41 APPENDIX III Methodology

42 Asbestos Assessment Methodology April 19, 2017 Methodology Appendix Pinchin File: GENERAL Pinchin conducts a room-by-room survey (rooms, corridors, service areas, exterior, etc.) to identify the asbestos building materials defined by the scope of the work. All work is conducted in accordance with our own internal Standard Operating Procedures. Information regarding the location and condition of asbestos building materials encountered and visually estimated quantities are recorded. The locations of any samples collected are recorded on small-scale plans. As-built drawings and previous reports are referenced where provided. 1.1 Scope Limitations The assessment excludes the following: Articles belonging to the owner, tenant or occupant (e.g. stored items, furniture, appliances, etc.); Underground materials or equipment (e.g. vessels, drums, underground storage tanks, pipes, etc.); Building envelope, structural components, inaccessible or concealed materials or other items where sampling may cause consequential damage to the property. Energized systems (e.g. internal boiler components, elevators, mechanical or electrical components); Controlled products (e.g. stored chemicals, operational or process-related substances); and Materials not typically associated with construction (e.g. settled dust, spills, residual contamination from prior spills, etc.). The assessment is limited to non-intrusive testing. Concealed spaces such as those above solid ceilings and within shafts and pipe chases are accessed via existing access panels only Pinchin does not conduct demolition of walls, solid ceilings, structural items, interior finishes or exterior building finishes, to determine the presence of concealed materials. 1.2 Detailed Methodology Pinchin conducts an inspection for the presence of friable and non-friable asbestos-containing materials (ACM). A friable material is a material that when dry can be crumbled, pulverized or powdered by hand pressure Pinchin Ltd. Page 1 of 3

43 Asbestos Assessment Methodology April 19, 2017 Methodology Appendix Pinchin File: A separate set of samples is collected of each type of homogenous material suspected to contain asbestos. A homogenous material is defined by the US EPA as material that is uniform in texture and appearance, was installed at one time, and is unlikely to consist of more than one type or formulation of material. The homogeneous materials are determined by visual examination and available information on the phases of construction and prior renovations. Pinchin collects samples at a rate that is in compliance with Table 1 of O.Reg. 278/05. The sampling strategy is also based on known ban dates and phase out dates of the use of asbestos; sampling of certain building materials is not conducted after specific construction dates. In addition, to be conservative, several years past these dates are added to account for some uncertainty in the exact start/finish date of construction and associated usage of ACM. In some cases, manufactured products such as asbestos cement pipe are visually identified without sample confirmation. Drywall joint compound is sampled at exterior walls, columns or other locations that are unlikely to have been renovated in an attempt to determine the presence of asbestos in the original drywall compound. Delineation of asbestos-containing drywall compound from newer, non-asbestos drywall compound is not conducted. Flooring mastic or adhesive is sampled and analyzed if present on the underside of flooring samples (vinyl floor tile and vinyl sheet flooring). If present, the following materials are presumed to be asbestos-containing and are best sampled immediately prior to commencing renovation/disturbance: roofing, felts and tar concrete floor levelling compound elevator and lift brakes electrical components or wiring within control centers, breakers, motors or lights, insulation on wiring moulded plastic components (laboratory bench tops) refractory materials and insulations in boilers, incinerators and stacks insulation under metal clad boilers and vessels vermiculite in concrete block wall cavities adhesives and duct mastics caulking 2017 Pinchin Ltd.

The analysis is performed in accordance with Test Method EPA/600/R-93/116: Method for the Determination of Asbestos in Bulk Building Materials, July In Ontario an ACM is defined as materials containing 0.5% or more asbestos by weight. The asbestos analysis is completed using a stop positive approach. Only one result meeting the above regulated criteria is required to determine that a material is asbestos-containing, but all samples must be analyzed to conclusively determine that a material is non-asbestos. The laboratory stops analyzing samples from a homogeneous material once a result equal to or greater than the regulated criteria is detected in any of the samples of that material. All samples of a homogeneous material are analyzed if no asbestos is detected. In some cases, all samples are analyzed in the sample set regardless of result. Where building materials are described in the report as non-asbestos, this means that either no asbestos was detected by the analytical method utilized in any of the multiple samples or, if detected, it is below the lower limit of an asbestos-containing material in the applicable regulation. Asbestos materials are evaluated in order to make recommendations regarding remedial work. The priority for remedial action is based on several factors: Friability (friable or non-friable). Condition (good, fair, poor, debris). Accessibility (ranking from accessible to all building users to inaccessible). Visibility (whether the material is obscured by other building components). Efficiency of the work (for example, if damaged ACM is being removed in an area, it may be most practical to remove all ACM in the area even if it is in good condition).
