Fire onboard ro-ro ferry usually claims a great number of casualties. In Indonesia 41% of major marine accidents were fire accidents. Victims of ferry fire accident are usually due to smoke, heat, and low visibility. The research is aimed to simulatethe flow of heat and smoke during a fire from car decks of the ferry to passenger decks and how the fire safety systemsprovide sufficient time for the passengers to escape from the affected areas. Fire Dynamic Simulator V5 (FDS V05) software was used in three different fire scenarios namely without sprinklers; with sprinklers but without smoke exhaust and fresh air supply fans; and with sprinklers, smoke exhaust and fresh air supply fans. It is proven that water sprinklers could suppress the distribution of heat, and smoke exhaust and fresh air supply fans have contribution in maintaining the visibility.

Roll on roll off passenger ferries play very important role in connecting Indonesia’s more than 17,000 islands. Since these ferries are categorized as ‘Non-convention’ vessels they are not mandatory to comply with international regulations, therefore they are very vulnerable to accidents including fire accident. The study was carried out to establish onboard fire safety assessment standards for Roll on roll off ferries operating on Indonesian waters to be used as guidance for authorities and operators to assess and to ensure the safety of the ferries. The assessment standards are focused on three accident sources include: the vessel; people on board; and the cargo. The standards are derived from fire hazards and their potential risk levels, which are categoriesed as intolerable; tolerable; and negligible. Refer to the risk levels obtained realistic and appropriate actions could then be implemented to prevent the ferries from fire accidents.

Positive Pressure Ventilation (PPV) is a firefighting tactic that can mitigate the spread of fire and the combustion products to improve the safety of firefighters and civilians in wind-driven high-rise fires than without PPV. The performance of a PPV tactic in wind-driven high-rise fires depends on various parameters that include wind speed, control of stairwell doors, number of fans, fan positions and placements, fire location etc. This paper describes the influence of these parameters on the efficacy of PPV operation that was studied by simulating wind-driven high-rise fire scenarios using computational fluid dynamics softwares Fluent 12.0 and NIST’s Fire dynamic simulator (FDS 5.0). The results obtained from Fluent and FDS found to be in close agreement with each other and have been used to optimize the PPV operation for better performance.

The technical parameters adjustment of smoke control system in a complicated underground commercial zone is studied by numerical simulations. An underground fire model (it encloses a hotel, a supermarket, and a net bar) and five typical fire scenarios are designed. The Fire Dynamic Simulator code is used to investigate the characteristics of fire spread and smoke movement, and obtain the available safety egress times in different fire scenarios. The required safety egress time is calculated based on the data of actual simulation exercises and numerical simulation by Building EXODUS. The simulation results show that, when the smoke exhaust rate is 5.56 cubic meter per second and air low rate reaches 3.89 cubic meter per second simultaneously, the available safety egress time is more than the required safety egress time.

Steel car parks exhibit high vulnerability to fire, as a consequence of the degradation of the steel mechanical properties at high temperatures and of the combustible type and amount. Real fire accidents in open car parks demonstrated a much faster and extended fire spread than predictions, assuming that a fire spread rate of 12 min and consider at most 3-4 vehicles on fire at the same time. Fire Dynamic Simulator (FDS) is applied in this current paper to study fire spread between cars. The outcomes of the investigations show that the fire spread is strongly influenced by the geometrical layout and that the distance between cars plays a determinant role on the fire spread rate and ignition of adjacent cars. In particular it was found that the fire spread can be faster than 12 minutes in the case of the cars parked 40 and 60 cm from each other.

Rational spatial distribution plays a significant role on fire safety of subway station. The location of ticket machine is one of the main factors affecting fire feature of such stations. Taking a certain subway station as a physical model, this paper carries out simulation analysis on several fire scenarios with the help of software FDS. By comparing the fire temperature, smoke density as well as visibility under different kinds of space between ticket machine and the escape exit, the appropriate space between ticket machine and escape exit is obtained which could be a reference for practical projects

Subway station fire can easily cause many calamities that lead to a large amount of social and public problems, because the smoke spread moves in the same direction as the personnel evacuation. Therefore, life safety issues caused by the subway station fire and relevant investigation should be comprehensively taken into account in the fire safety design in order to minimize the fire accident loss. Here previously reported fire accidents in the subway station are reviewed in detail and some research on the life safety of the subway station fire are presented, which could be helpful for the accident prevention and provide guidance to future study on the safety design in the subway station fire.

Goods and shelves are closely and numerously put in the logistics center, so there are many hidden dangers. People’s life safety and property safety are threatened by fire. The key of putting out fire and evacuating people is to grasp the changes of the important parameters in the fire. In this paper the FDS (Fire Dynamic Simulator) software developed by the U. S. National Institute of Standards and Technology (NIST) is used to build a fire model and sets two fire scenarios to analyze the fire spreading process in logistics center. According to the numerical simulation results, reasonable suggestions are put forward in the end.

Positive Pressure Ventilation (PPV) is a widely used fire fighting tactic in which a fan is used to push hot products of fire out of a burning structure. There is a recent body of research that has been conducted regarding the advantages and disadvantages of PPV. Studies of PPV most commonly use full scale experimental fires and/or computational simulations to evaluate its effectiveness. This paper presents computational simulations that have been conducted using Fire Dynamic Simulator (FDS) version 5 to evaluate the effects of exit vent location on resulting fire room conditions during the application of PPV to a ventilation constrained fire. The simulations use a simple one room structure with an adjacent hallway. We are simulating this geometry because we are in the process of designing and constructing a similar experimental compartment. Cold flow simulations are first conducted to understand how much the presence of the fire heat release affects the flow patterns. Then, two simulations which employ PPV with different exit vent locations are compared. The differences between the two simulations are detailed and a physical explanation for the differences is presented.
