Giải thích
Standard hot-work practice, reflected in Cal/OSHA fire-prevention rules, is to relocate combustible and flammable materials at least about 35 feet from the work, and where they cannot be moved, protect them with fire-resistant guards, blankets, or curtains. Openings and cracks that could pass sparks to adjacent areas must also be covered. This keeps sparks and slag from finding fuel.
