Egress Using a Sill Anchor

Tue, 31 Jan 2012|

Dan DiRenzo and crew demonstrate how a firefighter can exit a building during a Mayday using the windowsill as an anchor point--a last-ditch effort for emergency egress.



[MUSIC] [SOUND] Hi I'm Dan DiRenzo welcome to Fire Engineering's Training Minutes. In this segment, we're going to utilize a sill anchor to perform an egress with the person escape system. This fire fighter is wearing a lumbar mounted personal escape system. This option that we're going to utilize is going to be your last resort option. Realizing the hook into the sill is a very unsafe practice, do to the fact that the sill can fall firefighter out and he'll have an uncontrolled descent. You'd rather have the other options as far as remote anchor or the tensioned anchor deploy first, but if need be, you need to utilize the sill, we're gonna show you how that can be done. And this point, there's not other option. The firefighter is driven to this window. He's trapped in the upper floor, he's got himself a safe refuge, he's transmitting his Mayday. Once the firefighter gets to his window, he's gonna clear it, lay instructions. He's gonna determine he has a safe area to [INAUDIBLE] to. He's gonna deploy his system. He's gonna go down to his right leg. Run his hand up to the system, feel for his anchoring device, he gets ahold of his anchoring device, he deploys his system. He gives it two tugs to deploy that and get it off the safety line. Alright, with that done, the firefighter's really to anchor his off, his device. As you'll see here, the firefighter cuffs. The device. What he can do is put it between his two fingers. Comes up to the windowsill here. Now, once again, why it's unsafe is the construction of this sill leads to, for once the weight is on here, that this could either break off ro the hook could dislodge. So he can go either down into the sill. Or, his other option is, he can go into the side where he's got more structural stability. It's a fire fighter's preference at that point. The focus here needs to be keeping the hand cuffed over top of the hook, so that way when he goes to transition his way over, his extremities are not pinned underneath the rope or the hook. At this time the firefighter is going to lead out with his head staying down low and basically perform a window hang. When he performs his window hang he can now hang there before he goes in to full descent where they can either correct the problem, he can come back in the window or they can throw a ladder, an aerial ladder, back up to him and get him out. So the firefighter is going to go ahead and transition the window. As he transitions the window his left arm and left leg are gonna hook himself in. His right arm, with the escape rope is gonna be pinned into the outside wall. At this time, he determines there is no coming back in, he's gonna perform the rest of his egress. [SOUND]. He removes his hand, allowing the anchoring device to get established into the structure. He uses his left hand now as his throttle hand and control hand and his right hand will be his break hand, which goes to the lower back. But this time, he can now perform his controlled descent. [BLANK_AUDIO] Now, let's take a look at this in real time so you can get the good effect. The fire fighter has become trapped on an upper floor. At this time he's going to try to attempt an egress point, and transmit his firecom mayday. He's located his egress point and transmitted his firecom mayday. He's going to make the window a door and clear of all obstructions. His only other option is now to go at it with a sillo anchor, he deploys his system and embeds his hook into the structure. Hooking his left arm and left leg, he then completes his window transition and utilizes his right arm with the rope hooked to the outside wall. He transitions over the system and weights the system. This time he uses his left arm and left hand for his control and his right arm as his brake. Complete his controlled descent, and remove himself from the building. You just saw one of the techniques that can be utilized to establish an anchor point to safely utilize a personal escape system should a firefighter become trapped on an upper floor. It is strongly recommended the firefighters utilizing personal escape systems receive initial and annual training in the use of their system to maintain their proficiency. I would like to thank Sterling ___ for their sponsorship. Stay safe.
