4.0 RECOMMENDATIONS <br />P'�CAA requires that ACM must be removed before demolition or re-modeling that will <br />otherwise disturb the material. A licensed asbestos-abatement contra�tor employing <br />certified asbestos personnel must complete the removal of ACM. Notification to the <br />Washington State Department of Labor and Industries (L&� and PSCAA is required before <br />asbestos abatement. Furthermore, notifica�ion of the presence of ACM to employees, <br />contractors, and space tenants who may come in contact or disturb the material is required <br />by the Washington State Department of Labor & Industries (L&n. <br />Wallboard joint compound was found to contain approximately 2% asbestos in one of two <br />wallboard samples in the residence located at 6815 Beverly. As a composite, the wallboard <br />system contains less than 1% asbestos, and is therefore not considered and asbestos- <br />containing material by PSCAA. Nevertheless, the WashingYon State Department of Labor <br />and Industries (LBcn requires asbestos-trained workers utilizing approp►iate respiiatory <br />protection, among other requirements, when disturbing the material. Tl�e practical effect of <br />L&I's position is that the wallboazd should be managed by the abatement contractor. <br />In our opinion, additional suspect ACM may be discovered during the course of abatement. <br />Newly discovered suspect materials should be sampled by an AHERA-certified inspector, <br />and abated prior to building demolition if found to be ACM. G-Logics also recommends <br />that an asbestos-project specification be prepared before abatement work. The purpose of <br />the specification is to solicit bids from qualified contractors, define the scope of work, and <br />establish appropriate work procedures. <br />Several fluorescent light fixtures are present within the firehouse. Although not part of our <br />scope of work, several light ballasts associated with the light fixtures were visually <br />inspected during the asbestos survey, and no reference to polychlorinated biphenyls (PCBs) <br />was found on any of the inspected ballasts. Fluorescznt light ballasts not labeled as <br />containing "no PCBs" usually contain these compounds. It will be necessary to remove <br />potential PCB-containing electrical equipment and mercury-containing light tubes before <br />building demolition. The asbestos abatement contractor will likely be equipped to remove <br />and manage the light ballasts and light tubes and should be requested to do so. <br />Oi-0105•A-RT.doc <br />Copyright 2U01 GLogics, Inc. <br />Page 4 of 5 <br />� SIO�%CS <br />;�l <br />� <br />� <br />R`� <br />a <br />1. <br />� <br />� <br />t <br />ii <br />4. <br />! <br />� <br />M{ <br />� <br />� <br />
