Specifications for Fire Extinguishers at Asphalt Loading Platforms
Thread Content
The asphalt loading platform has 4 crane positions. The loading area is about 100 square meters. May I ask if a 8-kilogram push-type fire extinguisher should be installed, and are there any relevant regulations? Thank you
GB50140-2005 Code for Design of Fire Extinguisher Installation in Buildings: When the flash point of asphalt is greater than 60 degrees, it is considered a Class B fire hazard area; the risk level is classified as medium. The minimum required extinguishing capacity per fire extinguisher is 55B. The maximum protected area per unit fire extinguishing rating U is 1.0 m2/B. For areas where Class B fires occur, foam fire extinguishers, sodium bicarbonate dry powder fire extinguishers, ammonium phosphate dry powder fire extinguishers, carbon dioxide fire extinguishers, water-based fire extinguishers designed for Class B fires, or halon fire extinguishers should be used. Dry powder fire extinguishers of 4 kg or higher capacity can meet the requirements. Based on the 8KG of dry powder you mentioned, the fire extinguishing rating is 144B. There shouldn’t be any cart-style versions for 8kg; I suspect you’re mistaken. S Q = K —— where K is set to 0.3, S=100, and U=1; thus Q = 30. The minimum required fire extinguishing capacity at each fire extinguisher installation point within the calculation unit should be calculated using the following formula: Q Qe = —— where Qe=144; hence N=30/144≈1. N is also because a computing unit has no fewer than 2. Therefore, 2 8kg dry powder fire extinguishers are sufficient.
