Recent published reports have stated that tremolite asbestos may be a contaminant in certain brands of vermiculite.

Roofing Cement Gasket material is often ACM.

Roofing Materials:

Roofing Cement Asphaltic roofing products, such as this roofing cement, often contains asbestos. OSHA and the Wisconsin DNR have established work practices for roofing repair and roofing abatement projects.

Asbestos Core Doors:

Asbestos Core Fire-Rated Door Photo on the left is the asbestos core of a fire-rated door. We've discovered both chrysotile and amosite asbestos in these cores; in most cases, the core is highly friable if disturbed. Other non-fire rated doors on campus, both wood and metal, have also had asbestos insulation.
Asbestos Core Fire-Rated Door Specialized training and work practice exposure control measures are required for UWM personnel performing maintenance on asbestos core doors.

For renovation projects, unless a door is determined to be asbestos-free, the door shall be disposed as asbestos waste.
