To become a properly trained and accredited asbestos professional you will need to seek training from a training provider that offers courses approved by the EPA or a state to conduct asbestos training pursuant to the Asbestos Model Accreditation Plan. Most states also require a license to perform this work. Your training course completion certificate is a general prerequisite to applying for such a license. The training courses vary in length from 2 to 5 days depending upon the type of work you wish to perform. Accredited asbestos training courses are offered in five separate disciplines; Asbestos Abatement Worker, Asbestos Abatement Supervisor, Inspector, Management Planner and Project Designer. Some states may refer to these training disciplines by different, yet similar names.
