Another necessary function in the pipeline construction is welding. The OSHA standard governing hot work, or welding, is 29 CFR 1910.252. The standard sets common-sense requirements to prevent explosions or physical harm to workers such as burns.
Potential Hazard:
- Getting burned by fires or explosions during hot work.
The basic precautions for fire prevention are:
- Perform hot work in a safe location or with fire hazards removed or covered. [1910.252(a)(1)(i)]
- Use guards to confine the heat, sparks, and slag and to protect the immovable fire hazards. [1910.252(a)(1)(ii)]
- Do not perform hot work where flammable vapors or combustible materials exist. Work and equipment should be relocated outside of hazardous areas when possible. [1910.252(a)(1)(ii)]
- Make suitable fire-extinguishing equipment immediately available. Such equipment may consist of pails of water, buckets of sand, hoses, or portable extinguishers. [1910.252(a)(2)(ii)]
- Assign additional personnel (fire watch) to guard against fire while hot work is being performed in locations where anything greater than a minor fire might develop [1910.252(a)(2)(iii)(A)] or if any of the following conditions exist:
- Appreciable combustible material is closer than 35 feet to the point of operation.
- Appreciable combustibles are more than 35 feet away but are easily ignited by sparks.
- Wall or floor openings within a 35-foot radius expose combustible material in adjacent areas, including concealed spaces in walls or floors.
- Combustible materials that are adjacent to the opposite sides of metal partitions, walls, ceilings, or roofs and that are likely to be ignited by conduction or radiation.
- Appreciable combustible material is closer than 35 feet to the point of operation.
- Fire watchers shall:
- Have fire-extinguishing equipment readily available and be trained in its use.
- Be familiar with facilities for sounding an alarm in the event of a fire.
- Watch for fires in all exposed areas, try to extinguish them only when obviously within the capacity of the equipment available, or otherwise sound the alarm.
- Maintain the fire watch at least half an hour after the completion of welding or cutting operations to detect and extinguish possible smoldering fires. [1910.252(a)(2)(iii)(B)]
- Have fire-extinguishing equipment readily available and be trained in its use.
