Back in my HAZMAT days, we did a lot of transfers from damaged containers to proper containers to mitigate the release of hazardous materials. When the HAZMAT was a flammable liquid, we oftentimes had to construct our own grounding grid. This was more than not a massive challenge for us as we did this all over North America and the soils differ immensely depending on where we were operating and the time of the year. But these guys have put together this awesome video showing a method that I never used, but probably should have on several occasions. Tank trucks travel along roadways and along the roadways are many other buried utilities – so hammering an 8′ long copper rod into the ground comes with its own hazards and problems. These guys show us how to use a horizontal grounding field which is less than 12″ deep when we have concerns of buried utilities. The video is the best I have seen and the explanations provided are EXCELLENT. But take notice of this…
