EXECUTIVE SUMMARY

Jacques Whitford Limited (Jacques Whitford) was commissioned by the Toronto Catholic District

School Board (TCDSB) to conduct an Asbestos-Containing Building Materials Assessment of St. Rose

of Lima Catholic School located at 3220 Lawrence Avenue East in Scarborough, Ontario.

The purpose of the assessment was to assist the TCDSB to meet the requirements of the new

asbestos regulation, Ontario Regulation 278/05 made under the Occupational Health and Safety Act

(OHSA), effective November 1, 2005. The assessment also includes the identification of asbestos-

containing materials (ACMs) that may require special attention.

The assessment was performed for the purposes of long term management of asbestos, and not for

construction or renovations purposes. Additional intrusive testing may be required prior to using this

information for construction or renovation.

The work was carried out in accordance with the requirements of the OHSA.

Based on visual assessment and laboratory analysis, asbestos-containing materials were identified to

be present at the subject facility. Table 1 below provides a summary of the materials identified and

recommendations on their management.

Table 1 – Summary of Findings and Recommendations

Issue Comments Recommendation

Asbestos Friable asbestos-containing materials were identified to be present in the form of pressed paper thermal pipe insulation. These materials were observed to be in good condition.

Non-friable asbestos-containing materials were identified to be present in the form of 9”x9” and 12”x12” vinyl floor tiles. These materials were observed to be in good condition.

Presumed asbestos-containing materials (PACMs) were identified to be present in the form of insulating cement on pipe fittings, vinyl sheet flooring, caulking materials, roofing materials, mastics and chalkboards. These materials were observed to be in good condition and were not sampled to preserve their integrity.

Prior to demolition or renovation work, undertake testing of presumed asbestos-containing materials to determine their asbestos content.

Asbestos-containing materials should be removed prior to the start of renovation work that may impact the material, in accordance with O. Reg. 278/05.

Should a material suspected to contain asbestos fibres become uncovered during demolition or renovation activities, all work in the areas that may disturb the material should be stopped. Samples of the suspect material should be submitted for laboratory analysis to determine if asbestos fibres are present. Confirmed asbestos materials should be handled in accordance with O. Reg. 278/05.

The statements made in this Executive Summary text are subject to the same limitations included in the

Closure Section 8.0, and are to be read in conjunction with the remainder of this report.

ASBESTOS-CONTAINING BUILDING MATERIALS ASSESSMENT

1.0 INTRODUCTION

Jacques Whitford Limited (Jacques Whitford) was commissioned by the Toronto Catholic District

School Board (TCDSB) to conduct an Asbestos-Containing Building Materials Assessment of St. Rose

of Lima Catholic School located at 3220 Lawrence Avenue East in Scarborough, Ontario.

The purpose of the assessment was to assist the TCDSB to meet the requirements of the new

asbestos regulation, Ontario Regulation 278/05 made under the Occupational Health and Safety Act

(OHSA), effective November 1, 2005. The assessment also includes the identification of asbestos-

containing materials (ACMs) that may require special attention.

The assessment was performed for the purposes of long term management of asbestos, and not for

construction or renovations purposes. Additional intrusive testing may be required prior to using this

information for construction or renovation.

The work was carried out in accordance with the requirements of the OHSA.

1.1 Assessment Objectives

The objective of the assessment was to:

� prepare an assessment report that identifies asbestos-containing materials present at the subject facility; and,

� provide recommendations for the management of these materials.

1.2 Scope of Work

The scope of work for this assessment involved the following:

� a “room-by-room” visual assessment of readily accessible room spaces of the subject facility for the presence of asbestos-containing building materials;

� an inventory of building materials/components that are suspected to contain asbestos;

� the collection of representative bulk samples from building materials suspected of containing asbestos fibres;

� laboratory analysis for the determination of the type and concentration of asbestos present in the samples submitted; and,

� preparation of a report documenting the results of the assessment, providing an interpretation of the laboratory analysis results and recommendations for the management of any asbestos containing materials.

2.0 DOCUMENT REVIEW

The SAP inventory provided by Toronto Catholic District School Board and documents on site, where

available, were reviewed by Jacques Whitford.

3.0 ASSESSMENT METHODOLOGY

A room-by-room visual assessment of the subject facility was made in order to check for the presence

of materials suspected of containing asbestos.

During the assessment, locations to collect discrete bulk asbestos samples of suspect building

materials were identified. Samples of representative materials were then collected at these locations in

accordance with the requirements of Ontario Regulation 278/05 made under the Occupational Health

and Safety Act.

An assessment of the condition, accessibility and exposure risk was completed for each occurrence of

an asbestos-containing material. The Public Works and Government Services Canada (PWGSC)

document entitled “Deputy Ministers Directive 057 – Asbestos Management” (Last Revised June 16th,

1999) was used as the basis for the criteria that was applied in evaluating the presence of asbestos-

containing materials at the subject areas, where applicable.

Samples of suspect ACMs from various building materials were collected and submitted to EMSL

Laboratories Inc. (EMSL) located in Westmont, New Jersey, for analysis using Polarized Light

Microscopy (PLM) with dispersion staining. The analysis was conducted following the U.S. EPA/600/R-

93/116 Methods. EMSL is certified under the National Voluntary Laboratory Accreditation Program

(NVLAP) to perform asbestos analysis of bulk samples.

The number of bulk samples was based on the requirements of the new asbestos regulation that

specifies the minimum number of samples of a particular building material that should be collected and

tested to consider a material non-asbestos-containing. A positive stop option was used during the

laboratory analysis of the building materials suspected to contain asbestos. Multiple samples of

visually similar material were collected and submitted for laboratory analysis.

The positive stop option involves testing a series of samples from a particular building material until test

results indicate the presence of asbestos. When this occurs, the remaining samples are not tested.

This is a cost effective method of limiting the number of samples that are ultimately tested.

Additionally, materials that had been previously sampled and identified to contain asbestos were

referenced from available reports and not re-tested.

A summary list of the bulk samples collected by Jacques Whitford, including a description of the

material, sampling location, type of analysis and laboratory test results is provided in Appendix 2.

4.0 ASSESSMENT LIMITATIONS

This report reflects the observations made within the subject facility only, and the results of analyses

performed on specific materials sampled during the assessment. Analytical results reflect the sampled

materials at the specific sampling locations.

Due to access restrictions imposed by working in occupied and operational spaces, the asbestos

content of some building materials could not be determined at some locations. Where applicable,

building materials that were not sampled but that may contain asbestos include, but are not limited to

the following:

� sub-grade materials;

� curtains;

� flooring material concealed beneath carpeting, ceramic tile, brickwork, hardwood flooring and/or concealed beneath existing sub-floors;

� drywall and/or wall plaster materials concealed behind new and/or additional walls;

� woven tape inside duct connection joints;

� inner ducting insulation;

� refractory brick;

� insulation material present inside walls (i.e. suspected asbestos-containing vermiculite insulation inside concrete block and/or brick walls);

� pipe straight-run and pipe elbow insulation within wall cavities, inaccessible ceiling spaces or crawlspaces;

� insulation materials inside fire doors;

� the mechanical inner linings of heating, ventilation and air conditioning (HVAC) units; and,

� heat protection materials inside mechanical installations and light fixtures.

If encountered during renovation or other activities, any suspected ACMs not identified within this report

should be presumed to contain asbestos and handled as such until otherwise shown to be non

asbestos-containing through analytical testing.

5.0 REGULATORY FRAMEWORK

Asbestos is included in the Designated Substances Regulations made under Ontario's OHSA. The

Designated Substance Regulation respecting Asbestos (R.R.O. 1990, Reg. 837, amended to O. Reg.

279/05) primarily regulates worker exposure to asbestos during manufacturing of asbestos containing

products, but also includes requirements related to respiratory equipment, measurement of airborne

fibres, and medical surveillance of exposed workers.

© 2008 PROJECT 1025760 March 7, 2008 4

The Ontario Regulation 278/05 made under the OHSA for Asbestos on Construction Projects and in

Buildings and Repair Operations, clearly defines asbestos-containing material as a material that

contains 0.5 per cent or more asbestos by dry weight. The new asbestos regulation (O. Reg. 278/05)

became effective as of November 1, 2005.

The General Waste Management Regulation (O. Reg. 347/90), under the Environmental Protection Act

(EPA) of Ontario, sets out the requirements for the proper disposal of asbestos waste in Ontario. The

waste must be placed in a double sealed container, properly labeled, free of cuts, tears or punctures

and disposed of at a licensed waste station which has been properly notified of the presence of

asbestos waste.

6.0 ASSESSMENT RESULTS AND DISCUSSION

The result of the assessment for asbestos-containing building materials is discussed below. The

evaluation criterion for assessing asbestos-containing materials is provided in Appendix 5. A list of

definitions for technical terms used in this report is provided in Appendix 6.

Asbestos-containing materials are grouped into two classifications, friable and non-friable materials.

Friable ACMs are those that can easily be crumbled or broken apart by mere hand pressure. When

these materials break apart asbestos fibres are then released into the atmosphere. Non-friable ACMs

or “manufactured products” are materials that by the nature of their manufacturing/construction do not

readily allow the release of asbestos fibres. These materials should not be cut or shaped with power

tools, since this procedure may allow for the release of the asbestos fibres.

O. Reg. 278/05 requires that an Asbestos Management Program (AMP) be implemented in buildings

that have been identified to contain friable and non-friable ACMs.

A summary list of the bulk samples that were collected during the assessment including a description of

the material, sampling location, type of analysis and laboratory test results is provided in Appendix 2.

A copy of the PLM laboratory Certificate of Analysis is provided in Appendix 4.

A summary of occurrences of asbestos-containing materials for areas that were inspected is provided

in Appendix 3. Each ACM occurrence includes the following information:

� room component that contains ACM;

� location of the ACM within the room space;

� ACM description;

� estimated quantity;

� original sample number or representative sample number;

� friability; and,

� condition.

© 2008 PROJECT 1025760 March 7, 2008 5

6.1 Friable Asbestos-Containing Materials

During the assessment, friable ACMs were identified by laboratory analysis to be present at the subject

facility in the form of:

� Pressed paper thermal pipe insulation.

Refer to Appendix 2 for the type and asbestos content; and Appendix 3 for specific location and

condition of these ACMs.

6.2 Non-Friable Asbestos-Containing Materials

During the assessment, non-friable ACMs were identified by laboratory analysis to be present at the

subject facility in the form of:

� 12”x12” vinyl floor tiles; and,

� 9”x9” vinyl floor tiles.

Refer to Appendix 2 for the type and asbestos content; and Appendix 3 for specific location and condition of these ACMs.

6.3 Presumed Asbestos-Containing Materials

Presumed asbestos-containing materials were observed to be present at the subject facility. The

following materials were identified but not sampled:

� Insulating cement on pipe fitting;

� Vinyl sheet flooring – yellow;

� Window and door caulking materials;

� Roof caulking materials;

� Roofing materials;

� Mastics; and,

� Chalkboards.

The insulating cement on pipe fitting observed in the Boiler Room Office was not accessible to sample

due to the presence of built-in racks. The vinyl sheet flooring observed within the YMCA Daycare Room

was inaccessible to sample due to ongoing daycare service. The other materials were not sampled

during the assessment to avoid damage. The materials were observed to be in good condition. As

these materials are known to have been manufactured with asbestos, they should be presumed to be

asbestos-containing unless proven otherwise by laboratory analysis.

6.4 Non-Asbestos-Containing Materials

Refer to Appendix 2 for a list of materials identified as non-asbestos containing through sampling and laboratory analysis.

7.0 RECOMMENDATIONS

Based on visual assessment and laboratory analysis, Jacques Whitford recommends the following with

regards to the ACMs and PACMs in the facility assessed:

� Prior to demolition or renovation work, undertake testing of presumed asbestos-containing materials to determine their asbestos content;

� Asbestos-containing materials should be removed prior to the start of renovation work that may impact the material, in accordance with O. Reg. 278/05; and,

� Should a material suspected to contain asbestos fibres become uncovered during demolition or renovation activities, all work in the areas that may disturb the material should be stopped. Samples of the suspect material should be submitted for laboratory analysis to determine if asbestos fibres are present. Confirmed asbestos materials should be handled in accordance with O. Reg. 278/05.

APPENDIX 5

Evaluation Criteria for Assessing Asbestos Containing Materials

© 2008 PROJECT 1025760 March 7, 2008 Appendix 5-1

Criteria for Assessing Asbestos Containing Materials

A description of the criteria used in evaluating the condition, accessibility and exposure risk of

asbestos-containing materials is provided below. The criteria is generally based on the Public Works

and Government Services Canada (PWGSC) document entitled “Deputy Ministers Directive 057 –

Asbestos Management” (Last Revised 1999/07/16) and industry standards of practice.

Assessment of Condition

Spray Applied Fireproofing, Insulation and Textured Finishes

In evaluating the condition of ACM spray applied as fireproofing, thermal insulation or texture,

decorative or acoustic finishes, the following criteria apply:

Good

Surface of material shows no significant signs of damage, deterioration or delamination. Up to one

percent visible damage to surface is allowed within range of GOOD. Evaluation of sprayed fireproofing

requires the Assessor to be familiar with the irregular surface texture typical of sprayed asbestos

products. GOOD condition includes unencapsulated or unpainted fireproofing or texture finishes,

where no delamination or damage is observed, and encapsulated fireproofing or texture finishes where

the encapsulation has been applied after the damage or fallout occurred.

Poor

Sprayed materials show signs of damage, delamination or deterioration. More than one percent

damage to surface of ACM spray.

In observation areas, where damage exists in isolated locations, both GOOD and POOR condition may

be reported. The extent or percentage of each condition will be recorded on the Assessor’s

reassessment form.

FAIR condition is not utilized or considered as a valid criterion in the evaluation of sprayed fireproofing,

sprayed insulation, or texture coat finishes.

The evaluation of ACM spray applied as fireproofing, non-mechanical thermal insulation, or texture,

decorative or acoustic finishes which are present above ceilings, may be limited by the number of

observations made, and by building components such as ducts or full height walls that obstruct the

above ceiling observations. Persons entering the ceiling area are advised to be watchful for ACM

DEBRIS prior to accessing or working above ceilings in areas of building with ACM, regardless of the

reported condition.

Other ACM

In evaluating the condition of mechanical insulation (on boilers, breaching, ductwork, piping, tanks,

equipment etc.) the following criteria are used:


Good

Insulation is completely covered in jacketing and exhibits no evidence of damage or deterioration. No

insulation is exposed. Includes conditions where the jacketing has minor surface damage (i.e., scuffs

or stains), but the jacketing is not penetrated.

Fair

Minor penetration damage to jacketed insulation (cuts, tears, nicks, deterioration or delamination) or

undamaged insulation that has never been jacketed. Insulation is exposed but not showing surface

disintegration. The extent of missing insulation ranges should be minor to none.

Poor

Original insulation jacket is missing, damaged, deteriorated or delaminated. Insulation is exposed and

significant areas have been dislodged. Damage cannot be readily repaired. The evaluation of

mechanical insulation may be limited by the number of observations made and building components

such as ducts or full height walls that obstruct observations. In these circumstances, it is not possible

to observe each foot of mechanical insulation from all angles.

Non-Friable and Potentially Friable Materials

Non-friable materials generally have little potential to release airborne fibres, even when damaged by

mechanical breakage. However, some non-friable materials, i.e., exterior asbestos cement products,

may have deteriorated so that the binder no longer effectively contains the asbestos fibres. In such

cases of significantly deteriorated non-friable material, the material will be treated as a friable product.

Evaluation of Accessibility

The accessibility of building materials known or suspected of being ACM is rated according to the

following criteria:

Access (A)

Areas of the building within reach of all building users. Includes areas such as gymnasiums,

workshops, and storage areas where activities of the building users may result in disturbance of ACM

not normally within reach from floor level.

Access (B)

Frequently entered maintenance areas within reach of maintenance staff, without the need for a ladder.

Includes: frequently entered pipe chases, tunnels and service areas or areas within reach from a fixed

ladder or catwalk, i.e., tops of equipment, mezzanines.

Access (C) Exposed

Areas of the building above 8'0" where use of a ladder is required to reach the ACM. Only refers to

ACM materials that are exposed to view, from the floor or ladder, without removing or opening other

building components such as ceiling tiles, or service access doors or hatches. Does not include

infrequently accessed service areas of the building.


Access (C) Concealed

Areas of the building which require the removal of a building component, including lay-in ceilings and

access panels into solid ceiling systems. Includes rarely entered crawl spaces, attic spaces, etc.

Observations are limited to the extent visible from the access points.

Access (D)

Areas of the building behind inaccessible solid ceiling systems, walls, or mechanical equipment, etc.

where demolition of the ceiling, wall or equipment, etc., is required to reach the ACM. Evaluation of the

condition and extent of ACM is limited or impossible, depending on the Assessor's ability to visually

examine the materials In Access D.
