Exposure to Asbestos

Asbestos that was once widely used in various industries for its heat resistance and insulating properties has significantly decreased.

Old roof shingles may contain asbestos.

However, some products may still contain asbestos. Here are some examples of products that historically or potentially could contain asbestos:

  1. Building Materials:
    • Thermal insulation (pipe insulation, duct insulation, and loose-fill insulation)
    • Vermiculite insulation
    • Roofing materials (roof shingles, felts, and coatings)
    • Siding and cementitious boards
    • Ceiling tiles and acoustic panels
    • Flooring materials (vinyl floor tiles, linoleum, and floor adhesives)
    • Drywall joint compound
    • Fireproofing materials
  1. Automotive Parts:
    • Brake pads and linings
    • Clutch facings
    • Gaskets and seals
    • Heat shields
    • Hood liners
  2. Industrial Equipment:
    • Boilers and steam pipes
    • Thermal and electrical insulation
    • Electrical wiring insulation
    • Laboratory gloves and aprons
    • Fireproof clothing and blankets
  3. Consumer Products:
    • Hairdryers and other heat-resistant appliances
    • Fireplace gloves and stove gaskets
    • Potting soils and vermiculite products

It's important to note that the presence of asbestos in these products can vary depending on the manufacturer, production year, and region.

Asbestos-containing materials may present a health risk if they are damaged, deteriorated, or disturbed, releasing asbestos fibers into the air.
