Welding will be handled below:

Welding Operations shall be prohibited with the exception of welding operations conducted under the following guidelines:

1. A 30’ area clear of any combustible materials where welding, cutting or grinding operations are being performed;

2. A 30’ area clear of any combustible materials is required with an enclosure that is covered;

3. Anything elevated above 20’ - the radius will increase by two feet for every elevated foot;

4. Surface around area will be wetted down;

5. Wind Speed must be less than 15 mph (maximum);

6. Relative humidity must be above 30 percent;

7. One fire guard watching with pressurized extinguishers on site for every person welding, cutting, or grinding;

8. Each site will have cellular telephone communications for emergency response;

9. All welding, cutting and grinding operations may be performed in a total welding enclosure, or “welding box,” that is sufficiently high enough to control sparks and includes a fire retardant cover over the top. Wind speeds must not exceed 30 mph while utilizing an enclosure; Where welding (above ground and sub-surface) is required in an area where there is potential for a hazardous atmosphere, barriers will be substituted for total enclosures (e.g. “wind walls”) to prevent sparks from coming in contact with any combustible material. The barriers will be installed to allow ventilation of the work area and ingress and egress to the work area for personnel safety. Sub-surface, or “bell hole” welding and grinding operations within approved excavations are allowed if all other mitigation efforts are included.
