C, D, A, It is always about the best answer.
C firefighters on air should always be working in pairs
D when disoriented a firefighter should attempt all of the above.
A Accountability on scene is of paramount importance.
I'm with majority here...C,D,A.
The second question threw me though. I was thinking "C", even after reading all the replies. Then I re-read the question and it did not state a timeline. So yes, a firefightewr should do all the above in the order shown: A then B then C.
But then again... is the "origional location" the place when you realized you were lost? Or is it when you entered the building? Could it be when you reported to accountability? Or how about when you left the house?
I'll still go with C,D,A.
1. - C) is correct. A) is something that you NEVER do, and B) is not necessarily where the IDLH atmosphere will be.
D) is a little trickier, but since lifelines are not required if you're on a hoseline, it is an incomplete answer.
2. - D) is the most correct, but this is misleading. If you're lost in cold smoke in a big box fire, both A) and C) are the correct actions. You should not try B) in that situation, because you'll waste your SCBA air and you're probably low already. On the other hand, if you can find a wall, a window, or a staircase in a single-family residence fire, then B) may get you quick help or even a safe exit from the structure. Like my Question 2 in the Two-Question Test thread, the missing element to this question is CONTEXT.
3. - The best answer is A) because that is the intent of a Personnel Accountability System. A Personal Alert B) and PASS D) are essentially the same thing, and are used only in case of a MAYDAY call or unconscious/disabled firefighter. C) is not a common or nationally-accepted term in the fire service. It is listed nowhere in IFSTA, J&B, NFPA, or NIMS terminology, as far as I'm aware. This one goes in the "weak confuser" category.
OK, I just answered before, but I now think I should have explained my answers like some others did.
1-C, This is right out of the OSHA standard. Always work in pairs, although constant physical contact is not required.
2-A, First lets look at why not the other answers, because that make this one obvious. It would be impossible to both seek an area of refuse and retrace your steps to your original location, unless your original location is an area of refuge. In that case you probably wouldn't be disoriented in the first place. Now since B & C are mutually exclusive, that eliminates D as an option. That only leaves one answer, A: REMAIN CALM, which by the way should be a prerequesite for any of the other options.
3 - A, This is really the only answer that makes sense in the sentence. although without the spelling error I guess C could be the right answer worded slightly wrong.
