FDNY Lt. John Ceriello discusses the K.O. Fire Curtain, a device developed primarily for high-rise fires that used to block wind, thereby allowing an interior team to more easily attack a fire.
[SOUND]. Hi, I'm Eric Roden. >> And I'm Ray McCormack and we're the publishers and editors of Urban Firefighter Magazine. >> We'll like to welcome you to this segment of Fire Engineering Training Minutes filmed at FDIC 2011 Hands On training program. >> These training minutes are based on the urban essentials. The largest [UNKNOWN] class at FDIC. Come visit us at Urbanfirefighter.com. [NOISE] [MUSIC] >> Welcome to Training Minutes. I'm LT John Ceriello of the New York City Fire Department, and today we're gonna to be talking about a new tactic for the fire service, known as the K.O. fire curtain. Fires in high-rise buildings are always a challenge. When wind enters a structure that has a fire in it, it creates a high pressure zone, increasing the heat release rate of that particular fire. The fire service is coming from, most likely, a low pressure area, namely the hallway, or the stairwell. That fire is always looking for that low pressure run or a flow path from high pressure to low pressure. In 1994, there was a devastating fire in the Bronx and two firefighters from the FDNY began developing this device known as the KO curtain. It will essentially block the wind allowing the inside teams to make an entrance and frontal attack on that given fire. Essentially, by blocking the wind, we decrease temperatures in our fire department. And we also take away the push of the wind so that those lines can make it down that hallway enter that apartment and extinguish that fire. Or at least maybe get the door shut from the fire department into the hallway. What we're going to show you now is the deployment of the KO curtain. To deploy the kale curtain, first the firefighter will place the curtain on the sill. Once on the sill the firefighter will take a measurement of his upper halliards. Once he has that measurement, he then will let the curtain out of the window. It will unroll and the lower halliards will drop down in position. The bottom firefighter then grabs the [UNKNOWN] securing the curtain over the fire target window. The KO fire curtain is 6 feet wide and 8 feet long. It has [UNKNOWN] both top and bottom, fifteen feet long, with stainless steel clips on the end. It also has aluminum stays running trough the fabric that is fire-proof and rate at 2000 degrees. Those stays don't allow the curtain to pillow into the target window. >> [MUSIC] [MUSIC] [MUSIC] >> What you've just seen is deploment of the KL Fire Curtian, it's a device being carried on all truck companies in the New York City Fire Department. That device is being taken into any fire in a high rise building by the roof man going to the floor above and deploying the curtain over the target window which is being impacted by wind. It is creating a much safer environment for firefighters to function in the hallways so they can take their lines down and do a frontal attack on that fire. Thank you for watching Training Minutes. I'm Lieutenant John Ceriello.
