GOALS Establish good angles for hose advancement to the seat of the fire Maximize limited staffing by reducing the number of firefighters around the entry point Ensure that placement of the backup line does not bury the attack line Helps create organization of the fire ground Can help RIT crews with tracking the location of interior crews STEPS TO ACCOMPLISH Read the door swing in relation to the fire and any obstacles Position the hose line to the side of the do location. Doing so helps create one less pinch point. The goal should always be to avoid unnecessary pinch points that will create the need for another firefighter or unnecessary movement When possible, no more than two lines should enter through the same entrance Storm/screen doors should be removed prior to entry. If they are not removed, they will continue to be an obstacle during the fire Line placement should be no greater than a 45° angle to the door, or an extra pinch point will be created The inside of the door is defined as the 45° closest to the engine The outside of the door is defined as the 45° farthest away from the engine Click here to view Vector Solutions video on Splitting the Door Green lines Example of 45° angle to the door to avoid pinch points White line Midpoint to split the door.

Keep the attack and backup lines on different sides Inside of the door Defined as the 45° closest to the rig Outside of the door Defined as the 45° farthest away from the rig The attack line and coupling are deployed on one side of the door with hose flaked out aiming toward the target to reduce drag when advancing. This creates workable hose. Placing the coupling on the porch helps keep it from catching on the stairs or other obstacles.

Keep the attack and backup lines on different sides The attack and back up lines are clearly divided on each side of the door to create an organized front yard. This keeps the backup line from laying over top of the primary line Note: The backup line stays to its assigned half of the door and protects the egress stairs for the attack line. The backup line does not crowd the stairway.

The advantage is that both the male and female couplings are kept with the driver. The new section of hose is then added between the attack section. Second Edition 01/31/22 72 EXTENDING AT THE NOZZLE a minuteman shoulder load If the nozzle is a break apart nozzle, firefighters can just remove the tip and extend a hose line from the nozzle When using this method, care should be taken to ensure the break apart nozzle bale remains open during operation after the line has been extended. Consider tying off the bale of the break apart nozzle with webbing or a strap from the acme pack to ensure it remains open during operation If the break apart nozzle is not an option, the hose line will have to be shut down at the pump to allow the nozzle to be removed. The line can then be extended using one of the two options (acme pack or minuteman) Extending an attack line should not be done in an IDLH atmosphere. Ensure the crew is in a safe area to extend a line; they will have no water to protect them while the task of extending the line is being accomplished By using a break apart nozzle outside the IDLH atmosphere, the crew does not have to depressurize the attack line to add on additional hose. Here the nozzle firefighter is using a double donut roll. The advantage of this is that it keeps both the male coupling and the female coupling with the nozzle firefighter. This allows the connections to be made more quickly. Second Edition 01/31/22 73 Because a double donut roll was used, as soon as the new section of hose is connected to the break apart nozzle, the new section of attack line is ready for operation. Once the handline has been extended from the nozzle, the bale is now considered a critical safety point. Care should be taken to either continuously man the shut off or tie it open. Second Edition 01/31/22 74 GOALS Place a handline quickly and efficiently to positions that are out of the reach of preconnected handlines Can be accomplished using a 2 line with a gated wye or a water thief STEPS TO ACCOMPLISH Place the appliance approximately ten feet from the attack line s entrance point o There are situations where a decision must be made about where to place the appliance when using it for a vertical stretch o Try not to place the appliance directly in the entryway of the structure A garden stretch is commonly used on apartments/townhomes or condos; the length of the initial attack line should be enough to cover the fire apartment and one apartment adjacent to the fire apartment o Using o District familiarization and preplanning is key when selecting which hose line to pull off the engine and attach to the appliance It is preferred to have the backup line be supplied by a secondary 2 The backup line should match the length of the structure to ensure any fire extension can be reached VERTICAL STRETCH DROPPING THE BUNDLE DOWN acme pack is carried to the target landing. The female coupling is passed over the edge by the interior crews and dropped to the pump operator below. Depending on the layout of the landing, the hose can either be dropped over the top of the railing or through the railing spindles. Be aware that if the hose is dropped over the top of an open landing it must be minded while it is charged, otherwise the weight of the water will drag the hose back over the rail to the ground below.

With the appliance hose at the engine, connect it to the pump discharge, and charge it without having to wait for the acme pack to be connected to the appliance. The pump operator can then connect the acme pack to the appliance (If it has not already been done by the rest of the attack crew) and wait for the signal from the attack crew to charge the acme pack. The pump operator communicates with the attack crew and charges the handline before returning to the engine to verify the pump pressures. The nozzle firefighter should make sure they have their knee on the hose line prior to it being charged to prevent the hose from slipping back down. To combat the weight of the water pulling the hose down, the following general rule of thumb should be used: Two story stretch 50 fire floor landing Three story stretch fire floor landing Second Edition 01/31/22 76 VERTICAL STRETCH HOOK STRETCH -connected attack line was pulled from the hose bed and disconnected at the leader line to be used as the attack line in conjunction with garden stretch trunk line. The crew uses a pike pole to extend their reach, hook the bale, and perform a hook stretch. The hook stretch method should not be used over three stories. After the backup firefighter hooks the bale and pulls it up from the pump operator (photo above), the hook and nozzle are then passed up to the nozzle firefighter waiting on the third floor (photo on the right). Second Edition 01/31/22 77 After receiving the nozzle, the nozzle firefighter takes the attack line and flakes it out appropriately to the fire apartment door. Depending on the layout of the target landing, the hose can either be fed over the top of the railing or through the railing spindles. Be aware that if the hose is fed over the top of an open landing it must be minded while it is charged, otherwise the weight of the water will drag the hose back over the rail to the ground below. While the line is being flaked out for fire attack, the pump operator makes the connection to the trunk line appliance and waits for the signal to charge the line. The nozzle firefighter should make sure they have their knee on the hose line prior to it being charged to prevent the hose from slipping back down. To combat the weight of the water pulling the hose down, the following general rule of thumb should be used: Two story stretch the fire floor landing Three story stretch the fire floor landing Second Edition 01/31/22 78
