Why is it required that video recording be done for special-grade hot work? How long should video recordings be kept? Is video recording also required for upgraded Class 1 hot work that becomes Class 0 hot work?
Personally, I think it’s a regulatory measure； Save for 1 month ； We have to record video whenever we perform hot work at this level
For level-A hot work, video recording is required; video capture is necessary
The new requirements introduced in GB30871-2022
