6/6 ENGINE EVOLUTIONS 1 6/6 ENGINE EVOLUTIONS ENGINE EVOLUTIONS -01. ENGINE COMPANY OPERATIONS Most commonly, the primary responsibility of an engine company is to apply an extinguishing agent to an existing fire. Although engine company members are often required to perform tasks other than agent application, this Chapter of the Drill Manual is dedicated to the various evolutions used to provide water to a fire. There are many factors which will determine the type of hose evolution to be applied in a given situation. Whether or not fire is visible during response, the volume of fire, the location of the fire, exposure problems and potential life hazard are but a few of the factors which will determine the size and number of lines to be used. This information is taken into account by the first arriving officer. The method of choice must be put into operation quickly, safely and effectively..01 THREE TYPES OF ENGINE COMPANIES 1. Single Engine Company: One apparatus, staffed by a Captain, Engineer and two Firefighters. 2. Two-Piece Engine Company: Two Apparatus. The lead engine is staffed by a Captain, Engineer and two Firefighters. The 200 Series engine is staffed by one Engineer. 3. Light Force Company: The truck is staffed by a Captain, Apparatus Operator and two Firefighters. The 200 series engine is staffed by an Engineer and a Firefighter..02 TWO PHASE OF A HOSE EVOLUTION 1. Supply Phase: That phase of a hose evolution which allows the engine apparatus to secure a constant source of supply from a hydrant. 2. Fire Fighting Phase: The removal of the selected line or lines from the apparatus and the advancement of those lines to the objective..03 FORWARD AND REVERSE EVOLUTIONS 1. Forward Evolution: (Hydrant to fire) The type of hose evolution which begins with the laying of a line from a hydrant or other source of supply. Supply Phase should be completed first. 2. Reverse Evolution: (Fire to hydrant) The type of hose evolution which begins at the fire and proceeds to the hydrant or other source of supply. Fire Fighting Phase should be completed first. 6/6 ENGINE EVOLUTIONS 2.04 POSITIONS OF MEMBERS Engineer The driver of the apparatus. Completes the supply phase in a forward evolution. Assists in removing hose and equipment from the apparatus. Breaks proper coupling and supplies fire fighting phase with water. Replaces slack hose. NOTE In above ground hose evolutions, the Engineer may be required to perform additional functions to complete the evolution. Nozzle Member Rides in the right-front jumpseat of the apparatus. Acquires nozzle, attaches nozzle, advances nozzle and slack hose to objective. Hydrant Member Rides left-front jumpseat of the apparatus. Lays the line with the 4-way valve. Supplies engine with water at proper time. Replaces hydrant tools. Assists officer and nozzle member in advancing lines, etc..05 FIFTH POSITION ON APPARATUS-(TWO PIECE) Engineer-200 Series: Drives second pumping apparatus in a two-piece engine company. Supplies water from hydrant to lead apparatus. NOTE When the 200 series engine is positioned at the fire, the Engineer performs same operations as the engine Engineer. -02. BASIC OPERATIONS Hose-evolutions are performed by members so that water may be applied to an existing emergency situation in a timely, efficient and safe manner. Each hose evolution is an accumulation of several "Basic Operations." Prior to engaging in complete hose evolutions, each member must have a complete understanding of, and be able to perform, each of the "Basic Operations."'.01 TERMINOLOGY Brass This refers to couplings and fittings. A general term for any fitting. Couplings Couplings are to be hand-tight, unless conditions warrant the use of a spanner. Dressing the hose Make it orderly. This enables finding the hose patterns. It also removes some of the kinks from the hose before it is loaded. First Fold Forward Lay Used to provide the first section of 2-1/2" hose on the ground behind the apparatus. Folds at the objective Folds are laid away from the objective and toward the source of supply (when possible). This places the nozzle and the couplings in proper position for advancing. Hose Sling 6/6 ENGINE EVOLUTIONS 3 Consists of two snap hooks that lock automatically and is a single continuous loop approximately 5' long made up of nylon webbing similar to that used in summer belts. It is carried pre-attached to the 4" hose for laying a line on two-piece engine companies only. Natural Grip The same grip used to shake a hand (thumb up). Used when making and breaking couplings behind the nozzle. Nozzles When a nozzle is connected or grounded, it shall be shut off in all cases. When grounded, the hose is straightened for at least 5' behind the nozzle. Proper Hose Grip Keep thumb against index finger (not around the hose) when handling it. Injuries to the thumb will occur if the hose hangs up on the apparatus or other objects. Exceptions: 1. Making or breaking couplings. 2. Attaching or removing nozzles. 3. Making a one-member fold. 4. Bedding hose in apparatus. Hose grip Pulling Folds (Arm Position) Used to place additional hose on the ground behind the apparatus. The hand and arm which are pulling a fold shall be straight. This is to prevent arm injury if hose should hang up in hose bed. Pulling folds Running Line Used to provide a coupling in the work area. Stay out of the Folds 6/6 ENGINE EVOLUTIONS 4 When executing a hose lay, or anytime when handling hose, stay out of the folds. Injury can result from becoming entangled in the hose. Stealing Hose from the Lay Taking hose away from the fire fighting phase of the hose lay. When handling 1-1/2" and 1-3/4" hose, a member may, if coupling is within 3' of a discharge gate, pull the coupling back into the work area and break it. In above ground hose lays, if there is sufficient hose at the base of the objective, a member may steal from the lay. Sufficient Slack Used to provide sufficient slack hose on the ground for an extension lay. Tailboard Area When preparing to break couplings coming out of the hose bed, always pull 4" and 2-1/2" couplings to within 3' of the tailboard before breaking. Pull 1-1/2" and 1-3/4" couplings to within 3' of running board, at the transverse hose bed, before breaking. This will make it easier to bed the coupling. Unnatural grip Little finger up (reverse of natural) grip. Used to remove nozzles from the apparatus. Work area An area 3' out from the side of an engine apparatus starting at the rear axle and extending 8' to 10' to the rear of the tailboard. Work area NOTE This area is also referred to as the "danger area.".02 PULLING A RUNNING LINE Requirements: 1. Stand on the ground, behind the apparatus, to the side the running line is meant to be pulled. Face to the rear. (Figure 5) 2. With the hand next to the hose, grasp the hose with the proper grip (grasp from beneath the hose). 3. Proceed toward the rear, always facing the direction of travel, until a coupling drops into the work area. 4. If pulling a running line for a supply line, ensure that sufficient hose has been removed to reach the suction inlet. 5. Upon hearing a coupling strike the ground, stop and visually check to ensure that the coupling is actually on the ground in the work area. If it is not, face the rear and take additional steps as necessary. 6. If the coupling is in the work area, dress the running line one time and drop the hose. 6/6 ENGINE EVOLUTIONS 5 Pulling a running line.03 PULLING FOLDS Used to place additional hose on the ground behind the apparatus.

NOTE The member should be 5' from any coupling to the rear and 10' from any coupling in front when standing on hose. -03. MODULES Engine company hose lays may be broken down into four distinct portions or modules. These modules, when put together in a specific sequence, will result in the type of hose lay required to abate the emergency. The four modules are: 1. Laying a 4" supply line with or without a 4 way valve. 2. Providing a 4" supply line. 3. Removing fire fighting lines. 4. Advancing fire fighting lines..01 MODULE I - LAYING A 4" SUPPLY LINE WITH OR WITHOUT A 4-WAY VALVE Laying a 4" supply line is used to provide a continuous supply of water from a fire hydrant to an engine apparatus at the fire (forward lay). If a single engine company is laying the line, a 4-way valve will be utilized on the hydrant. If a two-piece engine company is laying the line, the 4-way valve is not used. The line is laid without the 4-way valve to the hydrant. The 4" supply line is connected directly to the 200 Series engine (pump) spotted on the hydrant after sufficient hose is on the ground. Laying a 4" Supply Line with a 4-way valve (Single Engine): 1. The hydrant member rides in the jumpseat of the engine apparatus on the panel side (behind the Engineer), seat belt fastened. 6/6 ENGINE EVOLUTIONS 12 2. After the engine has stopped at the hydrant, the officer will give the command to "lay-a-line." Upon this command, the hydrant member will unfasten the seat belt and proceed to the rear of the apparatus. 3. The hydrant member will acquire the hydrant sling and place it over the arm and shoulder on the side opposite the hydrant. 4. While standing on the ground and facing forward, the hydrant member will grasp the handle of the 4- way valve with the hand on the hydrant side using a split grip. 5. The hand away from the hydrant, will be positioned behind the 4-way valve clear of the hose, grasping the nut in the web of the thumb and forefinger. (Also a natural grip.) 6. With both hands, the 4-way valve will be lifted clear of the bracket. Bend at the knees to remove 4-way valve from apparatus. 7. The hydrant member will pivot 180' toward the hydrant and place the 4-way valve well up on the hydrant side hip with bell reducer facing toward the rear. Laying a line Part-3 animated! NOTE If the 4-way valve is placed on the right hip, the 4" hose and coupling will be pointed down. If the 4-way valve is placed on the left hip, the hose and coupling will be pointed up. 8. After completing the pivot, the hydrant member will proceed away from the tailboard of the apparatus, removing sufficient hose to ensure being able to go around the hydrant to a point even with the officer or engineer (6 to 10 steps depending on the individual). Laying a line Part-4 animated! 9. When hose has been pulled to the rear of the apparatus, stop to ensure that sufficient hose has been provided to reach cab of apparatus. The hydrant member will pivot 180' toward the hydrant and proceed around the hydrant toward the driver or officer. NOTE Dip shoulder when making turn around hydrant. 6/6 ENGINE EVOLUTIONS 13 Laying a line Part-5 animated! 10. Stop, face the driver or officer, and signal the driver to "take off." 11. On the command "take off," the driver will begin moving the apparatus. The hydrant member will continue the hydrant operation when the apparatus stops or when two couplings have hit the ground. 12. At the proper time, the hydrant member will pivot into the 4-way valve placing it on the other hip and proceed back toward the hydrant, being careful not to walk in the folds, and positions self in front of the proper outlet. The hydrant member will then squat down in front of the outlet and place the 4-way valve down on the unused female inlet on its own hose. Laying a line Part-6 animated! 13. Keeping the 4-way valve secured between the knees, select the correct spanner to be used to remove the hydrant cap. With spanner hook away, remove the hydrant cap, check the hydrant threads and place all unused tools and equipment in the "V" formed by the hose around the hydrant. Laying a line Part-7 animated! 6/6 ENGINE EVOLUTIONS 14 Laying a line Part-8 animated! 14. Remove the 4" to 2 ½" reducer if necessary. NOTE To select the proper hydrant outlet when encountering a double hydrant, use the following criteria: a. Use the 2-1/2" outlet when encountering a 2-1/2" by 4" hydrant. b. Use the outlet pointing toward the fire when encountering a double 4" hydrant. 15. Grasp the 4-way valve using the split grip with one hand, stand up in front of the outlet, and make a gasket check with the other hand. The female inlet with the winged lugs will then be connected to the hydrant outlet. Laying a line Part-9 animated! 16. Check direction of flow handle to ensure that it is pointing in the direction of the supply line. 17. If the 4-way valve is attached to the hydrant, and it is noted that the hose is pointing away from the apparatus, tighten the female coupling on the 4- way valve only until the gasket starts to seat. Check the direction of flow handle. Turn the 4-way valve upside down to point hose toward the apparatus. Place slack hose on the ground, and tighten the connection. Laying a line Part-10 animated! 18. After the connection is made, proceed around the hydrant to the bight of hose. With the inside hand, grasp the end of the bight of hose with a proper hose grip, and proceed around the hydrant with the first of two "walks" used to clear the street of hose. 6/6 ENGINE EVOLUTIONS 15 As the hose becomes tight, stop forward motion, look back to see that the hose is not tangled, and drop the fold of hose. Step toward the hose in the street, grasp the hose once again with a proper grip and proceed with the second "walk" to clear the street of slack hose. As the hose becomes tight, stop forward motion, look back to ensure that the hose has not tangled, and drop the fold of hose. 19. Proceed to the side of the hydrant opposite the street (adjacent to the hydrant stem). Place the spanner on the correct hydrant stem in the proper position (handle to left with the tang away from the hand). Avoid standing directly in line with the hydrant stem. Laying a line Part-13 animated! Open the hydrant on the call for water. Hydrant tools and equipment, with the exception of the hydrant cap, are then carried to the apparatus and placed in a convenient compartment on the side opposite the fire. When returning to apparatus, member shall ensure that all kinks in hose are removed. Laying a 4" Supply Line without a 4-way valve: When the engine of a two-piece engine company is laying a line in conjunction with the 200 Series, it is not necessary to use the 4-way valve. The following methods can be used: 1. The hydrant member rides in the jumpseat of the engine apparatus behind the engineer, seat belt fastened. 2. After the apparatus has stopped, approximately 15' past the hydrant, the officer will give the command "Lay-a-Line." Upon this command, the hydrant member will unfasten the seat belt and proceed to the rear of the apparatus. 3. Place spanners and hose sling in rear compartment. 4. While standing on the ground and facing forward, the hydrant member will remove the 4" female coupling from the 4-way valve, ensuring that the 2-1/2" to 4" increaser remains on the 4-way valve. 5. Capturing the 4" female coupling with a two handed brass grip, hydrant member will pivot 180' towards the hydrant and place the coupling over the shoulder on the hydrant side. Assume proper hose grip between coupling and face. 6. After completing the pivot, the hydrant member will proceed to the rear of the apparatus, 10' to 12' past the hydrant. 7. When sufficient hose has been pulled to the rear of the apparatus, the hydrant member will pivot 180' towards the hydrant and proceed around the hydrant until the slack hose is tight against the hydrant base. 8. Hydrant member will remove the coupling from the shoulder and wrap the hose around the hydrant, pulling the line taut and grounding the coupling clear of the hydrant. 9. Hydrant member re-mounts the apparatus jumpseat, fastens seat belt and signals the engineer to proceed to the fire ("take off"). Alternate Method (using hose sling): NOTE 6/6 ENGINE EVOLUTIONS 16 This method is for two-piece engine company operations only. 1. Engine stops 25' in front of hydrant. 2. Engineer on 200 Series engine spots apparatus at the hydrant. 3. Hydrant member prepares to lay the line upon command of the officer. 4. Hydrant member goes to tailboard area of the engine and removes spanners placing them in the rear compartment. The hydrant member then disconnects the 4" hose from the 4-way valve, being sure to leave the 2-1/2" to 4" increaser on the 4-way valve. 5. Hydrant member places the 4" coupling on the hip towards the hydrant and then grasps the hose sling with the other hand. Hydrant member then pivots 180' towards the hydrant. This will place the 4" coupling and hose sling on the same side. 6. Hydrant member, with two hands on the coupling and the hose sling, will go around the hydrant and place the sling on the hydrant barrel or on the hydrant stem closest to the engine. The hydrant member will then lay the 4" coupling on the ground. 7. Hydrant member returns to the engine, gets in jumpseat and tells the engineer to "take off.".02 MODULE II - PROVIDING A 4" SUPPLY LINE There are two methods of providing a 4" supply line. The first, and by far the most frequently used, is the forward lay (hydrant to fire). The second method is the reverse lay (fire to hydrant). Forward Lay-(Hydrant to Fire): In a forward lay (hydrant to fire), it is necessary to complete the supply phase of the evolution prior to removing and advancing fire fighting lines. This involves pulling a running line on the 4" hose laid from the hydrant, breaking the line and connecting the 4" male hose coupling to the suction inlet on the panel side of the engine apparatus. 1. The engineer approaches the line laid from the panel side of the apparatus. 2. Stand on the ground, face to the rear, and grasp the 4" hose with a hose grip. 3. Proceed to the rear, always facing the direction of travel, until a coupling drops in the work area. 4. Check to determine that sufficient hose has been pulled to reach the suction inlet. Dress the running line. (Figure 26) 5. Return to the tailboard area and pull coupling within 3’ of tailboard. Break the 4" hose coupling. Bed the unused female coupling. 6. Shoulder the male coupling on the inside shoulder and proceed to the suction inlet on the panel side. (Figure 27) 7. Members may now begin the fire fighting phase of the hose evolution. 8. Make a gasket check and attach the 4" male hose coupling to the main suction inlet. (Figure 28) 9. Call for water. (Figure 29) Reverse Lay-(Fire to Hydrant): In a reverse lay (fire to hydrant), the fire fighting line is removed at the fire and connected to the 4" female coupling. With a member standing on the line, the engine apparatus proceeds to the hydrant, hooks up and pumps back to the fire fighting line. 1. Prior to the beginning of the fire fighting phase of the hose evolution, the hydrant member removes spanners from 4" hose bed and places in very rear compartment. Hydrant member then disconnects 4" coupling and 2-1/2" to 4" increaser from 4-way and places coupling on the ground adjacent to left side of tailboard area. 6/6 ENGINE EVOLUTIONS 17 2. As soon as practicable, nozzle member steps into work area after spanners are put away and breaks cross connect. Nozzle member then places coupling on shoulder towards the fire side and prepares to pull the first fold of a reverse lay. 3. Nozzle member pulls the first fold of a reverse lay. After hydrant member grounds the 4" coupling and is out of the work area, the nozzle member pulls the first fold of a reverse lay to the fire side. The nozzle member sets the coupling on the ground at the rear duals. 4. Nozzle member acquires proper nozzle and goes to rear duals on the fire side. 5. Nozzle member takes the coupling and attaches the nozzle, then sets the nozzle down. 6. Hydrant member, after grounding the 4" coupling, will prepare to pull folds from the proper side of the apparatus. 7. Hydrant member steps into work area to pull a fold, only after nozzle member goes past the tailboard with the first fold. 8. Nozzle member, after attaching the nozzle, shall proceed around the front of the apparatus and take a position on the proper side of the apparatus to pull folds. 9. After the proper number of folds have been pulled, the convenient member (nozzle member or hydrant member) will break the 2-1/2" coupling and come up with the female coupling. The member breaking the 2-1/2" coupling shall then bed the female coupling and dress the hose bed. 10. The nozzle member and hydrant member will get the proper fittings (the proper fittings can either be A, B or C: A. - 4-way valve - 2-1/2" double male - 2-1/2" gated wye - 2-1/2" to 1-1/2" reducer B. - 4" to 2-1/2" gated wye - 4" double male - 2-1/2" double female - 2-1/2" to 1-1/2" reducer C. - 2-1/2" gated wye - 2-1/2" double male - 2-1/2" double female - 2-1/2" to 1-1/2" reducer Working as a team, the nozzle member and the hydrant member will connect the 4" hose to the 2-1/2" hose using the proper fittings. 11. The nozzle member, after the connection is made, will shoulder the nozzle and prepare to take off. 12. Hydrant member will stand on the line and signal the engineer to "take off." The hydrant member will ground the loop away from the fire after two couplings have been grounded or the apparatus stops. 13. On the command to "take off," the engineer shall proceed with the apparatus to the hydrant. The engineer pulls a 4" running line to the fire side of the apparatus, breaks the coupling, beds the female coupling and connects the line to a discharge gate on the fire side of the apparatus NOTE The "reverse lay" method, when used by a single engine company, is far slower and less efficient than a "forward lay." Generally it is more effective to go past the fire, make a "U turn" and lay back to the fire with a "forward lay." Additionally, when using a "reverse lay," all required equipment shall be removed from the engine apparatus before sending it to the hydrant..03 MODULE III - REMOVING FIRE FIGHTING LINES Prior to advancing nozzles, couplings and hose to an objective; they must be properly, safely and efficiently removed from the apparatus, This module reflects the correct methods for removing 1", 1-1/2", 1-3/4" and 2-1/2" lines from an apparatus prior to advancing to an objective. Removing fire fighting lines is the second phase of "forward lays" (after providing a 4" supply line) and the first phase of a reverse lay" (before providing a 4" supply line). The methods used for removing fire fighting lines are the same, whether performing a "forward lay" or a "reverse lay." Removing 1", 1-1/2" and 1-3/4" lines: 6/6 ENGINE EVOLUTIONS 18 1. Approach the transverse hose bed from the fire side of the apparatus, mount the running board of the apparatus adjacent to the hose bed to be used. NOTE If the fire is at an angle to the front of the apparatus, use the front transverse hose bed. If the fire is at an angle to the rear of the apparatus, use the rear transverse hose bed. 2. Acquire the nozzle, shut it off and place it over the back of the right shoulder. Grasp the hose in front of and slightly below the right shoulder. Look over shoulder to ensure area is clear before stepping down from the running board. 3. Place the right hand and arm through the loop of hose extending from the hose bed. Recapture the hose leading over the right shoulder with the right hand. 4. Proceed directly away from the apparatus until a coupling is removed from the hose bed. When loop is clear, proceed toward objective. Removing 2-1/2" line (extension lay): 1. Grasp 2-1/2" nozzle from 2-1/2" hose bed. Place nozzle over right shoulder, position nozzle tip in small of back, and shut-off butt bale facing out. 2. Maintain hose grip on 2-1/2" hose with right hand. 3. With the other hand, grasp the hose, and when safe to do so, pull the hose away from the fire side. This will provide sufficient slack hose to reach the nozzle member.

Upon hearing a coupling strike the ground, stop and visually check to ensure that the coupling is actually in the work area. If the coupling has not exited the hose bed, then face the rear and take additional steps as necessary. 6. If the coupling is in the work area, pivot 180 degrees towards the fire side and proceed to the area adjacent to the rear duals on the fire side of the apparatus. 7. When safe to do so, approach the rear of the apparatus and position yourself on the side of the hose bed away from the fire (face the fire side). 8.

Pull additional folds until the required amount of hose has been removed from the apparatus. 6/6 ENGINE EVOLUTIONS 19.04 MODULE IV - ADVANCING FIRE FIGHTING LINES Advancing fire fighting lines includes all steps necessary to advance nozzles, hose and couplings to the objective. 1. Advancing of Nozzles: All nozzles shall be advanced with the nozzle placed over the back of the right shoulder. The right elbow is held high. The right hand maintains a hose grip on the hose just below and in front of the right shoulder. (Figure 33) 2. Advancing couplings: 2-1/2" hose couplings shall be advanced on the proper shoulder with the elbow held high. The coupling is in front of and below the shoulder. The hand maintains a hose grip on the hose between the coupling and the shoulder. (Figure 34) 1-1/2" and 1" couplings shall be advanced by carrying the coupling with a brass grip at arms length with the proper hand. The arm shall be straight. NOTE The "proper shoulder," as it applies to advancing 2-1/2"couplings, and the "proper hand," as it applies to advancing 1-1/2" and 1 " couplings, is that shoulder or hand that allows the member to advance the coupling to the nozzle without walking in the folds laid down previously. 3. Supply Side: In order for a hose evolution to be performed correctly, and in order to place hose couplings at an objective in a manner that facilitates advancement, it is necessary to designate to which side of a nozzle the couplings shall be placed. This shall be referred to as the supply side. Open Fires: To determine the supply side of a nozzle when encountering an open fire (any fire not in a structure), do the following: a. Draw an imaginary line perpendicular to and out from the fire side of the apparatus. b. Lay the couplings down on the side of the nozzle nearest the imaginary line. (Figures 37, 38 and 39) 2-1/2" HAND LINE – FOLDS METHOD OPEN FIRE To Hydrant To Hydrant 2-1/2" HAND LINE - EXTENSION LAY OPEN FIRE To Hydrant to Hydrant Fires inside a doorway: (Figure 40) 6/6 ENGINE EVOLUTIONS 20 To determine the correct placement of the nozzle and couplings when encountering a fire inside a doorway, do the following: a. Lay the nozzle down at the side of the doorway nearest the apparatus. b. Lay the couplings down, one after another, straight out from the center of the doorway. Proper placement of nozzles, hose, and couplings allows the line, once loaded to be advanced effectively and with a minimum of resistance. -04.
