ANALISIS FAKTOR RESIKO KESELAMATAN DAN KESEHATAN KERJA DI PLTGU CILEGON

Abstract

The operation of power plants has a high level of complexity and safety and health hazards to workers. Therefore it takes stamina condition of body healthy physically and spiritually. Based on baseline surveys the musculoskeletal disorders risk rate: 97% moderate and 3% high, the risk work-related stress level: 80% moderate and 3% high, the fatigue risk level: 83% high and 17% moderate.
