Summary:HIGHLIGHTS: Using unmanned aerial vehicles to inspect atmospheric discharge protection systems eliminates the risk of worked falling. By the inspection method is possible to prioritize the elements and sites needing maintenance. Maintenance activities at height can be planned through the use of Remotely Piloted Aircraft System. Brazil has the highest incidence of atmospheric discharges, on average of 77.8 million hitting the country yearly. Companies providing post-harvest services have a high monetary value concentrated in their predominantly metallic structures. Atmospheric discharge protection systems (ADPS) are used in this context to protect the facilities and people, composed of several elements that require visual inspection with a certain periodicity, an activity framed as working at height. This research aimed to establish a methodology for employing a Remotely Piloted Aircraf System (RPAS) in the visual analysis of the operational condition of external atmospheric discharge protection systems components located in grain storage structures to collect information during the preliminary risk analysis and planning of activities at height. A survey of the current literature related to the subject was carried out, in addition to the norms, inspection agencies, and operational prerequisites of this type of equipment in the national territory. Finally, a method was created and validated based on the inspection checklist with the main points for checking, which generates a score that represents the urgency level of intervention, applied in a unit located in western Parana, Brazil, on 11/28/2022. This procedure eliminated the risk of workers falling during the planning and inspection stage of the structures, which helped the qualified professional to issue the technical inspection report more quickly. The disadvantage is related to the dependence on favorable weather conditions. Key words: work at height, drone, unmanned aerial vehicles O Brasil e o pais com a maior incidencia de descargas atmosfericas, em media 77,8 milhoes atingem o pais todos os anos. As empresas prestadoras de servicos pos-colheita possuem um elevado valor monetario concentrado em suas estruturas, que predominantemente sao metalicas. Os sistemas de protecao contra descargas atmosfericas (SPDA) sao utilizados neste contexto para realizar a protecao das instalacoes e pessoas, os quais sao compostos por varios elementos que necessitam de inspecao visual com determinada periodicidade, atividade enquadrada como trabalho em altura. Esta pesquisa tem como objetivo estabelecer uma metodologia para o emprego de Remotely Piloted Aircraf System (RPAS) na analise visual das condicoes operacionais dos componentes de um sistema de protecao contra descargas atmosfericas externo, localizados em estruturas de armazenamento de graos para coletar informacoes durante a analise preliminar de riscos e planejamento das atividades em altura. Realizou-se um levantamento da atual literatura relacionada ao assunto, alem das normas, orgaos fiscalizadores e pre-requisitos operacionais deste tipo de equipamento em territorio nacional. Por fm, foi criado e validado um metodo com base no checklist de inspecao com os principais pontos para conferencia, que gera uma pontuacao que representa o nivel de urgencia de intervencao, aplicado em uma unidade localizada no oeste do Parana, Brasil, em 28/11/2022. Este procedimento eliminou o risco de queda do trabalhador na etapa de planejamento e inspecao das estruturas, o que auxiliou o profssional habilitado a emitir o laudo tecnico de vistoria com maior agilidade. A desvantagem relaciona-se a dependencia das condicoes climaticas favoraveis. Palavras-chave: trabalho em altura, drone, veiculos aereos nao tripulados
