Sample Collection & Analysis

 

As per the Alberta Asbestos Abatement Manual:

If an area within a building is being altered or renovated, materials that have the potential for releasing asbestos fibres in that area must be removed, enclosed or encapsulated. In buildings or parts of buildings that are being demolished, materials having the potential for releasing asbestos fibres must first be removed. These requirements are based on the potential for asbestos fibres to be released when the material is disturbed, not on the amount of asbestos in the material.

Building materials containing asbestos in a bound form are typically found in the following locations and products:

Building exteriors

  • asbestos cement siding panels – flat, corrugated, shingles or accent panels
  • asbestos cement soffits – flat or perforated panels
  • asbestos cement roof panels – corrugated
  • roofing felts and mastics
  • building overhangs – thermal spray
  • stucco
  • brick and block mortar
  • loose fill insulation in exterior wall cavities (vermiculite)

Flooring

  • vinyl asbestos tiles (VAT)
  • sheet vinyl flooring (asbestos paper backing)
  • floor leveling compound

Ceilings

  • t-bar ceiling tile
  • asbestos cement ceiling tile
  • acoustic and stippled finishes
  • plaster or drywall jointing materials

Walls

  • plaster or drywall jointing materials
  • stippled finishes
  • thermal spray
  • asbestos cement panels

Service areas

  • insulation in boiler rooms — boilers, vessels, pipes, ducts, incinerators, floors, ceilings, walls
  • fan rooms — insulation on pipes, ducts, chillers, floors, ceilings, walls
  • machine rooms — insulation on pipes, ducts, floors, ceilings, walls
  • crawl spaces — insulation on pipes, ducts
  • wall cavities, insulation above ceiling spaces — pipe and duct chases, pipes, ducts

Structural

  • fireproofing spray on beams, decks, joists, columns and other structural members

Pipes (insulation on either exposed or concealed pipes)

  • steam and hot water heating supply and return lines
  • domestic water supply and drain lines
  • chilled water lines
  • rain water and sanitary lines — asbestos cement or bell and spigot cast iron, insulated or bare pipe
  • gaskets in flanged pipe joints

Miscellaneous

  • incandescent light fixture backing
  • wire insulation
  • fume hoods – internal linings and exhaust ducts
  • lab counters
  • elevator brake shoes
  • heating cabinet panels (asbestos cement)
  • fire dampers and fire stop flaps
  • diffuser backplaster
  • emergency generators – thermal insulation and exhaust manifolds
  • firestopping
  • theatre curtains
  • welding blankets and screens
  • incinerators – internal insulation
  • cooling towers – panels and fill
  • duct tape
  • duct expansion/vibration isolation joints

Building products containing asbestos in an unbound or loosely bound form include:

  • insulating cements
  • sprayed insulation — fire resistant, acoustic, thermal, condensation control
  • insulation block — magnesia or calcium silicate
  • textiles — not saturated, for lagging, curtains or clothing
  • vermiculite insulation (may contain tremolite asbestos as a contaminant) – known by the brand name “Zonolite”

Please note:

We do not recommend that a homeowner cut into their building materials to take their own samples, as they could inadvertently disturb the materials, and therefore could cause asbestos fibers to become airborne into your home, creating a potential air quality concern.

FLEET Remediation Services Inc. personnel are available for consultation, and can advise our clients on the best course of action for testing and managing of asbestos-containing building materials.
