    Default Who's the smartest Jr./Explorer

    I will post you guys a question from time to time. Some will be easier than others.

    1. Name the 4 traditional classes of fire and give an example of each.

    Default good idea

    this is a good idea.

    class A(common combustibles such as paper, wood, plastic, or rubber)
    example: a brush fire
    class B(liquified gas)
    example: gas, diesel, or kerosene fires
    class C(charged electrical fires)
    example: a toaster fire(provided the toater is pulgged in. unplug it and you have a class A fire.)
    class D(metal fires)
    example: magnesium fire

    class A: water, class A foam(wet water), dry chem extinguisher
    class B: class B foam, dry chem extinguisher
    class C: dry chem extinguisher or de-energize and use extinguishing agent for appropriate class of fire.
    class D: various dry powder depending on type of metal involved.

    I may not have been here to answer #'s 1 and 2, but the answer to #3 is...
    Water is used as a cooling agent, and the fire triangle consists of heat, fuel, oxygen, and a chemical reaction to combine all 3. Remove the heat by putting water on the fire, cooling it off, and voila, fire is out, because all 4 elements are needed to support combustion.
    These are my opinions, not those of my career department, my volunteer company, or my affiliates. And by the way, I'm not a Junior.

    IACOJ is the International Association of Crusty Old Jakes.

    IACOJ Explorer's are a division of Explorer's within the IACOJ. There is also an EMS Division, and the BMI.

    The Explorer division, has recently started a mentoring program. Where IACOJ Explorer's are assigned a mentor to bounce things off of. Some of the the Explorer's are already firefighters, while others are Jr's/Explorer's.

    Hope that answers your questions. If you have more please feel free to email or pm me.

    What in water puts out a fire?

    What does a class 'C' fire become when it is deenergized?

    What is the difference between exothermic & endothermic reactions, and what is an example of each?

    Finally...What is pyrolysis?



    WFDjr...good job...you described the fire tetrahedron.

    Default Class D Fires

    FireExplorer13,
    Excellent answers about class D fires. Let's turn to a practical application question. If you have a class D fire and no class D extinguisher, what can you use to put the fire out?

    Correct on the hazmat question.

    5. Define what is a class K fire, and what extinguishing agent is used.

    What does a class 'C' fire become when it is deenergized?
    Class A

    What is the difference between exothermic & endothermic reactions, and what is an example of each?
    Exothermic is when a chemical gives of heat- concrete cureing
    Endothermic(just guessing on this-i dont know everything)when something gives of cold. Portable ice packs?????

    Finally...What is pyrolysis?
    When the flame is "above" the fuel, not sure of the technical reason.

    If you have a class D fire and no class D extinguisher, what can you use to put the fire out?
    Sand.

    And on the water one- doesnt it also stop the unrestricted chemical reaction?

    Can someone name the 4 fire classes shapes and colors??


    I dont know it all,I just want to learn.

    Class 'K' Fires...

    The "K" is for Kitchen, or more commonly, what is in them. Cooking oil and cooking oil appliance fires are class K fires. To extinguish them, you need a wet potassium acetate basedagent that has a greater fire fighting and cooling effect than a class B extinguisher.

    "When the flame is "above" the fuel, not sure of the technical reason..."

    We were watching a video on propane fires a few weeks back, and it contained something about this. I think it was because the vapor density down low was too high to support combustion, and after it dispersed a little bit, it would ignite, thus making the flame appear above the product. Correct me if I am wrong, but I'm pretty sure that's what it is.

    Tempie, while I am thinking about it, can you pair me up with a mentor as well?

    Ummm........er......


    Shoot.

    If there's an award for "Explorer who knows the absolute LEAST about the science and mechanics of firefighting, as obviated by the number of questions in this thread that he has no idea about" I'll take it and go hide somewhere.

    Oops.

    Didn't notice till now that htis is in the ACTUAL Explorer's area (all I did was follow Temptaker's link). I ASSumed that this was still the Off-Duty area.

    Sorry for intruding.

    Anyone know what is wrong with this statement?


    1) Chemical Reaction is NOT part of the fire triangle. A triangle only has 3 sides. The Fire Triangle is just Heat, Fuel, and Oxygen.

    2) Heat, Fuel, Oxygen, and Chemical Reaction make up the Fire Tetrahedron.


    Surprised I didn't see anyone pick up on that.
