This research illustrates the steps in the process of improving safety signs, to reduce the risk of accidents in the rock blasting activity at Sociedade Mineira de Catoca, located in the province of Lunda Sul.This study was carried out from August to November 2019, where respondents were selected based on stratified random sampling.Of the 28 questionnaires applied, 18 were returned (by employees from the Occupational Safety areas -33.3%, Explosives Factory -22.3%, Environment -11.1% and Drilling -33.3%) and used to the study.Descriptive and triangulation analysis were used to determine the relationship between the variables.The results of the study demonstrate that the safety signaling suffers from improvements, as its state of conservation is reasonable and, consequently, shows unsafe conditions in the activities carried out in the different areas.Therefore, with the challenge of implementing the proposal under study, according to experts, the state of conservation of the signs would improve by 70%, providing a reduction in occupational accidents and an increase in productivity.
