Asbestos Containing Material (ACM) Image Page-Miscellaneous Materials
Vermiculite:
 |
The vermiculite sample on the right (not from the bag of vermiculite on the left) has trace amounts (less than 1%) of actinolite. Recent published reports have stated that tremolite asbestos may be a contaminant in certain brands of vermiculite. |
 |
Gasket Materials:
 |
Gasket material is often ACM. |
Roofing Materials:
 |
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:
 |
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. | |
 |
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. |
 |
Oakum:
| This material is oakum pipe joint packing, which is used to seal sanitary sewer pipe joints. Sample #90813K19 was negative, however other oakum varieties in our buildings have tested positive for asbestos and were highly friable (e.g., sample #70102K01, >75% chrysotile). |  |
| Examples of roofing material (felt paper, built-up felt paper and tar, and perlitic material in tar). Of these particular samples the felt paper (K45) and built-up sample (K46) are ACM. The EPA/DNR have specialized work procedures for roofing work involving ACM. |  |
