(2) Upon the design and furnishing of new workplaces, the requirements of this Regulation shall be taken as a guide.


§ 2. General requirements

(1) The employer shall ensure that the risk factors present in the working environment do not endanger or damage the health of workers and that the work process does not cause physical or mental stress to workers.

(2) In the event of considerable physical or mental stress, working in a forced position for an extended period of time or monotonous work, the employer shall ensure that the working tempo is suitable and enable breaks to be included in the working time for workers.

(3) The employer shall implement measures in order to avoid a situation where a worker works alone for an extended period of time if this would involve a risk of accident or violence.
