Commercial Ventilation Operations Why the Pull-Back Method doesn’t Work Firetown Truck Operations The strapping that anchors the purlins to the joist Firetown Training Specialist

3/8 All Thread is utilized to anchor the waterlines and sprinklers lines from the joist Firetown Training Specialist

Pull-Back Method “I have performed both pull-backs and drop panels in my 20 year career assigned to Truck Operations and during that time, I have experienced little success with both operations. The pullback method requires four person engine companies and significantly decreases structural integrity. The drop panel is dangerous to anyone operating underneath this section of roof. You are basically creating a ROOF COLLAPSE situation on firefighters operating inside. Nobody can be completely assured that the panel will not strike and injure/kill a firefighter below.” Ed Hadfield Truck Captain, Huntington Beach Firetown Training Specialist

Pull-Back Method When utilizing this method you are cutting through structural members and you will be unable to pull it back with the water line strapping attached to the joist “During the pullback method the sawyer is needlessly exposed to smoke and heat as the panelized section is being pulled up in front of him.” Ed Hadfield Truck Captain, Huntington Beach Firetown Training Specialist

Louver-in-Lieu Method When utilizing this method structural integrity is not compromised because you are rolling the structural members. Additionally the strapping will not hinder the success of your operation Firetown Training Specialist

Louver-in-Lieu JOIST “A” First cut ID Cut Second Cut JOIST “B” Third and last cut P U R L I N P U R L I N JOIST “C” Repeat Process M A I N B E A M • Louver-in-Lieu • Make the first cut parallel to JOIST “A”, cutting as close to the joist as possible without cutting into it. One firefighter will be on each purlin and reach in halfway. • Make the second cut starting at JOIST “A” far enough from the purlin as not to cut into the joist hangers. Roll rafter “B” and finish the cut just short of rafter “C” • Make the third and final cut reaching out halfway above JOIST “C” back to the purlin. Firetown Training Specialist

Strip Against Construction #2 cut #3 cut louver Your First cut will be done by the Captain and will be a “head cut” (only cut deep enough to cut through the plywood) Firetown Training Specialist

Strip Against Construction • The first cut head cut is done by the (Captain) When doing this cut you will reach out as far as possible and just do a skim cut (enough to only go through the decking). When finished the Captain will then watch for overall safety concerns. • The second cut( Firefighter) will start on the inside of rafter “A”. Then cut parallel with the purlin rolling over rafter “B” and stopping at rafter “C”. Continue this as far as needed. • The third thing to do is louver (Engineer/AO) the cuts and clear out any insulation or ceiling below the louver.
