When can a sports diver dive with an ocean diver or another sports diver? - ANSWER
In conditions already encountered by the ocean diver during their training and under the
supervision of a dive manager.
What's the initial limited depth for a sports diver? - ANSWER 20m
What's the progressively extended depth of a sports diver? - ANSWER 35m
Is a neap tide small or large? - ANSWER Small
Is a spring tide small or large? - ANSWER Large
What causes a neap tide? - ANSWER When the Moon is at a right angle to Earth and
the Sun, creating the least amount of gravitational pull in one direction, creating weak
tides.
What causes spring tides? - ANSWER The gravity of the sun and moon pull in the same
direction, creating strong tides.
Neap tides coincide with what? - ANSWER The quarters of the moon
Spring tides coincide with what? - ANSWER New and full moon
What's the average tide cycle in most places? - ANSWER 12 hours
How many tide cycles in a day? - ANSWER 2
How many high tides in a day? - ANSWER 2
How many low tides are there in a day? - ANSWER 2
How many times do spring tides occur in a lunar month? - ANSWER 2
How many times do neap tides occur in a lunar month? - ANSWER 2
What's the tidal range? - ANSWER High water - low water
What's slack water? - ANSWER At the tides turning point, when the water speed is at its
slowest.
, What can make diving on a static site (e.g. a wreck) safer? - ANSWER Diving in slack
water
What is ground swell? - ANSWER When wind causing wave action on the surface can
be felt on the sea bed.
When is ground swell the roughest? - ANSWER When the surface winds go against the
tide/stream/current flow.
Is an incoming or outgoing tide better for visibility? - ANSWER Incoming
What are five factors that can affect visibility? - ANSWER - bad weather
- tides
- being close to river estuaries
- lots of phytoplankton + zooplankton (most likely to be a problem in spring in most
places.)
-disturbance by divers.
What are the four things to check for under the response section of DRABCD? -
ANSWER A alert
V response to voice
P response to pain
U unresponsive
How long should you check for breathing before determining a casualty is not
breathing? - ANSWER 10 seconds
What's the BLS sequence? - ANSWER 30 chest compressions followed by 2 breaths
What does AED stand for? - ANSWER automated external defibrillator
How often should you switch CPR if there's more than one rescuer? - ANSWER Every 2
minutes
What does CC stand for? - ANSWER Chest compressions
Why must an oxygen administration kit be removed from a casualty before an AED
shock? - ANSWER Risk electric shock will cause the oxygen to combust
At what rate should chest compressions be given? - ANSWER 100-120 bpm, remember
to stop every 30 to admin get two rescue breaths
When doing CC, when should you stop to check breathing? - ANSWER Only if it has
obviously returned to normal, otherwise don't stop CPR until help arrives.
