how many common types of asbestos were available

There are six recognized types of asbestos, and among them three became the most commonly used in buildings and products over the 20th century.

How Many Common Types of Asbestos Were Available?

Quick Scoop

Historically, asbestos was mined in several mineral forms, but regulators and health agencies group them into six main types.

Out of these, three were widely used in commercial products and construction, so they are often referred to as the “common” types.

The Six Official Types of Asbestos

Experts and agencies such as the U.S. Environmental Protection Agency and international health bodies recognize six asbestiform minerals:

  1. Chrysotile (white asbestos) – serpentine group, curly fibers, historically used in most building products and automotive parts.
  1. Amosite (brown asbestos) – amphibole group, straight needle-like fibers, used in insulation, cement sheets, and ceiling tiles.
  1. Crocidolite (blue asbestos) – amphibole group, very thin, sharp fibers, used in some insulation and specialty products.
  1. Anthophyllite – less commonly used, sometimes present as a contaminant in other minerals (like talc or chrysotile).
  1. Tremolite – not widely used commercially on its own, but found as a contaminant in other materials such as vermiculite and some talc.
  1. Actinolite – rare in commercial products, more often present as a natural contaminant in other rocks and materials.

All six types are considered hazardous and capable of causing serious diseases such as asbestosis, lung cancer, and mesothelioma when inhaled over time.

The Three “Common” Types People Usually Mean

When people talk about “common types of asbestos,” they’re usually referring to the ones most widely used in construction and industry:

  • Chrysotile (white asbestos) –
    • Made up roughly 90–95% of asbestos used in buildings worldwide.
* Found in cement sheets, roofing, insulation, brake linings, gaskets, pipe lagging, and many other products.
  • Amosite (brown asbestos) –
    • The second most common type in many countries such as the U.S. and UK.
* Used in insulation boards, pipe insulation, roofing products, and fire protection materials.
  • Crocidolite (blue asbestos) –
    • Less used than chrysotile but still significant in certain industries.
* Appeared in high‑temperature insulation, some cement products, and specialty applications.

Because these three appeared so frequently in homes, schools, factories, and ships, guidance documents and survey reports often highlight them as the three main or common types of asbestos , even though six types are officially recognized.

Forum‑Style Takeaway and “Latest News” Angle

“So, how many common types of asbestos were available?”
In most practical and regulatory discussions, people talk about six types total , but focus heavily on the three common workhorse types (chrysotile, amosite, crocidolite) that dominated construction and industrial use in the 1900s.

Today, many countries have strict controls or near‑total bans on asbestos use, and current “latest news” stories around asbestos tend to focus on:

  • Ongoing removal and remediation of old asbestos in buildings.
  • Legal cases and compensation for asbestos‑related diseases.
  • Updates to workplace safety rules and guidance for tradespeople.

If you’re dealing with a specific building or product, modern advice is to assume any asbestos-containing material is dangerous , regardless of which of the six types it is, and to use licensed professionals for inspection or removal.

TL;DR:

  • There are 6 recognized types of asbestos in total.
  • Of those, 3 were the most common in real‑world use : chrysotile, amosite, and crocidolite.
