The need for work procedures, engineering controls and personal protective equipment will need to be assessed on a project-by-project basis and must comply with provincial standards or guidelines. Performing an exposure assessment during work that disturbs lead in paints and coatings may be able to alleviate the use of some of the precautions specified by these standards or guidelines. Lead-painted items may be a hazardous waste. Test lead-painted materials for leachable lead prior to disposal Silica Construction disturbance of silica-containing products may result in excessive exposures to airborne silica, especially if performed indoors and dry. Cutting, grinding, drilling or demolition of materials containing silica should be completed only with proper respiratory protection and other worker safety precautions that comply with provincial standards or guidelines Mercury Construction disturbance of mercury in paint and coatings (or other materials) may result in overexposure to mercury. The need for work procedures, engineering controls and personal protective equipment will need to be assessed on a project-by-project basis and must comply with provincial standards or guidelines. Do not break lamps or separate liquid mercury from components. Recycle and reclaim mercury from thermostats when taken out of service. Liquid mercury is classified as a hazardous waste and must be disposed of in accordance with local regulations Pinchin LeBlanc Environmental Limited Page 11 of 13

35 APPENDIX II Methodology

36 Green Stem Housing Co-operative Pinchin File: Methodology Appendix II 1.0 GENERAL Pinchin conducts a room-by-room assessment (rooms, corridors, service areas, exterior, etc.) to identify the hazardous building materials as defined by the scope. Information regarding the approximate quantity, location, and condition of hazardous building materials encountered and visually estimated quantities are recorded. 1.1 Limitations on Scope The assessment excludes the following: Owner or occupant articles (e.g. stored items, furniture, appliances, etc.); Underground materials or equipment (e.g. vessels, drums, underground storage tanks, pipes, etc.); 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 includes limited demolition of wall and ceiling finishes (drywall or plaster) to view concealed conditions at representative areas as permitted by the current building use. Limited destructive testing of flooring is conducted where possible (under carpets or multiple layers of flooring). Demolition of masonry walls (chases, shafts etc.), structural items or exterior building finishes is not conducted. 1.2 Asbestos 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. 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 1 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 1 Environmental Protection Agency 2017 Pinchin LeBlanc Environmental Limited Page 1 of 3
