8 Pre-Demolition Hazardous Building Materials Survey Residential and Commercial Property, 212 and 210 Street East, Peterborough, Ontario Project No.: May Asbestos Ontario Regulation 278/05 applies to buildings with regards to maintenance, renovations or demolition work where Asbestos-Containing Materials (ACMs) are or may be disturbed. The major requirements of the asbestos management program for the building owner include: Preparation and maintenance of a record of the location of asbestos-containing materials in the building; Notification of the building's tenants of the location of such material; Establishment of a training program for those employees of the owner who may work in close proximity to and disturb the material; Periodic inspection of the material to determine its condition; Remedial action on material that has deteriorated following the precautions and procedures prescribed by the regulation as Type 1, Type 2 and Type 3; and Removal of asbestos-containing materials to the extent practicable prior to demolition of a building or part thereof. The regulation prescribes work to be conducted according to three procedure types. The procedure to be followed depends on the type of material and the regulation provides instruction on how the work must be performed. Three regulations govern the control, handling, transport and disposal of asbestos in Ontario: Ontario Regulation 278/05, Asbestos on Construction Projects and in Buildings and Repair Operations, made under the Occupational Health and Safety Act (O. Reg. 278/05); Ontario Regulation 347 General-Waste Management (as amended) under the Environmental Protection Act; and The Regulations Respecting the Handling and Offering for Transport and Transporting of Dangerous Goods Lead Guideline: Lead on Construction Projects (issued by Ontario Ministry of Labour) has been prepared to raise the awareness of employers and workers to the hazards posed by lead in construction and the measures and procedures that should be taken to control those hazards.

The guideline classifies operations involving lead-containing materials into three groups, Type 1, Type 2 and Type 3 operations. The procedure to be followed depends on the anticipated airborne concentration of lead generated during the operation, which is dependent on the type of work performed. The guideline also provides instruction on how the work must be performed Silica Guideline: Silica on Construction Projects (issued by Ontario Ministry of Labour) has been prepared to raise the awareness of employers and workers to the hazards posed by silica in construction and the measures and procedures that should be taken to control those hazards. The document provides information on the following: Health effects associated with silica exposure; Methods for controlling the silica hazard; Classification of work; and, Measure and procedures for working with silica. The guideline classifies operations involving silica-containing materials into three groups, Type 1, Type 2 and Type 3 operations. The procedure to be followed depends on the anticipated airborne concentration of silica generated during the operation, which is dependent on the type of work performed. The guideline also provides instruction on how the work must be performed PCBs Ontario Regulation 362, Waste Management-PCBs, made under the Environmental Protection Act, controls the waste management and transfer of PCBs.

10 Pre-Demolition Hazardous Building Materials Survey Residential and Commercial Property, 212 and 210 Street East, Peterborough, Ontario Project No.: May METHODOLOGY 2.1 Survey Methodology The fieldwork was conducted by Mr. Fahim Hassan, Project Specialist and Mr. Ricardo Romero, Project Consultant, of OHE on May 6 and May 7, Identification of materials suspected of containing hazardous substances was performed by the surveyors who, through their knowledge (from published literature and past experience), were able to identify the potential presence of such materials in buildings. The fieldwork consisted of surveying all accessible areas in order to obtain an overall representation of the hazardous materials present. OHE followed the protocols outlined in O. Reg. 278/05 for collecting and analyzing bulk samples of materials suspected to contain asbestos. Visual assessment of the material was the primary method of identification with occasional physical contact for the purpose of collecting bulk samples or examining for underlying layers. Representative bulk samples were collected of materials suspected of containing asbestos. The tools used by the investigator to collect the bulk samples were cleaned after each sample was collected to avoid cross contamination. Samples were placed in plastic sealable containers, marked with a unique sample number and transported to an independent accredited laboratory for analysis. 2.2 Methodology for Bulk Sample Analysis Bulk samples of suspect ACMs were analyzed in accordance with a US EPA method for the determination of asbestos content in bulk materials, EPA Method 600/R-93/116. The EPA Method requires that the samples be analyzed using the Polarized Light Microscopy (PLM) technique. The percentage of asbestos in the sample is measured as perceived by the analyst in comparison to standard area projections and is greatly influenced by the analyst s experience. The method is useful for the qualitative identification of asbestos (type) and the semi-quantitative (% estimates) determination of asbestos content in bulk samples. The asbestos bulk samples were analyzed by EMSL Analytical, Inc. (EMSL), an independent and NVLAP accredited laboratory. 2.3 Methodology for Lead Analysis Testing for lead in paint was carried out using an X-ray Fluorescence (XRF) Spectrum Analyser. Painted surfaces contain concentrations of various elements which the XRF can detect using lowlevel radioactivity. The XRF unit is positioned against the exposed painted surface and the radiation from the XRF is directed at the painted surface. The radiation is absorbed by the painted Page 4

11 Pre-Demolition Hazardous Building Materials Survey Residential and Commercial Property, 212 and 210 Street East, Peterborough, Ontario Project No.: May 2014 surface and emits energy back to the analyzer as fluorescence. The level of fluorescence will be distinctive to a particular element present in the paint. Lead emissions are measured by the analyzer, and then converted into an electrical signal. The analyzer uses this electric signal to calculate and display the lead concentration in the paint surface. The low levels of radiation provide for accurate readings with the precision of 0.05 mg/cm 2 when measuring lead concentrations. The XRF is equipped with a depth index that indicates where the lead is located within the paint layers. The detection limit of the instrument varies with depth and ranges from mg/cm 2 to 0.05 mg/cm 2. The analyzer used by OHE performs an automatic self-calibration/quality control check when the unit is switched on. 3.

58 APPENDIX C BACKGROUND INFORMATION ON DESIGNATED SUBSTANCES

59 ASBESTOS Asbestos is a naturally occurring mineral. Asbestos is divided into two mineral groups: Serpentine and Amphibole. The division between the two types of asbestos is based upon the crystalline structure. The fibers of asbestos are long and thin, easily distinguishable when compared with non-asbestos minerals. The construction industry has been using asbestos for many years because of the ability of asbestos to withstand high temperatures as well as its strength and resistance to corrosive chemicals. When asbestos-containing material is disturbed dust is released into the air that contains asbestos fibers that have the potential to be inhaled into the lungs. Depending on the size of the individual fibers inhaled, some fibers can make their way deep into the air sacs (alveoli) of the lungs. Exposure to asbestos fibers may result in scarring of the lung tissue (asbestosis), cancer of the chest cavity (mesothelioma) or other asbestos related cancers. ACRYLONITRILE Acrylonitrile is explosive, flammable and toxic, found as a colorless or yellow clear liquid. It is used to produce a variety of products including plastics, adhesives, gaskets, seals and hoses. Health effects resulting in acute exposure to acrylonitrile vary from minor symptoms such as eye irritation, itching skin, blisters, headaches, sneezing and vomiting. Chronic exposure may cause cancers of the stomach, lymph system and brain. ARSENIC The common form of arsenic is grey in color with a metallic appearance. Arsenic has been used in the manufacturing of glass to eliminate the green color resulting from the impurities of iron compounds. It was also used in the productions of poisons. Arsenic is poisonous in doses significantly larger than 65 mg (1 grain), and poisoning can arise from a single large dose or from repeated small doses. BENZENE Benzene is an aromatic organic hydrocarbon existing either as a clear liquid or a vapour. Benzene is highly flammable and volatile material and was primarily a by-product in petroleum refineries. However, it has also been commonly used to produce styrene, synthetic rubbers, plastics, resins and solvents. Serious health effects can occur from exposure to benzene, mainly as a result of inhalation of vapours and mists. Ingestion by swallowing and absorption through the skin are also possible routes of exposure. Health effects can result from ingesting food or drink contaminated with benzene. Symptoms can range from irritated eyes, red blistering skin, headaches, nausea and drowsiness. Benzene exposure can also induce blood and bone marrow toxicity. Page 1

60 COKE OVEN EMISSIONS Coke oven emissions can be either in a condensed form as a brownish thick liquid, or uncondensed form as a vapour. Coke oven emissions are a mixture of coal tar, coal tar pitch, and creosote and contain chemicals such as benzo(a)pyrene, benzanthracene, chrysene, and phenanthrene. Chronic (long-term) exposure to coke oven emissions in humans results in conjunctivitis, severe dermatitis, and lesions of the respiratory and digestive systems. Epidemiologic studies of coke oven workers have reported an increase in cancer of the lung, trachea, bronchus, kidney, prostate, and other sites. ETHYLENE OXIDE Sources of ethylene oxide emissions into the air include uncontrolled emissions or venting with other gases in industrial settings. Other sources of ethylene oxide air emissions include automobile exhaust and its release from commodity-fumigated materials. Individuals may be exposed to ethylene oxide through breathing contaminated air or from smoking tobacco or being in the proximity to someone who is smoking. Ethylene Oxide has been linked to reproductive damage, including spontaneous abortions; cytogenetic damage; neurological effects ranging from nausea and dizziness to peripheral paralysis; and tissue irritation. ISOCYANATES Isocyanates are compounds that contain a group of atoms consisting of Nitrogen (N), Carbon (C), and Oxygen (O), which make isocyanates very useful in the manufacturing industry. Isocyanates are commonly used in the production of plastics, foams, and coatings. Health effects associated with exposure to isocyanates are: decreased lung function, cold and flu-like symptoms, fever and shortness of breath. Exposure to isocyanates can be through inhalation of vapour, mist or dust, or by direct contact. LEAD For thousands of years lead has been used industrially because of its poor conductive property. Lead has been commonly used for electric storage batteries, pigments, paints, and rubber compounds. Health effects associated with lead exposure can result in damage to the kidneys, gastrointestinal system, nervous system and reproductive system. Symptoms range from vomiting, and abdominal cramps to pains in joints and muscles. MERCURY At room temperature mercury is in the form of a silver colored liquid. Mercury can exist in three forms: elemental, the pure form; organic, where mercury is bonded to a carbon molecule; or inorganic, where mercury is bonded to a molecule other than carbon. Page 2

61 Mercury can be absorbed into the body by inhalation, ingestion or absorption through the skin. As a health hazard mercury can affect the respiratory system resulting in coughing and chest pains. Mercury poisoning can also cause kidney damage, skin irritation and may even harm the nervous system. SILICA Silica can be found naturally in two forms, crystalline or amorphous material. Crystalline silica is regulated due to its significant toxicity over the amorphous silica. The three most common forms of crystalline silica in the workplace are: quartz, cristobalite and tridymite. The physical properties of silica make it a valuable substance for use in a variety of different industries and processes such as an abrasive and scouring compound, fillers for paint and mastic and optical equipment.
