Asbestos Testing

Sampling Procedure:

The samples are taken by the hand "grab" method, containerized, labeled and recorded on a chain of custody log, which will be submitted with the samples to L&S Consulting. The samples are analyzed by Polar Light Microscopy (PLM). The accredited test method is EPA/600/M-4-82/020. Procedures described in EPA/600/R-93/116 will be incorporated where applicable. Any sample with a positive PLM for asbestos, and under 10% content, are automatically "Point Tested". Testing is halted at the "First Positive" for any particular Homogeneous Area.

Certain items are assumed ACM for the following reasons. First, it may be impractical to obtain samples, such as roofing material. Secondly, if the material is considered Non- Friable. The matrix that may contain the ACM is considered sufficient to contain any asbestos material that may be present in a particular homogeneous area. These materials are Category 1 Non-Friable, like asphalt shingle roofing and floor tile. If any of these materials are in poor condition and would likely become friable during the demolition process, then they would be categorized as friable and be required to be removed prior to demolition.

Physical assessment factors:

Per AHERA requirements, the inspector will perform a physical assessment of all friable asbestos containing materials. This involves physically observing and documenting the current condition of each friable material, and assessing its potential for future disturbance (or fiber released potential). The inspector categorizes the materials current condition as good, fair or poor.

Hazard assessment factors:

Based upon the physical assessment, friable asbestos containing material are then given a Hazard rank. The hazards rank from seven (most hazardous), to one (least hazardous). The highest rank is reserved for materials that are significantly damaged or material that is so extensively damaged that it requires immediate corrective action. Hazard ranks 4-6 reflect materials which are "damaged" with the rank 6 indicating high potential for further damage and rank 5 indicating a moderate potential for damage. Hazard rank 4 denotes that a material has been damaged, however, the potential for any further damage is low. Hazard ranks 1-3 are reserved for materials currently in good condition with future disturbance potentials being high, moderate or or low (3,2, 1 respectively).

It is important to note that projects don’t always require full surveys of the property. For example, if you are planning on renovating your bathroom, we can simply sample the affected areas, i.e. flooring, ceiling and wall plaster, joint compound or textures of any kind. Just to be certain that it is safe for demolition!
