Lightning protection inspection

Lightning protection systems play a vital role in protecting buildings, facilities and the people who live there. However, the effectiveness of these systems is only guaranteed if we ensure regular inspections and maintenance. In this article, we will explain in detail what a lightning protection inspection is, why it is important, and who is required to have one in Hungary.

What is a Lightning Protection Inspection?

A lightning protection inspection is a professional inspection process during which all elements of the lightning protection system are examined in detail to ensure that they comply with the relevant standards and regulations. This includes the lightning conductors, the grounding system, the bushings, and the connecting elements. The inspection reveals whether the system is able to effectively dissipate the energy of a lightning strike, thereby preventing the risk of fire, failure of electrical equipment, or even human life.

Why is a Lightning Protection Inspection Important?

Life Safety: Lightning strikes can cause serious accidents and life-threatening situations. Regular inspections ensure that the lightning protection system is always ready to deal with the danger.

Property Protection: Lightning strikes can pose a fire hazard, which can damage valuable objects, equipment and the building structure. Proper lightning protection reduces this risk.

Legal Obligation: In Hungary, the operation and regular inspection of the lightning protection system is mandatory for many buildings. Failure to do so may result in legal consequences.

Insurance Requirements: Insurers often stipulate regular inspections of the lightning protection system as a condition. Failure to do so may result in difficulties in settling insurance claims.

Who is Required to Have a Lightning Protection Inspection in Hungary?

Lightning protection inspection is mandatory for all buildings where a lightning protection system is in operation. According to the MSZ EN 62305 standard, lightning protection is mandatory for the following buildings, and regular inspections are also mandatory:

How to Prepare for a Lightning Protection Inspection?

Involve a Professional: The inspection should always be carried out by an expert, certified lightning protection specialist. Make sure that the chosen specialist has the necessary permits and experience.

Documentation Review: Gather lightning protection system plans, previous inspection reports, and other documentation.

Physical Review: The technician will review the physical condition of the lightning protection system, including conductors, grounding, and other components.

Repairs and Maintenance: If deficiencies are found during the review, they should be repaired immediately. Regular maintenance will help prevent future problems.
