Fire-smoke control strategies in road tunnels: The effectiveness of solid barriersTunnelsSmokeSolid barriersVisibilityThis paper discusses the effect of introducing solid barriers at the ceiling of a tunnel on slowing down propagation of smoke resulted from a fire using numerical simulations. Significant ...
Experiences on the specification of algorithms for fire and smoke control in road tunnels The main objective of ventilation systems in case of fire is the reduction of the possible consequences by achieving the best possible conditions for the evacuation of the users and the intervention of the eme...
The philosophy of fire ventilation in road tunnels has been improved in the past years. The goal of fire ventilation for smoke control is the handling of t... P. Pospíil,R. Brandt 被引量: 0发表: 2004年 VEHICLE TUNNEL RISK REDUCTION BY ACTIVE FIRE SUPPRESSION AND SMOKE CONTROL The paper...
The fire which started at a 121-hectare dump site in Hteinpin Cemetery had burned for several days before it was initially under control on April 29, causing health hazards in nearby townships due to the smoke and carbon monoxide emitted from the fire. A total of 40 patients were hospitaliz...
aIn the subway tunnel, set the fire and smoke partition, when the fire broke out, fire control in a certain range, to stop the fire's rapid expansion. Practice has proved that long-term as a fire partition and set the fire curtain, there are many hidden dangers in the practical use, ...
In the August issue, the author discussed the movement of smoke in buildings. In this, a companion article, he examines an approach to controlling the movement of smoke to permit safe evacuation of a building and to lessen its hampering effect on fire fighting operations.This...
Investigation Of Fire-Induced Smoke Movement In Tunnels And Stations: An Application To The Paris Metro The behavior of fire-induced smoke layers in a tunnel and a particular station of the Paris Metro, in the presence of ventilating-air flow, is experimental......
The 1/15 reduced-scale experimental tests using Froude scaling have been carried out to investigate the smoke diffusion characteristics in tunnel fires with the natural ventilation mode. The propane gas fires with heat release rate of 6.08 and 11.48KW corresponding to 5.3 and 10MW in full-scale ...
According to the simulation results, ventilation and smoke control is used in the cases of fire on the second and third floor in the underground, the airflow speed of the stairway reached 2 m/s, which can completely restrain the smoke on the fire floor. According to the characteristics of ...
Road tunnels in Norway are becoming increasingly complex, and several long subsea tunnels are either under construction or planned for the near future. The Office of the Auditor General in Norway recently stated that there is a need to improve fire safety in road tunnels. By systematically examini...
