Protection against arc faults should be considered in every company with electrical installations according to the circumstances. Necessary measures should be reviewed in a regularly recurring process.

In order to take the necessary measures, it makes sense to define protection goals. This way you check if the measures taken lead to the desired outcome.
Work on electrical installations may require different protection goals: e.g.

    Protecting employees during operation and maintenance
    against electric shocks and arc faults (e.g. external service employees)
    The reliability of the power supply to your systems with the maximum tolerable downtime
 

Summarise

• which work
• is performed by whom
• on which installations
• and how work is performed with which tools
   

The basis for your comprehensive protection concept can be the risk assessment as per german DGUV-I 203-077, international IEEE 1584 (2018) or american NFPA 70E (2021. In phases you determine how high the risk of a possible arc fault can be. The result influences the selection of your protection measures against arc faults and documents your decisions.

Invite your colleagues and talk about outcome of above mentioned topics. (goals, status quo, protections measures, risk analysis)
