SCUBA SUPERVISOR ACTUAL EXAM
QUESTIONS WITH VERIFIED ANSWERS
What chapter in the U.S. Navy Diving Manual is SCUBA Air Diving Operations discussed?
Chapter 7
What is the normal working limit for open circuit SCUBA?
130 fsw
What is the maximum working limit for open circuit SCUBA?
190 fsw
Name some OSHA restrictions for DoD divers.
1.) SCUBA max depth = 130fsw.
2.) Level 1 chamber required for dives deep than 100fsw.
3.) Must had a manual reserve (j-valve).
4.) Must have SPG.
(ref. 7-2)
List the minimum equipment requirements for a SCUBA dive.
1.) open-circuit SCUBA with submersible pressure gauge, 2.) buoyancy compensator, 3.) weight,
4.) dive knife, 5.) face mask, 6.) swim fins, 7.) submersible wrist watch, 8.) depth gauge, 9.)
octopus
What is the minimum manning levels for open circuit SCUBA diving?
What is the single greatest safety practice in Navy SCUBA operations?
use of the buddy system
What items of the minimum SCUBA equipment are not necessary for pool phase of
SCUBA training?
1). knife
2.) SPG
3.) submersible wrist watch
4.) depth gauge
True or False:
An octopus is mandatory for standby diver.
True.
When diving without a reserve, the dive shall be terminated when the cylinder pressure
reaches _____ PSI for a single cylinder or_____ PSI for twin manifold cylinders.
, 500psi for single / 250psi for twins
What is the periodicity for a SCUBA cylinder to be:
1.) visually inspected (VIP)
2.) hydrostatically tested
??
VIP = annual
Hydro = 60M/ every 5 years
What is the minimum size SCUBA cylinder authorized as a primary air source?
50 cubic feet / the aluminum 50
j-valve vs. k-valve?
J-valve: employs a built in air reserve mechanism
K-valve: no reserve
When charging a cylinder with a j-valve, in what position should the reserve be in?
the reserve lever must be turned down (check valve open) to charge the cylinder.
Are BCs required when using a VVDS?
No.
what are the three basic types of lifelines?
1.) tending line
2.) float line
3.) buddy line
when is a tending line required?
1.) required for standby diver and single divers.
2.) required when direct access to the surface is not available.
when may a float line be used and what are the requirements?
May be used instead of a tending line only when direct access to the surface is available. The
surface float should be no smaller than an 11 inch inflatable buoy, or similar, and be brightly
colored to be easily visible in open seas (international orange is recommended).
What is the typical length of a buddy line?
6 to 10 feet
Understand the calculation for duration of air supply.
