In evaluating data from the WTC and the surrounding areas, the DOH is using a protective standard under AHERA (Asbestos Hazard Emergency Response Act) to evaluate the risk. This is the standard normally used to decide when children may re-enter school buildings following asbestos-removal activities. The Department of Environmental Protection requires an asbestos abatement if more than 1% of dust in a bulk sample contains asbestos fibers.

• Is it safe to run air conditioners? How do you know if your air conditioner is contaminated? If there is dust settled on the outside will it enter into the air inside? We recommend that you be diligent in replacing your air conditioner filters often since these filters serve as a trap for fibers and particulate matter. Outdoor air samples have indicated that air quality meets thecurr^t standards. However, if visible accumulations df^ebrj^re observed near the air conditioner’s intake, the accumiilations should be cleaned using vacuums equipped with HEPA filters and wet methods.

Outdoor air samples have indicated ir quality meets the current standards. However, if visible accumulations of debrig are observed near the air conditioner’s intake, the accumulations should ob-eteaned using vacuums equipped with HEPA filters and wet methods.
• How often should air conditioners filters be replaced? This depends on the manufacturer’s specifications and recommendations. Residents should check the filters on a regular basis to determine whether they need replacement. They cannot be changed to often so please error on the side of caution and replace them frequently (once a month while debris cleanup Is still occurring outdoors?)
• Can you buy a HEPA filter that will fit into an air conditioner? Some air conditioners are not compatible with HEPA filters. We are not aware of any air conditioner brands that can be retrofitted with a HEPA filter.
