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.
[BLANK_AUDIO] [MUSIC] [MUSIC] Hi I'm Eric Rodin. >> And I'm Ray McCormack and we're the publishers and editors of Urban Firefighter Magazine. >> We'd like to welcome you to this segment of Fire Engineerings Training Minutes filmed at FDIC 2011 hands on training course. >> These training minutes are based on the urban essentials. The largest hot class at FDIC. Come visit us at urbanfirefighter.com. [SOUND] [MUSIC] >> Welcome to Training Minutes. I'm Lt. John Ceriello of New York City Fire Department and today we're going to be talking about a new tactic for the fire service, known as the KO fire curtain. Fires in highrise 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 highway, or the stairwell. That fire is always looking for that low pressure run or flow path from high pressure to low pressure. 1994 there was devastating fire in the Bronx, and two fire fighters from the FDNY began developing this device known as the KO curtain. It will essential 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 into that apartment and extinguish that fire. Or at least maybe get the door shut from the fire department into the hallway. What we gonna show you now is a deployment of the [UNKNOWN]. To deploy the KL curtain, first the firefighter will place the curtain on the sill. Once on the sill, the firefighter will take a measurements of his upper halyards. Once he has that measurement. He will then let the curtain drop up out of the window. it will unroll and the lower halyards will drop down into position. The bottom firefighter then grabs the halyard securing the curtain over the fire target window. The K.O. fire curtain is six feet wide and eight feet long. It has halyards both top and bottom, fifteen feet long, with stainless steel clips on the end. It also has aluminum stays, running through the fabric. That is fireproof and rated at 2,000 degrees. Those stays, don't allow the curtain to pillow into, the target window [sound effect] [music] [MUSIC] [MUSIC] What you've just seen is deployment of the [UNKNOWN] fire curtain. 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 that they can take their lines down and do a frontal attack on that fire. Thank you for watching Training Minutes. I'm Lieutenant John Cirello. [MUSIC]
