O Gautica NR-10 é uma solução desenvolvida para apoiar a gestão da segurança em instalações e serviços com eletricidade, tornando as inspeções mais organizadas, padronizadas e eficientes. Com o aplicativo, é possível cadastrar projetos, criar inspeções de segurança e incluir diferentes tipos de equipamentos elétricos, como painéis, subestações, transformadores de energia e outros componentes presentes nas instalações. Durante as inspeções, os equipamentos podem ser avaliados e classificados de acordo com seus riscos, utilizando o método HRN. A ferramenta também permite selecionar recomendações de segurança alinhadas aos requisitos da NR-10, auxiliando na identificação de não conformidades e na definição das medidas necessárias para reduzir ou controlar os riscos identificados. Ao centralizar informações e padronizar as avaliações, o Gautica NR-10 facilita o acompanhamento das condições de segurança dos equipamentos e contribui para uma gestão mais preventiva, rastreável e consistente dos riscos elétricos.
