Experimental Study on the Efficiency of Heptafluoropropane in Extinguishing Wood Stack and Oil Pool Fires

To study the efficiency of Heptafluoropropane (FM200) as fire extinguishing agent, several tests were done in ISO9705 room. It was observed that FM200 was effective on extinguishing both wood stack fire and oil pool fire, and all the fires were extinguished in 5 s. And FM200 could prevent the wood stack from burning again. Then, heat release rate and temperature in the fire room were depressed to a great extent by ejecting FM200. But it should be pay attention that the great pressure of the nozzle when FM200 be ejected in fire room may disturbed the flame and result in temperature rising for some bigger fires.
