Ergonomic diagnosis on the operation of suspended scaffolds

Although work on scaffolds is usually associated with traumatic type injuries, the operation of that equipment can also lead to overexertion injuries.

In this context, an ergonomic diagnosis of the operation of two types of suspended scaffolds was conducted. They were referred to in this study as light scaffold and heavy scaffold – the difference lies in their dimensions and the number of gears. The assessment was based on five main criteria: workers´ perceptions; body posture assessment; measures of heart rate elevations; estimative of scaffolds´ speed; and the repetitiveness of movement in the operation of scaffolds´ levers. Even though workers have pointed out that they prefer the light scaffold, because it moves up to seven times faster than the heavy scaffold, the results indicated that the operation of both types is physically too demanding. Failures in the scaffolds´ design and the lack of attention directed towards ergonomics in regulations were regarded as relevant root causes for the poor working conditions detected in the types of scaffolds that were investigation. Embora o trabalho em andaimes suspensos seja normalmente associado a acidentes com lesões traumáticas, a operação desses equipamentos também pode ocasionar doenças ocupacionais causadas por esforço físico excessivo. Neste contexto, foi realizado um diagnóstico ergonômico da operação de andaimes suspensos mecânicos leves e pesados (as principais diferenças entre ambos se referem à quantidade de catracas e dimensões). O diagnóstico baseou-se em cinco critérios: percepções dos trabalhadores a respeito das condições de trabalho, avaliação da carga física postural, avaliação da carga fisiológica, estimativa da velocidade de movimentação dos andaimes e estimativa da repetitividade de movimentos na operação das catracas. Embora os trabalhadores tenham apontado preferência pelos andaimes leves, uma vez que estes podem ser movimentados até sete vezes mais rápido que os pesados, os resultados indicaram que a operação de ambos os tipos apresenta demanda física excessiva dos trabalhadores. Entre as causas dessa situação, podem ser destacadas falhas na concepção dos andaimes e a falta de consideração de requisitos ergonômicos nas exigências da NR-18.
