Hazardous Materials Survey of: Grandview Terrace Daycare – Flat Roof Sampling Date: 2017-01-05 Building Code: 6414 Address: 2075 Woodland Drive Surveyor: Patrick Li Work Notification Number: 10318140 Requested By: Jason Jotie Purpose: TARGETED HAZARDOUS MATERIAL SAMPLING Executive Summary
A City of Vancouver Hazardous Materials Technician has completed a Targeted Hazardous Material
Sampling Survey of the Roof at 2075 Woodland Drive – Grandview Terrace Daycare.
A targeted hazardous material sampling survey only identifies the hazardous building materials that
could be encountered or disturbed by in a specified area (Roof). Although this was a semi-destructive
survey, any hidden materials that were not addressed which may contain asbestos or lead should be
assumed to be hazardous until sampling demonstrates otherwise.

Scope of Work
A visual inspection of the roof areas at 2075 Woodland Drive – Grandview Terrace Daycare for the presence of building materials suspected to contain asbestos or lead. Surficial and Test Cut sampling were conducted.
An assessment of potentially hazardous materials, denoting their condition, potential for disturbance/damage, accessibility to workers or public, estimated quantity, if suspect asbestos containing, their friability, potential for fiber release and worker exposure was assessed.
Collection and analysis of material samples from the roof areas for the presence of suspect hazardous materials.
A risk assessment for the current condition of any damaged asbestos/lead containing materials determined to be present within the buildings including the priorities for removal/repairs.
Recommendations for the removal/repair of any damaged hazardous materials determined to require immediate action.
Asbestos-Containing Material: Methodology and Results Materials sampled were selected based on our experience and guidelines provided by WorkSafeBC (Safe Work Practices for Handling Asbestos). Building materials were assessed for potential asbestos content and nine (9) have been analyzed for asbestos by COV-approved labs. Asbestos-containing materials were NOT identified on the roof. Table 1: Materials Sampled and Analyzed for Asbestos Content AASL Lab Reference No. B01686 (12Jan2017)
Sample No. Location Material Result
6414-R01 South Roof Roofing Material Asbestos Fibres Not Detected
6414-R02 Middle Roof Roofing Material Asbestos Fibres Not Detected
6414-R03 North Roof Roofing Material Asbestos Fibres Not Detected
6414-R04 Deck Roof Roofing Material Asbestos Fibres Not Detected
6414-A01 Main Roof White Caulking Material on Metal Flashing Asbestos Fibres Not Detected
6414-A02 Deck Roof Grey Caulking Material on Skylights Asbestos Fibres Not Detected
6414-A03 Main Roof Black Caulking Material on Plumbing Stacks Asbestos Fibres Not Detected
6414-A04 Main Roof Silver Painted Transparent Caulking Material
on Vent Collars Asbestos Fibres Not Detected
6414-EXT01 Exterior Wall Cement Board Panels – Perimeter Walls Asbestos Fibres Not Detected
Lead-Based Paints and Coatings: Methodology and Results Total Lead in Paint Three (3) representative samples of paint were collected to test for the presence of lead. The sample was analyzed at a COV-approved lab for total lead. Information from the U.S. Occupational Safety and Health Administration (OSHA) suggests that the improper removal of lead paint containing 600 mg/kg lead results in airborne lead concentrations that exceed half of the exposure limit. Depending on the potential receptors and the work to be performed, paints with lead contents as low as 90 mg/kg can also result in dangerous airborne lead levels. A task-, and site-specific risk assessment must be conducted by City of Vancouver’s Hazardous Materials Team to determine if an Exposure Control Plan and safe work procedures are required (Lead-Containing Paints and Coatings: Preventing Exposure in the Construction Industry, WSBC 2011).

Two (2) paint samples exceeded the suggested exposure prevention limit of 600 mg/kg paint (Table 2). Leachable Results of Lead in Paint: No samples were analyzed for leachable lead. If required, lead-based paint should be tested for leachable lead prior to disposal to determine if they are hazardous waste as defined by BC Ministry of Environment.

Sample No. Location Description RESULTS (mg/kg)

6414ROOF-L02 Deck Roof Brown Paint on Metal Flashing 1170
6414ROOF-L03 North End Behind Flashing White Paint on Wood Trim 7850
OTHER HAZARDS AND NOTES: None observed If any of these hazardous materials are to be disturbed, contact City of Vancouver Hazardous Material Team for assistance with risk assessment, control and disposal procedures. RISK ASSESSMENT AND RECOMMENDATIONS Prior to renovation or demolition activities, the hazardous materials identified in this report must be safely contained before disturbance. Depending on the areas to be renovated or demolished, Additional destructive sampling may be required to identify asbestos-containing materials that were not accessed during this targeted hazardous material sampling survey. ASBESTOS Asbestos-containing materials were NOT identified in any samples taken from the roof during this targeted hazardous material sampling survey. LEAD PAINT Prior to cutting grinding, removing or otherwise disturbing lead-based paint, safe work procedures should be developed. The Brown Paint on Metal Flashing of the Deck Roof and the White Paint on the Wood Trim along the North End (Behind the flashing) are lead-based. All other paints should be presumed to be lead-based unless determined otherwise by testing.
