The MPCA Demolition notification(attached)must be sent in 10 days prior to demolition. The thermostats and fluorescent light bulbs must be removed and disposed of properly because of the mercury concem. The smoke detectors need to be removed because of radiation concerns. The water heater, water softener, air conditioner, furnace, kitchen appliances,washer and dryer needs to be removed prior to demolition. Current Environmental Protection Agency (EPA) statutes mandate control measures for friable (easily pulverized) asbestos-containing materials. Non-friable materials (for example, tar paper, or floor tile or mastic) do not pose an immediate exposure risk unless they are cut, torn, sanded or otherwise abraded. Because non-friable materials have the potential to become friable during certain activities,friable or non-friable materials have be�n identified in this building. EPA's Asbestos Hazard Emergency Response Act (AHBRA) was used as a guidance document for bulk sampling procedures, sample analysis, and locatiop selection. An AHERA asbestos trained building inspector participated in the building inspection. BULK SAMPLING METHODS Asbestos bulk sampling was performed, sampling included collection of material samples and analysis of bulk samples for asbestos percentages utilizing polarized light microscopy(PLM). A walk-through survey of the building was first conducted to identify homogeneous areas and develop a bulk sampling and inspection strategy. For each homogeneous area sampled,two criteria were used to determine sample locations: 1)The sample site must be representative of the homogeneous area, 2) A random element to prevent bias from entering the results was exercised in sample site selection. Sampling protocol was as follows. Amended water consisting of water and a surfactant (soap solution) was misted on the sample site before, during aild after the sampling process. This served to minimize dispersion of the sampled material. Sampling instruments were used to section a representative sample of material away from building component. Sealed, plastic packs were used to contain the sample and marked with the sample setial number. Sampling instruments were cleaned after collecting each sample to prevent cross contamination of subsequent samples. Inspectors utilized half-face respirators when appropriate, and gloves for adequate personal protection during sampling activities.
