Arc flash and ATPV
How dangerous each panel is, and which clothing is really needed.
Why it matters in Brazil
NR-10 requires protective clothing to be suited to the arc flash risk. The protection value (ATPV) is not chosen from a catalogue: it depends on the incident energy at each panel, calculated under ABNT NBR 17227 and IEEE 1584.
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
- incident energy at each work point;
- arc flash boundary;
- measures to reduce the risk, before clothing.
What you receive
- study with calculation report;
- panel labels;
- mitigation plan;
- 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.
Professional registration: CREA-RS 211.450 (public check on the CREA-RS website).
Company: Cini Engenharia, CNPJ 25.268.313/0001-56 (check with the Brazilian Federal Revenue).
Every job is delivered with an ART, the registration of technical responsibility at CREA required by Law 6.496/1977: the name of the engineer in charge stays tied to the document.
