gypsum wallboard is material that is not surfacing material or thermal system insulation material.
