IntroductionAccidents and work-related diseases cost, in the world, at least 2,680 billion euros per year (Elsler et al., 2017) and it is estimated that 7,500 people die due to unsafe and unhealthy working conditions every day (International Labour Organization, 2019). To control and reduce this situation, occupational risk prevention activities are developed, which must be defined according to the context of each organization.These activities are necessary to create safe work environments and contribute to the protection of workers' health (Niu, 2010). This is highlighted by the actions arising from the Occupational Health and Safety Management System (OHSMS) registered in ISO 45001:2018, which aims to prevent injuries and health problems for workers by providing healthy and safe workplaces (International Organization for Standardization, 2018).The performance of this type of systems needs to be constantly evaluated, being necessary the use of indicators (metrics to quantify the processes performance), which allow the identification of weaknesses and potentialities, consequently assisting in decision making and definition of strategies to improve working conditions.
