Giải thích
Asbestos-cement (transite) pipe releases hazardous asbestos fibers when dry-cut, ground, or broken. Under Title 8 §1529 (construction asbestos standard), such work requires controls like wetting to suppress dust, specific work practices, and often a registered asbestos contractor and trained workers. Inhaled asbestos causes lung disease and cancer decades later, so never dry-cut suspect cement pipe.
