They are real profs if can work in such a bad conditions! While working in Ad agency I saw the same situations with installers in my city.

This is rare in large firms, because they will have to pay сompensation when an accident occurs. But this is common among small firms (private entrepreneurs with simplified taxation) or brigades that work illegally, without official registration. They save on equipment, so often do without stairs, safety equipment, or welding equipment, preferring other ways of fastening. Do not blame them for frivolity, they just try to survive and feed their families.

btw, they don't look directly into the welding flashes. This is a trick: you just close your eyes and do your job to the touch:) Meet welders, level 80 :)))
