Personal protective equipment is available and its use is ordered. (Use of protective gloves because
of sharp edges, ear protectors if necessary).

A sign, e.g. “in revision", is to be attached to the plant,
-
The safety devices may be removed,
-
The work to be carried out must not be done under time pressure,
