Known Friable and Non-Friable Asbestos

In general, buildings constructed prior to 1979 are likely to have been built using asbestos containing materials (ACMs). ACMs are often found in surfacing materials such as fireproofing, sprayed on ceilings, vinyl floor tiles and mastic (adhesive), or in thermal system insulation such as pipe insulation and wrappings. Renovation projects on campus often include removal or encapsulation of ACMs by trained and licensed specialists.

Asbestos is a commercial term applied to a number of silicate minerals that readily separate into thin, strong, flexible fibers and has been identified by the United States Environmental Protection Agency and the State of California as a carcinogen. There are two generally descriptive classifications of ACMs: friable and non-friable. Friable materials are those capable of being crumbled and reduced to powder, when dry, by the use of hand pressure. Non-friable ACMs are generally not considered to be a health risk since the fibers are normally bound or contained in the building material itself. However, a fiber release can occur when these materials are broken or damaged. Examples of non-friable ACMs include vinyl floor tile, the mastic used to glue the tile to the floor or ceiling, window glazing, and transite paneling.

Intact and properly maintained ACMs do not create an unsafe condition unless disturbed and released. Therefore, in order to ensure the health and safety of building occupants and the public, any work or activity that might disturb ACMs must be performed only by certified and trained personnel. Sawing, sanding, cutting, moving, drilling, boring or otherwise disturbing ACMs may present a health risk if it causes asbestos fibers to be released where they can be inhaled or ingested. Prior to performing any such work or activity, it is very important to contact the Harvey Mudd College Office of Facilities and Maintenance (F&M) in order that a review for possible ACMs can be done and written approval provided for the safe commencement of the work or activity. Additionally, deteriorating ACMs should be immediately reported to F&M.

As required by law, extensive surveys by specialists were conducted in order to determine the location and amount of ACMs in campus buildings that were constructed prior to 1979. These surveys and reports are on file and available for inspection at the Harvey Mudd College facilities and maintenance office, lower level of Platt Campus Center. When ACMs are identified, they are placed on a cumulative list for periodic inspection and maintenance until they are removed during renovation or through an abatement program. An Asbestos Operations and Maintenance Plan is regularly updated to provide current information for the proper maintenance and handling of ACMs located in campus buildings. A review of the materials may be made by contacting the Harvey Mudd College facilities and maintenance office at 909/621-8226.

In addition, when a building owner has knowledge of the presence of ACMs in their buildings, they are required to provide specific information relating to ACMs to employees and other building occupants. Below is a list of HMC buildings that contain ACMs, including the general location and application of the ACMs. In publicly-accessible areas, ACMs are bonded or locked in the building materials, painted over, enclosed or encapsulated so that fibers are not released. Typically, this would include items such as floor tiles and mastic adhesive used to secure them to the floor or insulation within walls or doors. In restricted public access areas, such as mechanical or boiler rooms and on structural steel, ACMs are typically found in insulation and fireproofing materials.

The College believes that the immediate correction of hazardous conditions, including the removal of ACMs during renovations and the effective implementation of the Asbestos Operations and Maintenance Plan through F&M, will provide an asbestos-safe campus environment. Your cooperation is appreciated.

If you have questions or would like more information about ACMs, please contact the Harvey Mudd College F&M office at 909.621.8226.
