QUESTIONS WITH ANSWERS TAGGED A+
✔✔How do you prepare new fins for use? - ✔✔full foot- no preparation
adjustable strap- need to adjust
✔✔What 3 considerations do you have when buying a specific type of fin? - ✔✔size
physical ability
where you plan to dive
✔✔Why does a diver need a BCD? - ✔✔allows you to regulate your buoyancy
underwater
provides positive buoyancy for resting
✔✔Why do divers need a back pack? - ✔✔to hold the cylinder
✔✔Of the 3 styles of BCD, which is the most commonly used by recreational divers? -
✔✔jacket style
✔✔What 5 features do BCDs have in common? - ✔✔1) enough air
2) large diameter inflation/deflation hose
3) low pressure inflation system
4) over pressure relief valve
5) adjustable to fit comfortably
✔✔How do you prepare a BCD for use? - ✔✔adjustment for proper fit is required
With it deflated, adjust the straps
Put it on, have someone help fine tune it
Inflate it
✔✔What additional maintenance requirements do you have with a BCD? - ✔✔rinse
interior with fresh water
store partially inflated
✔✔Why does a diver need a scuba cylinder? - ✔✔used to safely store high pressure air
✔✔What does a cylinder valve do? - ✔✔control air flow from the cylinder
✔✔With what piece of equipment is the backpack integrated? - ✔✔cylinder
✔✔What are 4 common sizes and 2 materials for scuba cylinders? - ✔✔8, 10, 12, 15
liters
aluminum and steel
, ✔✔What 5 common markings do you commonly find on the neck of a scuba cylinder? -
✔✔1) type of material cylinder is made of
2) max pressure permitted in cylinder
3) serial number
4) dates of pressure tests
5) manufacturer symbol
✔✔What are 2 basic types of cylinder valves? - ✔✔K-valve: simple on and off
J-valve: built in mechanism that signals when you run low on air
✔✔What's the difference between a DIN valve and a Yoke valve? - ✔✔DIN: screw the
regulator into the valve
Yoke: most common, attach regulator via Yoke
✔✔What is the purpose of a burst disc? - ✔✔relieve the cylinder over pressurization
which can happen from overfilling the cylinder or excess heat
✔✔How do you turn a cylinder valve on and off? - ✔✔Open slowly until it stops turning
Close it all the way gently
✔✔What's the best way to keep water out of a scuba cylinder? - ✔✔never allow it to be
completely empty
✔✔Why do you need scuba cylinder visual inspections and pressure tests? -
✔✔overfilling can lead to metal fatigue and shorten the life of the cylinder
to avoid corrosion
✔✔What does a regulator do? - ✔✔- makes it possible to use the air to your cylinder
- reduces scuba cylinder's high pressure air to match the surrounding water pressure
✔✔When looking at a regulator, which are the following parts:
first stage - ✔✔first stage: attach to scuba cylinder valve
second stage: has a mouthpiece
✔✔What's the most important feature for consideration when purchasing a regulator? -
✔✔ease of breathing
✔✔How do you rinse a regulator after use? - ✔✔soak it, while attached to your scuba
cylinder
then rinse with running water
✔✔What 3 points do you need to keep in mind when rinsing your regulator? - ✔✔1)put
the first stage dust cover firmly in place to keep H2o out of first stage
2) Do not use high pressure water to rinse
