5 Questions should be noted that steel plant fire

5 Questions Hainan steel plant fire must be noted
01 Hainan Steel plant fire risk identified
Fire risk by production, storage items and process to jointly determine. As a plant different dangerous production, use or storage of different dangerous substances, the fire protection requirements are different. Including dynamic changes in production stage, it may cause a fire hazard changes. Thus, the beginning of the design should fully understand the process, raw materials, semi-finished products, consider the possible future risk of high-grade clean workshop area, avoid leaving the subsequent development.

02 Hainan Steel plant fire district level
In the absence of specific process requirements of the situation, as far as possible the division of the fire district, helps to reduce the spread of fire, fighting for the evacuation and provide favorable conditions. Should be separated by local fire district fire load piled on large parts of a large amount of combustible combustible materials as the focus, according to the way the fire spread, binding column reinforcement, the rational use of effective partition firewalls, fire shutter, water screen and so on.
03 Hainan Steel plant material sandwich panel walls
Since the combustible filler material, the fire resistance of polystyrene material is very low, the use of such a building, fire load can be increased by 9% to 30%, in case of fire, can accelerate the temperature dependence of the steel, leading to construction the rapid collapse. Therefore, the low level of the plant should be strictly controlled to switch to a higher risk of fire use. Experts recommend the use of glass wool or cotton, both a fire burn, the building did good fire protection, if you want to use a polyurethane core material can, Henan ten million production of polyurethane sandwich panels can achieve fire rating B1 level to fire at the same time also did a very good insulation properties.
04 Hainan Steel plant quality fire retardant coating
Fire retardant coating varies quality and low price, some units in order to save investment options of poor quality fire-resistant coating; and steel body design life is generally 50 years, while the life of fireproof coatings is much lower than 50 years, companies generally less likely to fire on their own again after brushing paint failure would have resulted in the use of post-coated steel will not achieve the role of fire in the fire-resistant coating thereon.
05 Hainan Steel plant fire smoke ventilation
Most of the existing plants are natural ventilation smoke, compared with mechanical exhaust many advantages, the domestic soluble natural ventilation window in the steel plant to use more appropriate, to meet the lighting needs at the same time be able to play the fire smoke. Under other natural weather conditions, outdoor wind speed is smaller, is on top of the smoke above the fire source faster as the wind speed increases, the flue gas is blown toward the back side of the wind, natural smoke effect is reduced. Thus, similar to the construction of the roof power station plant may consider adding skylights in place or increase the vents on the walls, in the smoke fire rescue, rescue walls and doors and windows should be upwind, smoke quickly, reduce fresh air into the fire , can effectively slow down the development of the fire.
