18 Asbestos Safety Manual Environmental Health and Safety Minimizing Potential Exposure Damage and Deterioration When ACM degrades or is damaged, it may release asbestos into the air. • Avoid physical damage or disturbing ACM on ceiling, pipes, or floors when moving furniture, equipment, or supplies. • Do not hang plants or pictures from structures covered with ACM. • Do not drill, sand, or scrape materials that contain ACM. • Do not attempt to clean any material that appears to contain asbestos. • Contact your supervisor immediately to arrange proper cleaning of any material that you suspect may contain asbestos. • Cleanup of ACM should only be done using a High Efficiency Particulate Air (HEPA) vacuum and/or wet methods by properly trained personnel. Floor Care In order to minimize the potential for exposure to asbestos during floor care, the following practices are recommended: • Never sand or scrape asphalt or vinyl flooring that contains asbestos. • Always strip floor finishes using wet methods and the lowest abrasion pads possible. (Never use coarse black pads on asbestos flooring.) Always use speeds less than 300 revolutions per minute (rpm). • Burnish or dry-buff asbestos containing flooring only when it has enough finish so that the pad cannot contact the asbestoscontaining material. • Do not dust, dry-sweep, or vacuum dirt or debris in an area that contains damaged thermal asbestos insulation, surfacing or deteriorated ACM. Use only wet methods or HEPA filtered vacuums. Deterioration Note: Report evidence of deterioration, water damage, or delamination to EH&S at (515) 294-5359
