Steel buildings are usually considered resistant to fire and fire accidents. Though, it may not be the case, all the time! Despite being a non-combustible material, steel has a high heat conducting value that contrarily affects its performance during exposure to fire. In order to solve this problem, prefabricated steel buildings need to be designed with a requisite amount of expertise and experience. It is precisely for this reason that the materials used in the construction of these steel buildings must possess certified and tested values for fire ratings, which tend to affect their performance and efficiency during a fire encounter.
Steel storage buildings are often subjected to fire accidents, due to the presence of hazardous chemical substances. During a fire exposure, the temperature levels go up at an alarming pace. The higher temperature levels adversely affect the efficiency of steel building structures. They usually lose their strength and stiffness at such high levels. Steel has a high very high thermal conductivity. Thus, the heat tends to spread through the entire steel structure through conduction, convection or radiation modes.
Steel Buildings Fire Designs – Important guidelines
To increase the resistance of the prefabricated steel buildings against fire exposures, a few pointers need to be taken into consideration. A thorough knowledge and expertise of fire rating values of steel structures should be taken into account during the designing stage.
Proper ventilation must be ensured in the steel building structures to evade such encounters. A sound ventilation process also helps in evacuating the heat and gases, in case of a serious fire accident. In addition to this, sound arrangements must be made for easy availability of water and fire extinguishers in case of a mishap. Besides, a proper fire engineering design can also assist a great deal in preventing the fire spread.
These are a few guidelines which if kept in mind, can serve a long way in protecting prefabricated steel buildings against the risks of fire exposures.
