1.0 INTRODUCTION
DST Consulting Engineers Inc. (DST) was retained by Colliers International to conduct a Project-Specific Designated Substance Survey (DSS) at 5175 Victoria Avenue, Niagara Falls, Ontario, in support of the Proposed Niagara Probation and Parole Office Project (Colliers project number 1067862-271847).
2.0 SCOPE OF WORK
The survey implemented by DST included the 11 designated substances listed in Section 30 of the Occupational Health and Safety Act, R.S.O. 1990, Chapter 0.1. The investigation conducted was non-destructive, meaning openings into inaccessible wall/ceiling cavities were not created. Designated Substances, as identified under the Ontario Occupational Health and Safety Act, are as follows:
• Acrylonitrile,
• Arsenic,
• Asbestos (both friable and non-friable),
• Benzene,
• Coke Oven Emissions,
• Ethylene Oxide,
• Isocyanates,
• Lead,
• Mercury,
• Silica, and
• Vinyl Chloride.
3.0 METHODOLOGY
The field program for this survey was completed by DST on December 27th, 2018. The field program included a visual assessment of the project area and sampling.
![Page 6: ADDENDUM - Caird-Hall Construction Inc.€¦ · KAMCO 60 Grand Avenue North, Cambridge Ontario N1S 2K9 Technique Ltée Tel: 519 620-8684 Page 1 of 2 Project: Proposed Niagara Probation](https://reader030.vdocuments.us/reader030/viewer/2022040922/5e9bc72b1695902b5926185d/html5/thumbnails/6.jpg)

Materials suspected of containing designated substances were visually identified based on the surveyor's knowledge of the historical composition of building products. Materials suspected of containing designated substances were identified by appearance, age, and knowledge of historical applications. In Ontario, a material is defined as an asbestos containing material (ACM) if the material has a minimum asbestos content of 0.5 per cent (%) by dry weight, as per Ontario Regulation (O. Reg.) 278/05 Asbestos on Construction Projects and in Buildings and Repair Operations enabled under the Occupational Health and Safety Act (R.S.O. 1990, Chapter 0.1), as amended. ACMs can be divided into two categories: friable and non-friable material. A friable ACM is a material that can be crumbled, powdered, or pulverized by hand pressure and can readily release fibres when disturbed. Common applications of friable ACMs are sprayed or trowelled surfacing materials (e.g. sprayed fireproofing and textured coatings) as well as mechanical and thermal insulation. Non-friable materials are materials that will generally release fibres only when cut or shaped. Common non-friable ACMs include vinyl floor products, caulking applications, plaster, asbestos textile products and asbestos cement products (transite). Some of these products may become friable with time or when disturbed (e.g. plaster). Bulk samples of suspected ACMs were collected by DST during the site investigation. Samples were collected in order to meet the bulk sampling requirements stipulated in O.Reg. 278/05, as amended. The bulk samples were submitted to and analyzed by Paracel Laboratories Ltd. (Paracel). Paracel is certified under the National Institute of Science and Technology’s National Voluntary Laboratory Accreditation Program (NVLAP) to perform asbestos bulk sample analysis (NVLAP No. 200863-0). The bulk samples were analyzed using a combination of dispersion staining and polarised light microscopy (PLM). This analytical method complies with the United States Environmental Protection Agency (U.S. EPA) Method 600/R-93/116 dated July 1993, which is the regulatory approved protocol for bulk asbestos analysis in Ontario.
With regards to lead in paint, although the Ontario Ministry of Labour (MoL) has published a
guideline for control of lead exposures on construction projects in Ontario, it does not include
criteria for the classification of lead-paint. Instead, it uses presumed airborne lead concentrations
for specific tasks as criteria for classifying work. In Canada, the Federal Canada Consumer
Product Safety Act’s Surface Coating Materials Regulations SOR/2005-109 has lowered the
allowable concentration of lead in paints for new consumer products to 0.009% lead content by
weight (90 ppm). For the purposes of the survey and this report, paint applications having
detectable concentrations of lead are considered to be lead-containing.
Representative bulk samples of paints were collected by DST for lead content analysis. The
samples were analyzed at Paracel. The samples were analysed by Paracel using Inductively
Coupled Plasma – Optical Emission Spectrometry (ICP-OES) in accordance with MOE E3470,
ICP-OES.
Equipment that may contain PCBs (e.g., electrical transformers and equipment and fluorescent
light ballasts) can often be identified by examining manufacturer’s labels. For safety reasons,
DST personnel do not remove the ballast shields from fluorescent light fixtures to examine the

ballast codes unless the electrical circuit for the lighting or equipment had been tagged and locked
out by a qualified and licenced electrician.
Bulk asbestos and lead paint results are included in Appendix A.

Based on the analytical results of samples collected in Table 2, no lead was detected in the sampled paints.
4.3. Mercury
Approximately 184 Sylvania branded 21999 FO32/741/ECO T8 linear tubes containing mercury
were observed on site in light fixtures and stored in boxes in the main space.
4.4. Silica
Based on the historical composition of building materials, silica is assumed to be present in:
• Concrete and cement,
• Ceiling tiles,
• Drywall,
• Flooring compounds, and
• Mortars and grout.
4.5. Other Designated Substances
The following other Designated Substances were neither observed, nor suspected of being present, in forms or quantities that would impact planned work operations of the planned project:
• Acrylonitrile,
• Arsenic,
• Benzene,
• Coke Oven Emissions,
• Ethylene Oxide,
• Isocyanates, and
• Vinyl Chloride.
5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on observations made during the site investigation, the following Designated Substances are confirmed present in the planned project area may potentially be disturbed:
• Mercury,
• Silica.

DST’s recommendations for these materials, which are based upon both regulatory compliance and best practice guidelines, are included in the following sections below.
5.1. Mercury
There are no regulations that specifically govern the disturbance of mercury on construction
projects.
When removal of the fluorescent light tubes is required, the tubes should be removed intact from
the fixtures and appropriately stored. This prevents worker exposure to mercury vapour,
particularly if the tubes were energized shortly before removal. Similarly, other sources of liquid
mercury (thermostats, thermometers) should be removed intact and disposed of as per applicable
regulations
The Time Weighed Average Exposure Value (TWAEL) for mercury is prescribed by O. Reg.
490/09 Designated Substances, as amended. Work procedures and personal protective
equipment must be used to ensure that workers are not exposed to airborne mercury levels that
exceed this TWAEL.
Liquid mercury is classified as a hazardous waste under O. Reg. 347/90, as amended. The
transport of the waste to a disposal site is controlled by O. Reg. 347/90, the federal TDGA, and
the Ontario Dangerous Goods Transportation Act. It is now common practice to recycle
fluorescent light tubes, and other items containing mercury, recovering the component materials,
and avoiding the generation of hazardous waste.
5.2. Silica
The Occupational Health and Safety Branch of the Ontario Ministry of Labour have published Guideline: Silica on Construction Projects. This document classifies all silica disturbances as Type 1, Type 2 or Type 3 work, and assigns different levels of respiratory protection and work procedures for each classification.
The TWAEL for airborne silica is prescribed by O. Reg. 490/09 Designated Substances, as amended. Work procedures and personal protective equipment must be used to ensure that workers are not exposed to airborne silica levels that exceed this exposure limit. As a general rule, it is preferable to use more stringent dust suppression techniques and engineering controls as opposed to relying on respiratory protection to control worker exposure. Respiratory protection should only be relied on as a last resort when dust suppression techniques and engineering controls fail to control worker exposure to silica.
