Prohibition label - a tag with basic information about the work being carried out (date of commencement of work, completion date, responsible person, etc.)

If the equipment is configured or repaired by more than one person, but by a group of specialists, auxiliary tools of the blocking system can be used:

The blocking pad (hasp) allows several workers to carry out technical work, each of which blocks the working equipment with its own lock.
