Who's the smartest Jr./Explorer

[SPIPER]

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.

[FF_Engine04]

Smartest??? There is no "smartest" Explorer/Jr.

[SPIPER]

Now we don't have to go and start bashing the kids. They are still learning.

[FireExplorer13]

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

[SPIPER]

2. Name an extinguishing agent for each class of fire.

[FireExplorer13]

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.

3. Explain how water suppresses fire in relation to the fire triangle.

Great idea!

Explorer's/Junior's

If any of you have not at this point either applied to the IACOJ Explorer's and would like to, or if you have and would like a mentor, please email or pm me, and I will find someone for you.

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.

[SPIPER]

Using water as an extinguishing agent to suppress fire by removing the heat, oxygen, or both.

4. What are the 9 hazard classes as defined by the D.O.T.?

[WFDjr1]

Explosives, Compressed Gases, Combustible Liquids, Combustible Solids, Oxidizers, Poisons, Radioactives, Corrosives, and Miscellaneous

What is IACOJ?
I am confused about this can someone please explain..

What are the IACOJ Explorer's ?

[Temptaker]

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.

[Ohiovolffemtp]

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?

[SPIPER]

Correct on the hazmat question.

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

[dfdex1]

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.
