Objective This paper aims to show a practical case study of safety assessment concerning possible injuries and fire occurring in the engine room on-board a merchant ship, due to fatigue.
Methods The methodology was centred in literature hazard identification, measurements in real ships and heat stress indices definition.
Results Some corrections are proposed in order to obtain a safe environment for workers in the engine control room and to prevent fatigue risks at the engine room. This will allow adequate oil leakage detection and, as a consequence, improve fire prevention.
Discussion Training is a preventive control option, but this study allows the understanding of new corrective control options like design corrections.
