This is an experimental study that analyzes the fire resistance performance of the types of glass installed in an opening to prevent a fire from spreading through the opening. The fire resistance test for glazed elements (KS F 2845) was performed on four materials: laminated glass, general glass, double-layer glass, and toughened glass. To analyze the risk of fire of each glass type, the temperature prediction of the fire room in the building was analyzed. As a result, the laminated glass ruptured at 617 ℃, and it was found to be the most resistant to heat amongst all the glass types. Additionally, the temperature of the fire in the compartment was predicted to reach 617 ℃ in 3 min. A performance review is required for the glass installed in the opening to prevent the fire from spreading.

This paper reports the investigation on the fire resistance performance of reinforced concrete column with embedded permanent formwork from woodwool board (WWCB). A series of slender column embedded with and without WWCB with cross-sections 200 mm x 200 mm for column without WWCB and 300 mm x 300 mm with embedded 50 mm thick WWCB. The height of the slender column was 2000 mm. The fire resistance test was performed in accordance with BS 476-22:1987 for two (2) hours fire exposure. The fire resistance test for the embedded column with WWCB was classified as “good” in resisting fire and heat transfer.

The structure of high-speed roller door with water film has improved in this study. The flameproof water film system is equipped with a water circulating device to reduce the water consumption of water film system. The water film is generated at the roller box of the high-speed roller door in this study. The heating test is done with the full-scale heating furnace. Both cases of the water film on unexposed surface and water film on exposed surface passed the fire resistance test based on ISO 834, proving that the high-speed roller door with water film system has 120A fire resistance period. The main findings indicate that the water film on exposed surface shows that as the amount of water film evaporated by high temperature inside the furnace must be greater than the evaporation capacity of water film on unexposed surface, the required water supply is 660 L more than the water film on unexposed surface.

Resistance Performance

Composite beam using asymmetric H-shaped steel is one of the constructional structures developed in the advanced countries in Europe since early 1990s. The purpose of this study on composite beams where H-shaped steel is partially laid in concrete slabs was to find how to design fire protection and improve fire-resistance to make deep deck plates provide the beams with advantages upon a fire and to improve stiffness in structural aspect. Only lower flange which is directly exposed to a fire was included in fire-resistance design in order to decide optimal fire- protection design condition and test was conducted for spray-coating and paint-coating. In the fire resistance test, web thickness and lower flange thickness were varied to derive the optimum condition for improving fire-resistance performance. It was observed from the test that 90-minute-protection employed to lower flange provided fire resistance for 3 hours. It was also observed that the basic shape resisted fire for 89 minutes, while web reinforcement and lower flange reinforcement provided fire-resistance for 112 and 157 minutes, respectively. The result showed that lower flange reinforcement is the most effective way to improve fire-resistance.

Abstract Reinforced Aerated Concrete panel building systems are preferred as wall elements in residences and industrial facilities due to their advantages. The signal issue encountered in industrial facilities is caused by fires that occur. Fire resistance of sustainably reinforced aerated concrete panels was investigated. The wall G3/05 class reinforced panel model to be used for the test was preferred. The panel wall has been subjected to a 120-minute fire resistance test. In this process, 1050 C° temperature was measured on the surface exposed to flames, while the wall temperature was read 50 C° on the other surface, and the heat temperature increased to 70 C° only at the panel joints. The data obtained from showed that the reinforced aerated concrete panels maintain their integrity under fire and resistant to high temperatures. These data that reinforced aerated concrete systems should be preferred, in buildings with human population and high fire risk.

One of the major challenge from unplanned growth in the cities is the fire incidents posing a serious threat to life and property. Delhi, the capital city of India, has seen unplanned growth of colonies resulting in a serious concern for the relevant agencies. This paper investigates the relation between potential causes of fire incidents during 2013-2016 in South-West Delhi Division of Delhi Fire Services as part of risk analysis using the data about fire stations & their jurisdictions, incidents of fire, water reservoirs available, landuse and population data along with the divisional & sub-divisional boundaries of South-West Delhi division under Delhi Fire Service. Statistical and Geospatial tools have been used together to perform the risk analysis. The analysis reveals that difference in actual occupancy and defined landuse as a part of unplanned growth of settlements is found to be the main reason behind the major fire incidents. The suggested mitigation measures focus on legal, policy, physical & technological aspects and highlight the need to bring the systemic changes with changing scenario of demographics and infrastructure to accommodate more aspects of ground reality.

Polymer composites filled with metal derivatives have been widely used in recent years, particularly as flame retardants, due to their superior characteristics, including high thermal behavior, low environmental degradation, and good fire resistance. The hybridization of metal and polymer composites produces various favorable properties, making them ideal materials for various advanced applications. The fire resistance performance of polymer composites can be enhanced by increasing the combustion capability of composite materials through the inclusion of metallic fireproof materials to protect the composites. The final properties of the metal-filled thermoplastic composites depend on several factors, including pore shape and distribution and morphology of metal particles. For example, fire safety equipment uses polyester thermoplastic and antimony sources with halogenated additives. The use of metals as additives in composites has captured the attention of researchers worldwide due to safety concern in consideration of people’s life and public properties. This review establishes the state-of-art flame resistance properties of metals/polymer composites for numerous industrial applications.

Improving the fire resistance of the key cables connected to firefighting and safety equipment is of great importance. Based on the engineering practice of an oil storage company, this study proposes a modification scheme that entails spraying fire-retardant coatings on the outer surface of a cable tray to delay the failure times of the cables in the tray. To verify the effect, 12 specimens were processed using five kinds of fire-retardant coatings and two kinds of fire-resistant cotton to coat the cable tray. The specimens were installed in the vertical fire resistance test furnace. For the ISO 834 standard fire condition, a fire resistance test was carried out on the specimens. The data for the surface temperature and the insulation resistance of the cables in trays were collected, and the fireproof effect was analyzed. The results showed that compared with the control group, the failure time of the cable could be delayed by 1.57–14.86 times, and the thicker the fire-retardant coatings were, the better the fireproof effect was. In general, the fire protection effect of the fire-retardant coating was better than that of the fire-resistant cotton.
