Periodic checks

Periodic inspection checks of earthing systems in companies with at least one employee are regulated by Presidential Decree 462/01, a regulation also governed by Legislative Decree 81/08 which protects the safety of employees in the workplace.

The Employer is obliged to approve the electrical system and to commission a Body authorized by the Ministry of Economic Development to carry out a periodic check of the system every 5 years or 2 years (in the case of premises used as medical practices, places with greater risk of fire, or construction sites).
In the absence of employees, the obligation regulated by the CEI 64-8/7 standard to carry out checks to ensure the correct efficiency of protection devices remains.
