Prior to renovating your home or other structure that could disturb asbestos containing materials in quantities greater than trigger levels an inspection must be performed to identify those asbestos containing materials. A licensed asbestos inspector can identify those materials that are suspect and discuss the general steps necessary ensure they are addressed by an appropriate method. The trigger levels are as follows:
- In single family residences material that is more than 32 square feet or more than 50 linear feet or will fill a 55 gallon drum will need to be abated using a certified asbestos abatement contractor.
- In other public and commercial buildings material greater than 160 square feet or more than 260 linear feet or will fill a 55 gallon drum will need to be abated using a certified asbestos abatement contractor.
In the state of Colorado, if material is disturbed that exceeds these trigger levels a permit is required. This permit takes 10 days to obtain, if using standard abatement techniques. The permit may require 60 days, if non-standard techniques are used. There are other methods for ensuring safety that do not include removal. Such methods include leaving it as is (if the material is not damaged and not likely to be disturbed), enclosing the asbestos material or encapsulating the material.
