Instructions comprise, in particular, information with regard to appropriate behaviour and actions and have to be regarded as on-the-job training of employees.. (Example: workers must be informed about the proper use of personal ear protective devices if they have the obligation to wear ear protection at their workplaces). In contrast to information, instructions must be verifiably documented and should result in (proper) actions of employees. Instructions should be geared to the know-how and experience of personnel, and also constitute a vital measure in risk assessment at work (workplace evaluation).
