    How about some more questions?
    How about going back and answering all of the questions I have asked in my other posts while I try to prepare some "good 'n' juicy" questions?

    I'm reposting these questions from a previous pages at the request of getting more questions:
    1) what is the difference between static and dynamic rope? which is used for rescue, and why?

    2) how long should you wait after cutting the battery on a car until you can assume an air bag won't deploy at a MVC?

    3) List all the equipment should you have with you if you are to be assigned to a fast team? for what reason are you listing each item?

    4) what tools do you need to breech a masonary/cinderblock wall? how about a sheetrock wall? what are the basic steps you use to breech the wall?

    5) how many windows should you open in order to effectively positive pressure a building?

    6) what should you always assume about fire walls?

    7) what tools should you (or your crew) be taking with you when you are conducting a search without a hoseline?

    and since Firefighter1219 seemed to have learned his lesson about asking stupid questions, here are some of the better ones that he posted that didn't get responses too:

    If you have a reverse lay going to a fire, and you are holding a hose at the fire, which coupling do you have on your hand?

    When hooking into a fire department connection with only one line, which side do you hook in to?

    You are working off of a ladder with a pike pole on the right side, which side do you lock in on?

    Which end of a haligan is the adze end?

    Which side of the window is the windward side?

    If possible backsdraft conditions are found to exist, what should be done to correct the problem?

    If the main valve on your airpack malfunctions and you can't get air, what can you do while you and your partner are leaving the IDLH area?

    While conducting an interior search, what does an X on the door mean?

    You're on a RIT team and are activated to rescue an interior team. You find a chalked / on a door. What does it mean?

    What should you do to a hydrant before you hook into it for water supply?

    2) how long should you wait after cutting the battery on a car until you can assume an air bag won't deploy at a MVC?
    - I dont belive that you CAN assume that the AB wont go off. thats why you should always wear your helmet while @ MVCs

    3) List all the equipment should you have with you if you are to be assigned to a fast team? for what reason are you listing each item?

    Hoseline-to put out any fire and to cover teammates whilst making rescue
    Set of Irons-to get where you need to go
    Chainsaw- to move/cut anyobject that impedes rescue
    Spare SCBA unit- to give to downed FF in case his is damaged/OOS
    rope- in case of need to bailout

    4) what tools do you need to breech a masonary/cinderblock wall? how about a sheetrock wall? what are the basic steps you use to breech the wall?
    Mas/Cind wall- flathead axe/slegehammer, and a breaching pike.
    Sheetrock- roofhook

    7) what tools should you (or your crew) be taking with you when you are conducting a search without a hoseline?
    -Irons, and hoseline

    Which end of a haligan is the adze end?
    -the pointy end

    Which side of the window is the windward side?
    -facing AWAY from the wind

    If possible backsdraft conditions are found to exist, what should be done to correct the problem?
    - have the Ladder Co. vent the roof, thus releasing he gasses with out causing a backdraft

    2) yes and no. there are actually books that say how long you need to wait before an airbag is deactivated. but your right, always assume that an air is active, spend as little time as you can in front of it, and always wear your gear (includes coat, helmet, eye protection, etc)

    3) in all honesty, I've never seen a fast team with a dedicated hoseline (when they weren't activated anyway). good stuff, but you need a few more things. remember, you need to have all the equipment for any situation, and you won't just might not use it if activated

    4) correct, however to breech a sheet rock wall, in an emergency, an ax or haligan can be used.

    5) what if you are assigned to do a search without a hose line? btw, there are other tools besides the irons that you can take.

    correct on the other ones though :-)

    Which end is that? I was looking for another answer.

    answers to the questions I posted

    1) static rope doesn't stretch when tension is applied. dynamic rope does. as a result, only static rope is used in rescue operations.

    3) while much of this is personal preference, I would add a set of bolt cutters, and a maul/sledge in case you needed to breech a masonary wall to gain entry into a building

    5) only one. if you open (or break) more than one, it won't work effectively.

    6) always assume they will fail, as they probably have holes cut in them by cable guys, contractors, electricians, etc.

    7) a closet hook might be a good thing to bring, as well as a water can.

    Here is a hydraulics problem - but not for those “faint of heart”, only those who like a challenge. This is more of a test to see who really understands hydraulics.

    1) A hydrant (“H”) has one 4-1/2" outlet and one 2-1/2" outlet.
    2) To the 4-1/2" hydrant outlet is attached 500 ft of 5" LDH, that supplies Engine (E-1).
    3) To the 2-1/2" hydrant outlet is attached 1000 ft of 2-1/2" hose supplying E-1.
    4) E-1 is a standard 1,500 gpm pumper.
    5) E-1 supplies 300 ft of 2-1/2" hose to a wye.
    6) One side of the wye supplies 100 ft of 1-3/4" hose to which is attached a 1-1/8" smooth bore nozzle.
    7) The other side of the wye supplies 250 ft of 1-1/2" hose to which is attached a 1" smooth bore nozzle.
    8) The pump discharge pressure (PDP) is 250 psi.

    Assumptions:
    A) There is no friction loss in the wye. This will make it a bit more simple.
    B) Ignore the pressure loss in the steel piping inside the engine. Assume the PDP is at the point where the 2-1/2" hose is attached to the discharge outlet of E-1. Again, this is to simplify the problem.
    C) Ignore the “rule of thumb” that the nozzle diameter should be no larger than ˝ of the hose diameter.
    D) Both nozzles are fully open.
    E) Use the hose friction loss coefficients that are commonly found in hydraulics textbooks.

    1-1/2" = 24
    1-3/4" = 15.5
    2-1/2" = 2
    5" = 0.08

    Questions:
    1) How much water (gpm) is E-1 pumping?
    2) How much water (gpm) is discharging from the 1" tip?
    3) How much water (gpm) is flowing in the 5" LDH?

    Hints and conditions:
    1) The problem IS solvable with the information provided. No additional information is needed.
    2) Guessing and trial and error solutions are not acceptable.

    Good Luck and Have fun.

    Oh Yeah, Happy New Year!!!!!!!!

    Ok, I'm trying this one out and I'm ending up with more friction loss than the PDP. Are you using 50 PSI as the NP?

    So far so good. You need to differentiate between REQUIRED PDP and ACTUAL PDP. Visualize this layout with the nozzles discharging water. You walk up to the pump panel and see a PDP of 250 psi. What are the flow rates?

    In other words, it doesn't matter what PDP is required. However, you do need to calculate the required PDP to solve the problem.

    Keep going. What required PDP did you get?

    Default HOLD IT!

    OK, I found a part of my problem. Somehow I ended up with a number which was WAY off. I think my fire calc's on crack. It keeps getting weird on me. (CP throws calc across room - searches for paper)

    I have REQUIRED pdp @ 320psi. (seems kinda high)

    The flow rate of the 1" is 210gpm. (assuming NP is 50)

    I'll get back to you on the LDH part.

    Yes, the 1" nozzle will flow 210 gpm IF the NP is 50 psi. How did you get 320 psi required PDP?

    Don't be concerned about the high required pressures. Remember, the pump is actually dicharging at 250 psi.

    HINT: When you successfully calculate the required PDP, it will a lot higher than 320 psi.

    If the main valve on your airpack malfunctions and you can't get air, what can you do while you and your partner are leaving the IDLH area?

    These questions are subjective and have no "right answer". Each one can be answered a myriad of ways and it would depend on your department equipment, policies and a ton of other factors.

    Thumbs up wow....

    This is a great thread! I am learning lots!, now I only wish there was a Jr./Explorer program in my town when I was growing up, as I feel dumb now..lol.

    Anyways, keep up with the questions!...and the answers for those who have no clue...like me!
