Recognize hot work and choose the applicable rules
Learning objective: Identify the job, jurisdiction, hazards and required workplace training before starting.
Welding, torch cutting, brazing and heating can start fires and expose people to burns, shock, fumes and radiation. Similar spark-producing work may also fall under the workplace hot-work program. A task does not become safe because it takes only a minute or uses no open flame.
General-industry welding and cutting requirements are in 1910.252 through 1910.254. Construction uses 1926.350 through 1926.354. The actual activity and applicable jurisdiction determine the rules; the company name or building address alone does not. Maritime work has separate standards and is outside this course's detailed coverage.
Look at the process, base metal, filler, coating, equipment, location and nearby work. Heat can pass through metal to ignite material on the far side. Sparks can reach lower floors, openings and distant material. Fumes and gases can affect helpers and people who are not welding.
This is an online safety knowledge course for general industry and construction. It does not qualify someone to make a code-compliant weld, operate unfamiliar equipment, enter a permit space or act as an authorized fire watch. The employer must provide actual equipment and task instruction and verify readiness before assignment.
