Your regulator consists of five components. The first degree is the "hub" of your regulator and
substances air to the additives - the second one stage, alternate air source, low strain inflator
hose and SPG/dive computer.
See Equipment I - Regulators. - ANS-12) Refer to the regulator photograph. Each regulator part
has a number of subsequent to it. Please pick the suitable range for the selections under.

A Ascend (move up) proper away to 5 meters and live there for at least 8 minutes earlier than
going to the floor, and not dive for 6 hours.
Using RDP Table 1, discover the subsequent best depth at the pinnacle row - 18m - and
observe the column all the way down to the time or subsequent finest time - forty eight/forty
seven - pass across the find strain organization S.
In RDP Table 2, comply with S to locate 30 minutes (between 28-32 minutes) and follow that
column all the way down to strain group L.
Go to RDP Table three, observe the following greatest intensity - 18m - across to fulfill L. The
range in the blue box - 24 - is permitted backside time.
Staying 25 mins method you have overstayed your bottom time through one minute. The rule is
to ascend to five meters and live there for at the least eight minutes before going to the surface,
and no longer dive for six hours.
See the RDP/eRDPML Instructions for Use book. - ANS-53) I dive to 17 meters for forty seven
mins. After a 30-minute floor interval, I do a second dive to 17 meters. Losing music of time, I
note my bottom time is now 25 mins.
,According to the General Rules, what need to I do?
Note: you could must scroll right down to see the whole question or to publish your solution.
A Ascend (go up) proper away to five meters and live there for as a minimum 8 minutes before
going to the floor, and no longer dive for 6 hours.
B Go to the floor right away and call the nearest recompression chamber.
C Ascend (move up) proper away to 5 meters and live there for 3 minutes before going to the
surface.
D Ascend (move up) to a few meters and stay there until I dissipate my air, and now not dive for
twenty-four hours.
A Ascend (move up) to a shallower intensity.
If you or a buddy revel in narcosis, immediately ascend to a shallower intensity. Narcosis
commonly fades speedy whilst you return to a shallower intensity.
See Being a Diver V - Gas Narcosis. - ANS-38) Divers who act foolishly at depth because of fuel
narcosis may begin acting commonly again if they
A ascend (move up) to a shallower intensity.
B breathe slowly and deeply.
C signal their pal for help.
D dive inside no prevent limits.
A ascend (pass up), make a protection stop and cease the dive.
The system for a failed dive laptop is to sign your buddy, ascend, make a protection stop and
stop the dive. If you're closing well within limits throughout the dive, you need to floor inside
established limits. You cannot preserve to dive with out being able to music your dive profile.
See Using Dive Computers and Tables I - Diving with Your Computer. - ANS-forty seven) If my
pc fails all through a dive, I can use my backup computer to preserve the dive. If I'm no longer
sporting a backup, I must
A ascend (go up), make a protection forestall and end the dive.
B borrow my buddy's backup.
C keep the dive until low on air, however make no repetitive dives.
D stop the dive and floor right away.
A Ascend the use of my buddy's exchange air supply / make a controlled emergency swimming
ascent
, You could make a ordinary ascent when very low on air, but your cylinder isn't absolutely empty.
When out of air, your nice option is typically to make an trade air supply ascent the usage of
your pal's change air supply. Make a managed emergency swimming ascent when pretty
shallow and the floor is nearer than a friend with an alternate air supply. Make a buoyant
emergency ascent when your pal isn't always close to and you're deep sufficient which you do
not assume you may make it to the surface via simply swimming.
See Being a Diver III - Underwater Problem Management. - ANS-35) Although it should not
have came about, on a dive I fail to look at my SPG and run out of air. If my friend is close by,
my fine choice is to __________. Another alternative is to _____________, if I'm in shallow
water and the floor is nearer than my buddy.

A ascend the usage of my pal's alternate air source / make a controlled emergency swimming

B ascend the usage of my pal's change air supply / make an buoyant emergency ascent
C make a regular ascent / ascend the usage of my buddy's exchange air supply
D make a controlled emergency swimming ascent / make a ordinary ascent
A become half the scale it become at the surface.
At 10 meters, the pressure is 2 bar. An air volume taken to this depth from the surface would
decrease and turn out to be 1/2 the size.
See Being a Diver I - Water Pressure and Air Volume Effects. - ANS-3) I turn a glass the wrong
way up, lure the air in it by using setting it in water, and then I take the glass down to 10 meters.
The air area could
A grow to be half the scale it become at the surface.
B now not alternate in length.
C become 1/3 the scale it was on the surface.
D turn out to be 2/three the dimensions it become on the surface.
A Compress (feel thinner) from water stress, and I will lose buoyancy and heat.
The small bubbles on your moist fit compress as you get deeper. This reasons your buoyancy to
lower and makes the moist fit thinner, which influences warmth. To control your buoyancy, add
small amounts of air to your BCD often throughout descent.
See Being a Diver II - Descents in Open Water. - ANS-17) As I descend (go down), my wet
healthy will
A compress (sense thinner) from water pressure, and I will lose buoyancy and heat.
B increase (sense thicker) from water stress, and I will advantage buoyancy and heat.
