Asbestos was a common building material up until it was (partially) banned in 1978. Because of its lightweight thermal & acoustic properties, it was incorporated: insulation, floor and ceiling tiles, popcorn ceilings, the backing on vinyl sheet flooring & its adhesives, roofing shingles, siding, textured paint, & joint compound, soundproofing. The only way to know for sure if asbestos is present in your home is to have a CDPHE Certified Building Inspector create an asbestos inspection report. The inspector will collect various samples and send them off to a laboratory for Polarized Light Microscopy (PLM) analysis.
Asbestos poses a hazard when it is damaged/disturbed and its fibers are released into the air where they can get into your respiratory system.
Breathing asbestos fibers can cause a buildup of scar-like tissue in the lungs called asbestosis and result in loss of lung function that often progresses to disability and death. Asbestos also causes cancer of the lung and other diseases such as mesothelioma of the pleura which is a fatal malignant tumor of the membrane lining the cavity of the lung or stomach.

An estimated 75% of all vermiculite is contaminated with asbestos which was mined from the Libby Mine in Montana. As long as the vermiculite remains behind intact walls or in the attic space undisturbed and does not become airborne, it is does not pose a great threat. We would, however, recommend removing vermiculite in all instances due to the fact that unexpected water damage can cause ceilings to fall unexpectedly- resulting in a costly asbestos spill into the home which contaminates the contents of the home resulting in a costly insurance claim which not only includes the cost of the damage, but the cost of replacement for carpets, furniture, appliances, etc.
The abatement process is much easier and faster when the house is empty, resulting in a lower total cost for removal. This should be discussed during the home buying process.
After 1990, vermiculite was no longer contaminated with asbestos- if you placed vermiculite in your potting soil after 1990, there should be no reason to be concerned.
Current building materials do not pose much of a threat, but the removal and/or disruption of existing materials poses the greatest threat. Demolition of a preexisting wall to make way for new construction can potentially contaminate your entire home if the existing walls or materials contain asbestos. If your home was built prior to 1980, its advisable that testing be conducted before proceeding with remodeling or demolition
In 1991 the Fifth Circuit Court of Appeals vacated the 1989 EPA Toxic Substances Control ACT which banned most asbestos-containing products in the US. This means the original ban on the manufacture, importation, processing, and distribution was overturned.

An Asbestos Management Plan (AMP) is a site specific plan for a building or site that
details how the Asbestos risk at the site will be managed. It outlines specific roles and responsibilities, Asbestos management actions, and is used as a tool to reduce the risk of Asbestos spread and exposure to the lowest level reasonably practicable. Typical elements of an AMP are:
