When is asbestos the most dangerous? What types?

Asbestos on its own is normally harmless when left untouched. It isn’t typically until the asbestos containing material is damaged, disturbed, or removed that it becomes a potential health and safety issue.


Depending on the type of asbestos you’re dealing with, the process for handling it will most likely be a little different.

The 2 Types of Asbestos Products

Bonded asbestos materials comprised of asbestos fiber and a cement base have been used for a variety of home construction applications including insulating boards, circuit boards, electrical panels, ceiling tiles, wall linings, and partitions. Asbestos fiber isn’t usually released from these building materials until it is cut or damaged.

Loosely bound asbestos, unlike the bonded variety, is not typically used in residential structures to insulate; rather in commercial buildings to fire and sound proof them. While fiberglass has mostly replaced loose fill asbestos based insulation, some private residences still do have some loose bound asbestos insulation around heaters, stoves, hot water systems, and pipes. Loose fill asbestos insulation can also still be occasionally found in residential attics as well as underneath vinyl and linoleum floor coverings.

While bonded asbestos products are rigid and are rather easy to dispose of (while general personal protective is in use), loosely bound asbestos products are highly dangerous and can free asbestos fiber into the air with only slight agitation.  It should only be handled with an extensive containment policy being followed.
