Difficult to function as a large shopping mall fire protection shutters, fire, radiant heat

[Korea financial newspaper gimmingyeong News] fire automatic fire protection shutters are installed to prevent the spread of fire was a normal operation even if would have been placed by the combustibles such as clothing adjacent to the peripheral showed possible the spread of fire by radiation passing through a fireproof shutters.

Korea Fire Protection Association conducted a mock (Mock-up) for the experimental evaluation of fire spreading due to the radiant heat transfer through the fire in the 12th fire protection shutter when laying Disaster Testing Institute.

Experiments to install the radiant heat meter in distance 0.5m from the fire protection shutter was conducted for 20 minutes fire test according to the method of KS Standard (KS F 2268-1) specified in the Ministry of Transportation Notice No. 2016-193 intended for steel fire protection shutter by measuring a radiant heat, and places the garment or the like was observed with the naked eye whether or not complexed.

Result of radiation from the distance 0.5m apart from the heating fireproof shutters at 18 minutes was ignited 14.8 ㎾ / ㎡ paper boxes and clothing around the melt. By surface clothing material or cotton blends while the immediately ignited by the radiation heat, the polyester was characterized by a strip-ignition after the melt flows down.

According to the relevant standards, if radiation is 2.5 ㎾ / ㎡ one time when the human body that can withstand is about 30 seconds, 10 ~ 20 ㎾ / ㎡ be known to the general combustible ignition.

Fire Insurance Association official said, "large quantities of flammable substances was not the case of a large shopping mall positioned for efficient use of space, the spread of fire risks associated with most passing through a fireproof compartment, but fire protection shutter fireproof shutters radiation are compared at all" and "gross floor area the 3000 ㎡ over many domestic large-scale stores (948 points) appeared to be in need of improvement of the heat shield performance criteria such as the introduction of fireproof shutters that are exposed to the risk of fire spreading, "he said.

In addition, "a large shopping mall officials themselves firefighting facilities installed maintenance and in accordance with the provisions of the law relating to safety management leave build things around fireproof shutters Regulations, such as prohibiting obstacles installation compliance is required" and "part of the adjacent placement of flammable inevitable consultation with relevant agencies to improve the standards, such as to install a fireproof shutters with heat shield performance for nagagetda, "he said.
