Apparatus Positioning Effective apparatus positioning is critical to pumping operations, deployment of aerial apparatus and general incident control. You must position your apparatus in an area where it is most effective, while keeping the apparatus, yourself, and your crew out of harm’s way. Driver/operators must consider many factors when positioning their apparatus—including the fact that additional emergency vehicles may arrive after them.

Pumper Course M5T2-3 Screen Text A fire apparatus has just responded to this incident. Most departments have standard procedures for positioning apparatus at an incident. However, standard procedures cannot possibly cover all situations. The ultimate decision of apparatus positioning rests with the fire officer in charge. Is the spot chosen for this apparatus a good one? Select the various components of the graphic. (Pop-up text 1) Hydrant Will this pumper need additional water? If so, the driver/operator should have laid a supply line as the pumper went up the driveway to the house. (Pop-up text 2) House Old structures can collapse during a fire. Always position your apparatus outside of the collapse zone of the structure—approximately equal to the height of the structure. (Pop-up text 3) Front Doors Always position your apparatus for effective rescue. This pumper is on the side opposite of the front doors and windows of the house. Is this the best spot? (Pop-up text 4) Power Lines Never park an apparatus under power lines that could interfere with the use of aerial devices or even fall on the apparatus during a fire incident. (Pop-up text 5) Apparatus What’s your method of attack? Will hand lines reach the seat of the fire? Are you within the effective range of aerial master streams, elevated platforms or turrets? Pop-up text 6) Trees Protect your apparatus! The fire could spread to surrounding trees. Can you easily reposition your apparatus if conditions change? Pop-up text 7) Wind and Slope Notice the slope around the house. For structural fires, try to park upwind and uphill from the fire. In this way, you avoid air-borne contaminants and runoff from the fire. Also, master streams directed into the structure will push fire back to the burning areas and NOT toward unburned areas. Pop-up text 8) Staging (Out on Main Street) Your apparatus may not be needed immediately. The fire officer in charge may assign you to a staging area where you will wait for an assignment.

Pumper Course M5T2-9 Screen Text As a driver/operator, you should follow these basic hydrant guidelines. § Hard suction hoses should never be connected to a hydrant. Their couplings have

been known to fail, and they are designed for drafting from static sources, NOT for positive pressure conditions.

§ The best hose is a large diameter, soft intake hose between 10 and 50 feet in length. § Many districts require a gate valve on the smaller hydrant discharge before

connecting to the larger discharge. This allows additional hoses to be connected without interrupting the flow of the larger connection.

Pumper Course M5T2-10 Screen Text In a forward lay, also called a straight or feeder lay, a pumper drops a supply line at the hydrant and moves forward to the fire. Advantages: § Allows the driver/operator to be at the fire scene and keep a visual on changing

circumstances § Forward lays using large diameter hose have virtually eliminated the need for reverse

lays due to the large quantity of water delivered § Forward lays keep the apparatus at the fire so that aerial devices are available for use. On forward lays, a four-way hydrant valve is usually installed to allow additional lines to be connected without interrupting the flow in the first line.

connections § The pumper can stay at the hydrant to boost hydrant pressure or be used in relay

operations Disadvantages: § If only one pumper is responding, you need to drop critical equipment at the fire scene

before doing the reverse lay § Keeps the driver/operator at the hydrant instead of at the fire scene Audio Production Elements Type Description Source

Pumper Course M5T2-15 Screen Text A relay pumping operation is used when the water source is remote from the fire incident. A source pumper is stationed at the water source and one or more additional pumpers “relay” the water through their pumps to the apparatus at the fire scene. Pass your cursor over each item in the relay chain to see what it is. Then, select each item to learn more. (Pop-up text 1) Source Pumper The design of a relay pumping operation is driven by the desired flow at the fire scene. A supplying pumper must provide the next-in-line apparatus with at least 20 psi of intake pressure. This reduces the possibility of damage to the apparatus pumping system. The driver/operator of the source pumper must communicate the pumping capacity to the Incident Commander, along with any hose and pressure changes during the operation. If available, a fixed or portable pump can substitute for the source pumper.

(Pop-up text 2) First Relay Pumper Since there can be sudden pressure fluctuations in relay operations, relay pumpers must have intake pressure relief valves (if available) set at 10 psi above the discharge pressure of the previous pumper to dump water as needed. Select the underlined text to learn more. (Pop-up text 3) Intake pressure relief valves These valves are used to reduce the potential for damage to the pump or hoselines due to water hammer, which is caused by pressure fluctuations. A pressure relief valve can be part of the pump itself or screwed onto the pump intake connection. Each driver/ operator must ensure that flow psi never exceeds rated pump capacity and communicate any problems to the Incident Commander. (Pop-up text 4) Second Relay Pumper Relay pumpers must have a method of bleeding air from hoses being charged with water. This may be done through opening unused discharge valves or through the use of a built-in bleeder valve. Select the underlined text for more information. (Pop-up text 5) bleeder valve A bleeder valve can discharge large quantities of air when the line is being charged with water. It’s important for the driver/operator to monitor the pressure control devices and bleeder valves on pumps and hose connections. (Pop-up text 6) Incident Commander The Incident Commander must look at the fire attack to determine the desired nozzle

pressure needed at the fire scene. Factors that can determine desired pressure include the use of elevated master streams, hose type, hose size, pump discharge pressure, and elevation changes from the water source. Based on these factors, the commander must design a system that can deliver this pressure. (Pop-up text 7) Attack pumper The attack pumper can only fight the fire for a limited amount of time (depending on the size of its water tank and the amount of water being discharged). Keep in mind that establishing a relay operation is not a quick process, and you may run out of water before a permanent resupply is in place.

Pumper Course M5T2-16 Screen Text There are two ways to set up a relay pumping operation:

<See Production Elements for screen text> The Constant Pressure Relay method is more common. Select each item to learn more. Audio Production Elements Type Description Source

Graphic 1 Modified graphic from M4T1_12 (M5T2-15 in old Pumper course) with no pumpers, driver/operators or lines. There are two hot topics:

Constant Pressure Relay method Maximum Distance Relay method



Constant pressure M4T1_14 Maximum distance M4T1_17

Notes I have added initial caps to the names of these two methods. I made this screen a decision point so students return to this screen to select the second relay method. It was confusing to flow from one method to the second without acknowledging that the discussion of the first method had ended.


1/4/2017 Draft


Pumper Course M5T2-16a Screen Text The Constant Pressure Relay method is the simpler of the two relay methods. It has some advantages and disadvantages. Advantages:

• The length of hose and the pump pressure is predetermined. The driver/operator does not need to await specific instructions.

• Eliminates complex pump calculations. • Driver/operators in the relay only have to maintain one constant pressure. • Reduces radio traffic and confusion.

Disadvantages: If small diameter supply lines (2 ½- or 3-inch) are used then they:

• Limit the total gallons available per minute (gpm) • May not provide adequate pressure due to high friction loss • Limit the distance between apparatus to approximately 750 feet

Pumper Course M5T2-16b Screen Text Here is a constant pressure relay pumping operation. Pass your cursor over each item to see what it is. Then, select each item in the relay chain to learn more. (Pop-up text 1 for source pumper) In a Constant Pressure Relay method, the source pumper and all relay pumpers pump water at a constant 175 psi using a single hose size. It’s crucial to have continual communication between all parties in order to ensure correct pressure and to update each other on changing circumstances.

(Pop-up text 2 for relay pumper) It’s important that each pumper has an automatic pressure control valve to control accumulative pressure changes. As in any relay pumping operation, it is important for each driver/operator to ensure that flow psi never exceeds rated pump capacity. (Pop-up text 3 for attack pumper) The attack pumper uses an open discharge or secured waste line to handle excess pressure. When shutting down a constant pressure relay, start with the attack pumper and work backwards to the source pumper.

(Pop-up text 4 for “dump line”) A dump line may be either an open discharge valve or another hoseline not currently in use. It is used to relieve excess water pressure (psi) when the apparatus intake exceeds 50 psi in a relay operation. (Pop-up text 5 for box #4) Have the source pumper start pumping water at 175 psi.

(Pop-up text 6 for box #5) Have each relay pumper close its discharge valve once a steady flow of water reaches it, then advance the throttle to 175 psi.

(Pop-up text 7 for box #6) Once a pumper is on-line, have that driver/operator set the intake pressure regulating device (if available) to 10 psi above the input pressure.

(Pop-up text 8 for box #7) Have the driver/operator of the attack pumper adjust discharge pressure to supply attack lines.

Pumper Course M5T2-18a Screen Text The Maximum Distance Relay method uses a calculations table. First you enter the required flow in gpm. Then you enter the hose diameter you have available. The table then shows you the maximum length of hose you can use to deliver this gpm (see next screen). Advantage: • Gives you greater flexibility for establishing the relay operation by allowing longer

hose lays than the constant pressure relay method set up. Disadvantages: • Maximum hose distance must be calculated based on gpm required and hose diameter. • Requires greater communication between the driver/operators on the relay. • Number of apparatus may vary due to the actual amount of hose carried on each

Pumper Course M5T2-20 Screen Text A tandem pumping operation is a modified version of a relay pumping operation. It is used when the pressure needed is higher than a single engine is capable of supplying, such as high rise sprinklers, standpipe systems, or very long hose layouts. The first pumper is positioned at a hydrant. A second pumper is placed within 300 feet of the first pumper to boost the pressure in the first pumper’s supply line.

Pumper Course M5T2-20b Screen Text In comparison to a tandem pumping operation, a dual pumping operation requires the pumpers to be parked side-by-side and connected intake-to-intake. This type of operation allows one strong hydrant to supply two pumpers. The second pumper uses the excess water from the hydrant that is not being used by the first pumper. This allows each pumper to perform a separate operation from the same water source. Audio Production Elements Type Description Source

Still 1 See Pumper Course, Operations, Apparatus Positioning, Page 21 of 25. Recommend some textual changes and a reshoot of Still 1


Back M4T1_20 Notes This is a little confusing to me. Does the hoseline split and send some water to each intake of each pumper? The still does not clarify how hoselines are connected. I think we could keep the still but add an overlapping graphic of how the hoselines are connected from the hydrant to the two pumpers. Also, if we are going to reshoot this, I think we should put some aerial devices on the pumpers and show how tandem pumping operations can be used to support a master stream on an elevated platform.

Screen Name Content Reference/Screen Reference M4T1_22KC NFPA 5.2.4, M4T1_19 Screen Text Now let’s see if you can set up a maximum distance relay pumping operation. There is a lake 2,100 feet from the fire. You have four pumpers available, each with 1,200 feet of 4-inch hose, and you need 750 gpm at the fire scene. Drag and drop each needed pumper onto the relay line. Make sure that each pumper is properly located. Select the Maximum Distance Chart icon to review the chart. Audio CA Excellent work! You properly determined that you needed three engines and you did not

exceed the maximum allowable distance for 4-inch hose flowing 750 gpm, which is 1,450 feet.

IA1 Remember to divide 2,100 by 1,450 from the chart, and determine the maximum allowable distance for your hose layout. Try again.

IA2 No. The maximum allowable distance between pumpers is 1,450 feet. Since the total distance is 2,100 feet, divide 2,100 by 1,450 = 1.5. Then 1.5 + 1.0 = 2.5. Rounding up you need 3 pumpers--one stationed on each end and one in the middle of the 2,100 feet.
