Description: Academy instructors Manly Molton and Marc Lucero demonstrate the 7-9-8 coffin cut. It is of one methods we teach our FF's for venting a commercial flat roof with conventional construction. Using this cut allows the vent team to expand the hole quickly with only two additional cuts. Note after making the head cut and knockout cut, the right leg cut (vertical cut) is left twice as long as the head cut. This allows the hole to be expanded after the nine cut (bottom cut) is completed and the hole has been opened and cleared. Once this is done all that is needed is to lengthen the left leg cut and and additonal bottom cut ( the 8 cut ). for those that are unfamilar with the name it comes from the three steps it take to make this hole. Starting with the #7 the #9 expanding it to the # 8. The cut originated in the NYFD.

MarcLucero ::: Favorites Well only (21 years) and only one fire. Damn it! No really dude. thanks for the comment my thing is the roof is only weakend above the saw blade and forward of it. As long as your foot stays ahead of the cut on this secind cut your ok. Why your running a rafter. after that your right and as you see hands are switched to stay out of the danger zone (weakend part) But I like your thoughts and thank you for sharing it will provoke people to think of other things too! Be safe out there! 07-06-04 02:23:05 __________________________________________________
MarcLucero ::: Favorites I agree... Just the way this went down while we were teaching it at this moment. We verbally explained it and since this roof was frickin massive as you can see. we had plenty of time to let them make their own mistakes and learn from them. thank you for the comment. 07-06-04 02:17:16 __________________________________________________
MarcLucero ::: Favorites If you look a little closer you will see i am wearing protective glasses. you will see me adjust them at the end of the video after I set the saw down. so for all you eye protection guys. look a little closer I am wearing them. And as far as a full shield way to dangerous in too many other situations in my personal opinion. 07-06-04 02:14:47 __________________________________________________
rkettle ::: Favorites And lastly, when cutting a roof, a full face shield will protect your face as well as your eyes from flying gravel or other debris. These may sound like minor details, but when you are teaching recruits, it's all in the details. Be safe out there. 07-06-03 23:23:45 __________________________________________________
rkettle ::: Favorites When the hook man opens the vent hole, louver it the other way so he does not get a face full of smoke and heat. He also does not have to walk around the hole to pull the vent open like he did on the second one. For the sake a hose crew below, don't drop the pieces of roof into the building. 07-06-03 23:22:58 __________________________________________________
