Training Classes
Our instructors are renowned for their knowledge, personality, and genuine interest in their students. Whether teaching an open enrollment class at our facility or a custom class on-site at your facility, they make a lasting impression. We continually receive feedback praising our instructors and our training content excellence as the primary reasons students prefer Terracon.

Asbestos Classes
We offer both INITIAL and some REFRESHER classes IN-PERSON. All our REFRESHERS are available as ONLINE classes. Click on our Registration link below for details. For Asbestos Worker and Supervisor applications in Washington, notarization is required to be provided by the training provider. Our online worker and supervisor refreshers now INCLUDE CONVENIENT ONLINE NOTARIZATION of student application forms! You also have the option of coming into our Mountlake Terrace location in-person for your notarization.

8-Hour Class II Intact Asbestos Training (Asbestos Cement Pipe, Roofing, Flooring, etc.)
Did you know that sometimes Certified Asbestos Workers are not required for abatement work? If your project has "miscellaneous" asbestos-containing materials (ACM) that will remain non-friable (intact) during removal, your workers may only need 8-hour Class II Intact ACM training. We can provide the 8-hour training required and specific to the type of ACM on your project. The OSHA & WA L&I regulations require this training be specific to one type of intact ACM and include hands-on. Our training is conducted in-person at your location, or ours if more convenient for you. In Washington State, L&I accreditation is required for asbestos cement pipe training, and we are accredited! Contact us if you would like to explore training options that will fit your needs.

2024 EPA Chrysotile Asbestos Ban
In March of 2024, EPA finalized the ban on Chrysotile prohibiting ongoing uses of this mineral, which is the only known form of asbestos currently used in or imported to the United States. Raw chrysotile asbestos was imported into the United States as recently as 2022 for use by the chlor-alkali industry. Most consumer products that historically contained chrysotile asbestos have been discontinued. Click below for the full EPA press-release.

Vermiculite And Asbestos In WA
Vermiculite in building materials can be naturally cross-contaminated with asbestos. For that reason special care is needed to minimize dust during handling and disposal. Most landfills require you dispose of it as asbestos-containing material, even if it is not. Some WA local clean air agencies regulate vermiculite as asbestos-containing material too. Click the link below for a WA map and links to all the local clean air agencies to find their asbestos regulations.
