Employers are in the duty

According to DGUV Regulation 1 "Principles of Prevention", the employer(s) must ensure that the necessary help can be summoned immediately in the event of an emergency by means of signalling devices and organizational measures.

As this also applies to individual workplaces in particular, suitable measures must be taken. Among other things, this can be done by means of a personal emergency signaling system (PNA).
