Lightning protection (SPDA)
Design and periodic inspection under ABNT NBR 5419.
Why it matters in Brazil
In Brazil the lightning protection system is called SPDA and is governed by ABNT NBR 5419. In the current edition of NBR 5419-3, the inspection interval depends on the risk of the structure: 1 year for structures with hazardous areas, explosive atmospheres, severe corrosion or essential services; 3 years for the others.
The SPDA report is often requested by the Fire Department (Corpo de Bombeiros) for the fire safety certificate, and by insurers.
Every engineering design, inspection or report in Brazil must be registered with an ART (Law 6.496/1977) by a professional registered with CREA (Law 5.194/1966). NR-10 also requires every organisation to keep the electrical design and records of earthing inspection and measurement (item 10.15.3).
What it covers
- air termination, down conductors and earthing;
- continuity of down conductors;
- equipment installed on the roof after the original design;
- surge protection (SPD).
What you receive
- design with risk analysis and calculation report, or inspection report with measurements and photos;
- action plan for non-conformities;
- ART registered with CREA.
Who signs
Dario Cini, electrical engineer and occupational safety engineer, graduated from the University of Caxias do Sul, with more than 10 years of work in the industry of Rio Grande do Sul.
