Aabestos Air Sampling
20 air samples were taken and analyzed by an accredited asbestos laboratory using transmission electron microscopy (TEM). TEM analysis is very accurate for finding even trace amounts of asbestos fibers present in the air.
The United States Environmental Protection Agency (EPA) has established a protocol for determining whether school areas are safe for re -occupancy after completion of asbestos abatement projects. This proccdurc is covered by EPA 40 CFR Part 763, Asbestos-Containing Materials in Schools. The procedures state that the average asbestos airborne fiber in the abated work area level
be less than 70 asbestos structures per square millimeter (AS/mm'). must
The laboratory results from the testing on September 20, found no asbestos structures present in 17 of the samples. 3 samples had two or less asbestos structures prescrit arid the levels were well below the allowable 70 AS/mma. Reference the attached laboratory results from EMSL Analytical.
The 3 areas with detectable asbestos fibers are heavily used by the rescue and recovery personnel. The asbestos fibers are probably carried into the building from their clothing. As a precaution, prior to the college re-opening, these areas should be thoroughly wet cleaned.
Asbestos Surface Sampling
The accredited asbestos laboratory analyzed 67 surface dust samples using polarized light microscopy (PLM). 36 Samples were from the air handling unit outdoor air damper sections and plenums. None of the samples were identified as asbestos containing materials (ACM). An:ACM is defined as a material with greater than one percent asbestos. Levels less than one percent are not regL.thttcd.
Six samples found to have trace (i.e., less than 1%) asbestos content. were
Similar to the air samples, detectable asbestos fibers were limited to areas that are heavily used by the rescue and recovery personnel. As a precaution, prior to the college re-opening, these areas should be thoroughly wet cleaned (HEPA vacuum carpeting).
