Electric cabinets are a major contributor to electrical fire hazards, with an occurrence of more than 10% of all fire events. This project addresses the comparison of various fire suppression approaches in engine control rooms, using Fire Dynamics Simulator as support tool. The project studies three different scenarios, one of them without a protection system, a second one with a clean agent as extinguishing tool and a final one, which implements an inherently safer design. For the first case, the gas temperature in the room reached a limit of 620 °C. This condition may cause structural damages to the room, as well as injuries to the personnel in charge of fire extinction. For the second scenario, it was determined that the extinguishing agent may decrease the negative effects of the fire, although it may not protect other important structures. Finally, the inherently safer design limits the negative effects to the cabinet where the fire occurs, protecting the structure of the remaining cubicles, as well as the personnel. |
