✔✔Wind can affect dive conditions in which of the following ways? (Choose all that
apply.)
1. Cause currents
2. Cause upwelling that affects water temperature and visibility
3. Generate waves and surge
4. Prevent overheating at the surface - ✔✔1. Cause currents
2. Cause upwelling that affects water temperature and visibility
3. Generate waves and surge
Wind can cause waves, surf, surge and surface currents plus poor visibility. Offshore
wind can calm surf and cause an upwelling and good visibility.
✔✔The primary reason for having and using accounting procedures is to be sure every
diver returns from the dive. Incident reports indicate that problems with this usually
result from:
1. using an inaccurate accounting procedure.
2. divers refusing to participate in roll calls.
3. failure to use an accounting procedure at all. - ✔✔3. failure to use an accounting
procedure at all.
Incident reports indicate that in the few cases where divers have been left behind, the
likely cause isn't faulty accounting procedures, but rather failure to use a procedure.
✔✔Which of the following are examples of responsible diver behavior? (Choose all that
apply):
1. Planning dives within the limits of training and experience.
2. Diving regularly to the maximum depth and air supply limits.
3. Having the proper equipment for the dive and making sure it is working properly
before getting in the water.
4. Taking care to avoid contact with sensitive aquatic life and respecting the underwater
environment. - ✔✔1. Planning dives within the limits of training and experience.
3. Having the proper equipment for the dive and making sure it is working properly
before getting in the water.
4. Taking care to avoid contact with sensitive aquatic life and respecting the underwater
environment.
A diver displaying responsible behavior will stay within personal limits and plan dives
within limits of training; use equipment required for a dive, maintain it properly, and
check it before diving; check air supply frequently; stay well within no decompression
,limits and avoid contact with aquatic life while diving in an environmentally sensitive
manner.
✔✔What are ways you can encourage responsible diver behavior? (Choose all that
apply):
1. Be a good role-model
2. Remind divers of responsible behavior
3. Ignore divers who conduct themselves irresponsibly
4. Make responsible behavior easier logistically - ✔✔1. Be a good role-model
2. Remind divers of responsible behavior
4. Make responsible behavior easier logistically
To encourage responsible behavior, be a good role model, suggest or remind divers of
responsible behaviors, make responsible behaviors easier logistically, and reward
responsible behavior by acknowledging divers.
✔✔Paying attention to a diver's ______________ may help you assess for
apprehension or stress related to the dive.
1. equipment
2. log book
3. behavior - ✔✔3. behavior
A behavioral change is a sign of predive stress.
✔✔Signs and symptoms of psychological stress include (choose all that apply):
1. being uncharacteristically withdrawn.
2. talkativeness.
3. irritability.
4. distraction.
5. perceptual narrowing. - ✔✔All of the above.
Signs of symptoms of diver stress include becoming withdrawn, irritable, overtly
talkative or distracted, along with perceptual narrowing.
✔✔Before a dive along a wall that drops into extremely deep water, you notice a diver
seems preoccupied and withdrawn. You talk to the diver and learn the person doesn't
feel adequately skilled with buoyancy control and fears descending out of control. What
could you do to help the diver with this predive stress?
1. Review buoyancy control and guide the diver to a part of the site that is away from
deep water.
2. Have the diver reduce the amount of weight worn for this dive.
,3. Advise the diver not to make the dive. - ✔✔Stress is relieved by either removing the
stressor or changing the diver's perception of the stressor so it's no longer threatening.
✔✔Aspects of effectively supervising and managing dives for certified divers include
(choose all that apply)
1. adequate dive planning.
2. having a good vantage point.
3. communicating clearly with divers.
4. recognizing, anticipating and identifying possible problems. - ✔✔All of the above.
The four aspects of supervision in managing dives include adequate dive planning,
communicating clearly with divers, having a good vantage point, and recognizing,
anticipating and identifying possible problems.
✔✔What types of equipment can assist in supervising certified divers? (Choose all that
apply):
1. Emergency response equipment - rescue float or life ring, emergency oxygen, first
aid kit, marine radio or mobile phone, etc.
2. Spare equipment - o-rings, mask straps, extra BCD, etc.
3. Management equipment - dive roster, binoculars, clip board, etc. - ✔✔All of the
above.
To assist you in keeping track of and assisting divers, have management equipment,
emergency response equipment, a tool kit with spare parts and spare equipment.
✔✔Which of the following is an advantage to inwater supervision?
1. You are close to divers to respond to or prevent problems.
2. You are close to emergency-related equipment.
3. You can give buddy teams more individual options. - ✔✔1. You are close to divers to
respond to or prevent problems.
The advantages of inwater supervision include being close to divers to respond to or
prevent problems, along with adding to the dive by guiding divers to interesting areas
and pointing out local aquatic life.
✔✔Which of the following is a disadvantage of out of water supervision?
1. You can only watch one group at a time.
2. You limit each buddy teams ability to explore independently.
3. You can't remind divers to follow dive procedures. - ✔✔3. You can't remind divers to
follow dive procedures.
, The disadvantages of out of water supervision include not being able to remind divers of
their responsibilities to follow appropriate dive procedures, and you can't show divers
the site's points of interest.
✔✔In general, a dive briefing should include (choose all that apply):
1. an environmental orientation.
2. entry and exit techniques along with other dive procedure.
3. dive site name and description.
4. emergency procedures.
5. assigning buddies. - ✔✔All of the above.
A dive briefing should include the dive site name, a site description, your role and how
divers will be able to recognize you, entry and exit techniques, dive procedures,
emergency procedures, a signal review, roster and buddy check, environmental
orientation and a predive safety check reminder.
✔✔You can prepare to handle novel problems at a dive site by (choose all that apply):
1. increasing your knowledge, skills and experience.
2. paying attention to steps required to deal with familiar and unfamiliar situations.
3. gathering physical resources. - ✔✔1. increasing your knowledge, skills and
experience.
2. paying attention to steps required to deal with familiar and unfamiliar situations.
You prepare to handle problems by having field-specific knowledge, relevant skills,
experience and equipment, and by paying attention to the steps required to deal with
each familiar and unfamiliar situation.
✔✔True or False:
It is important to include an environmental orientation in dive briefings because it helps
divers dive so that they minimize effects to the environment and familiarizes those with
little or no experience with the specifics of the environment. - ✔✔True.
An environmental orientation informs divers about the unique aspects of the particular
dive environment along with how to avoid disturbing or damaging the environment. This
is especially important for divers who have little or no experience in the local area.
✔✔To help divers interact responsibly with the environment, you should suggest that
they should (choose all that apply):
1. dive carefully to protect the ecosystem.
2. secure gauges and alternate air sources so they don't drag.
3. only touch or pick up creatures that seem docile.
