Sample Collection & Analysis

 

Excerpt from the Government of Alberta, Alberta Asbestos Abatement Manual, August 2019, Chapter 7.1.1:

As part of a hazardous materials assessment, sampling of materials suspected to contain asbestos are collected. Verification whether a material contains asbestos cannot be done conclusively by visual inspection alone; samples must be analyzed for asbestos content. Samples must be collected by a competent person and packaged/handled carefully to prevent asbestos contamination or exposure. Bulk sampling is considered a low-risk activity and the appropriate procedures need to be followed.

Some examples of the locations and types of products that contain asbestos include:

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:

FLEET Remediation Services Inc. does not recommend that a homeowner cut into their building materials to collect their own samples, as they could inadvertently disturb the materials, releasing asbestos fibers into your home.

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.
