Abstract
Smoke occurs as a result of solid and liquid particles carried in the air from the burning of materials created from the combustion of gases. A dark colored smoke screen is formed. It may be toxic and explosive which make evacuation and responding to the fire more difficult. All these problems can be overcome with an appropriate smoke evacuation system. Smoke evacuation systems can be divided into two categories as natural and mechanical systems. However, they can vary according to needs, the people intensity; materials found in the structure and area, architectural features and design standards. The modelling based on the scenario planned for the most appropriate smoke evacuation system was carried out in compliance with international standards and local regulations. In this study, a vehicle part warehouse belonging to the Oyak Renault automobile factory was established inexactly the same way as the original. Using the CDF based PHONEICS system it was designed that a fire broke out in the warehouse and in the design, parking lot fire data were taken into consideration as given in British Standard (BS) standards ‘Components for smoke and heat control systems’ section 7. Vehicle parts found in the warehouse were in parallel with vehicles which had installation completed in the parking lot without a sprinkler. The smoke emerging as a result of the fire, which had an area of 5×5 m2 and 8MW magnitude and broke out in the warehouse (without sprinkler) whose area and volume were 4680m2 and 37206m3 respectively, was tested with 6 smoke evacuation fans activated at the beginning of the fire. The Total Fan capacity was designed as 10 volume/hour and 15 volume/hour, evaluated according to the maximum CO amount, vision and temperature by simulation for both situations. As a result of the tests performed, ideal visibility distance for evacuation and intervention was ensured with smoke fans at a capacity of 15 volume/hour.
