The first steps of this lesson

Step 1: Two Tests: Asbestos Content and Surface Area

Before anything else, you decide whether a job is the kind that needs a certified, registered contractor. Cal/OSHA defines asbestos-containing construction material (ACCM) as any manufactured construction material with more than one tenth of 1 percent asbestos by weight (8 CCR 1529(r)(1)), and Business and Professions Code (B&P) 7058.5 sets the size line: asbestos-related work involving 100 square feet or more of surface area of asbestos containing materials. The Cal/OSHA Pocket Guide for Construction lists both tests for registration under section 341.6(a). The ordinary 1529(b) definition of ACM is still more than 1 percent, the same as federal 1926.1101(b); the 0.1 percent line is the California content test used for registration and consultants.

Step 2: Who Must Hold the Certification

B&P 7058.5 says a contractor shall not engage in asbestos-related work of 100 square feet or more unless it holds the C-22 Asbestos Abatement classification or the qualifier for the license passes the asbestos certification examination. CSLB Rule 833(c) says the ASB certification works together with the contractor's other classifications; a certified contractor may not take abatement work in a trade it is not licensed for unless it also holds C-22. No ASB exam is required for installing, maintaining or repairing asbestos cement pipe or sheets, vinyl asbestos floor materials, or asbestos bituminous or resinous materials (B&P 7058.5). New license applicants also complete the open-book asbestos booklet and submit it before the license issues (B&P 7058.5(b)).
