A 59-year-old woman died on Sunday morning (26) after suffering an electric shock while cleaning solar panels installed on the roof of a building in the municipality of Panelas (PE). The victim was using a stainless steel rod during cleaning when she accidentally touched a medium voltage wiring.
Rescue teams were called and the entire The area was isolated by the Military Police, who awaited the presence of the IC (Criminalistics Institute) and the PCPE (Civil Police of Pernambuco). After the examination, the body was sent to the IML (Institute of Legal Medicine) and a a police investigation was opened to investigate all the facts.
Neoenergia technicians also visited the site and confirmed that the distribution network met the standards established by national electricity sector regulations. “The distributor reinforces the importance of maintaining a minimum distance of 2,5 meters from electrical wiring,” the concessionaire informed in a note sent to the press.
Safety and prevention
In an interview with Canal Solar, Laís Andrade, engineer at CS Consulting, highlighted the importance of never carrying out preventive maintenance or cleaning on photovoltaic systems without the proper technical preparation.
According to her, the ideal is to hire specialized companies, which have qualified professionals, adequate equipment and standardized safety procedures for this type of service.
Laís emphasized that the consumer also plays a fundamental role in this process and must demand proof of certifications and training from professionals hired to work with electrical installations.
Laís also pointed out that the use of appropriate equipment can significantly reduce the risk of electric shocks, especially when cleaning modules installed near the medium voltage grid.
"Ideally, the cables used to extend cleaning equipment should be insulated or coated with non-conductive materials, such as rubber or resistant polymers. This reduces the risk of accidental contact with energized surfaces or electrical wires," the engineer added.
The standards cited by Laís deal with specific workplace safety requirements:
- NR 10 – establishes control measures and preventive systems to ensure safety in electrical installations and services;
- NR 18 – defines working conditions and protective measures in the construction industry;
- NR 35 – determines the minimum requirements for carrying out activities at height, including the appropriate use of PPE (personal protective equipment) and specific training.
