Parent O2 Tank Assembly and Disassembly

This quiz is designed to test your knowledge of oxygen tank operation. Read each question fully and make sure you understand what the question is asking before you answer. Some questions are select all that apply, these will be marked by square check boxes. After answering all questions to the best of your ability, click the “Submit” button at the bottom of the page. Your score will be shown at the bottom of the page after submission. You may reset this quiz as many times as you would like.

1 An oxygen tank can be left standing while you go to get a regulator.

True.
False.

2 You have placed the regulator on the oxygen tank and hear hissing. What should you do first?

Leave the tank alone, this is normal and will stop after 15-30 seconds.
Recheck the O-ring and the seating.
Tighten the connection.
Open the tank fully then close it back off.

3 An oxygen tank typically contains what percentage of oxygen?

25%, slightly more than normal air.
50%, 2.5 times more than normal air.
75%, 3.5 times more than normal air.
100%, almost 5 times more than normal air.

4 You have performed a crew exchange and note that your main oxygen cylinder (D tank) on the is reading at 400 psi. After verifying that the tank is, in fact, on what should you do?

Leave the tank as is.
Refill the tank from another, larger cylinder.
Switch out the tank and remove it from service.
None of the above.

5 You note that your oxygen tank regulator has a dry, cracked O-ring that is causing an air leak. The regulator must be removed from service.

True.
False.

6 You have started your shift and were told that the off-going crew ran several respiratory distress calls. During your rig checkout, you note that the main oxygen tank (M tank) is at 2,000 psi. You know that this means the tank is

Full.
Mostly full.
Halfway full.
Almost empty.

7 A normal car tire pressure reading is 32-35 psi. A full portable oxygen tank at 2,000 psi is around 60 times more pressurized than the tire that holds several thousand pounds of vehicle off the ground. An accidental expulsion of this pressure from a severely damaged oxygen tank can be catastrophically damaging and all care should be taken to prevent these accidents.

True.
False.

8 You are disassembling your oxygen tank to replace it after a series of critical calls. You are attempting to bleed the pressure and have set the flow rate valve to the maximum. You have been waiting several seconds and have noted no change in the tank's pressure gauge. What is the most likely cause?

This is normal, as the pressure equalizes with the external pressure the gauge will remain in place.
The pressure in the tank is not changing.
You have forgotten to turn off the tank.
None of the above.

9 Oxygen tanks are opened by turning the valve to the

Right/Clockwise.
Left/Counterclockwise.

10 You may release the oxygen tank from your hand once it has been fully secured to the gurney or designated oxygen tank storage area.

True.
False.
