A C-22 Asbestos Abatement license (16 CCR §832.22, tied to Labor Code §6501.8) authorizes containment, encapsulation, or removal and disposal of asbestos-containing construction materials, with all work and documentation following DOSH’s own regulations. C-22 does not cover general hazardous-substance removal beyond asbestos specifically (B&P Code §7058.7) — a site with both asbestos and other contamination, like lead paint, may need C-22 plus a separate hazmat license. This course covers the CSLB-outline C-22 trade exam plus Law & Business: a full study guide, 4 practice exams, and an explanation for every answer. Read the full C-22 License Guide for the DOSH registration prerequisite and complete requirements.
