The aim of BREND 2 is to improve the possibilities for a safe firefighting operation in ro-ro spaces by improving the competence in how personnel assess the fire risks with alternative fuel vehicles. Special focus will be on the risks associated with fire in gas driven vehicles and the risks of being exposed to toxic substances during firefighting.
The conclusion of a previous research project (BREND 1) was that the greatest risk of damage to life, health and the environment arises from fire in gas-driven vehicles. Tanks from gas-driven vehicles can cause a jet flame in case of fire, but they can also explode if the safety-fuse does not work properly. In order to get a better idea of the risks of gas-driven vehicles exposed to fire, fire tests will be carried out. These fire tests will examine how different types of safety-fuses work and how different extinguishing methods affect the safety of firefighting operations in ro-ro spaces.
For electric vehicles, one of the conclusions of BREND 1 was to avoid the fire gases as far as possible due to the uncertainty about how toxic these are. This conclusion may lead to a delay in firefighting operations, which may have major consequences for the ship and its passengers and crew. In order to improve the risk assessment in manual firefighting operations and to reduce the risk of exposure to harmful fire smoke, data from fires in battery vehicles will be used to simulate the conditions in a ro-ro space and the risk of exposure to toxic substances will be analyzed.
The project will be ongoing in 2021 and the results are expected to make recommendations on risk assessment in the case of manual firefighting operations in the event of a fire in ro-ro spaces. The recommendations may include special protective measures in case of gas tanks exposed to fire or possibilities to reduce exposure to toxic gases, such as ventilation needs, the use of a chemical suit or other equipment and tactics.
