DM chapter 2 Supervising Diving Activities Flashcards
What are the DM’s broad planning and briefing based on?
Evaluation of conditions.
Knowledge of divers based on what they said, general observations, log books and certification levels.
Reason for providing diver with guidelines (broad plan).
Allows individual buddy teams to plan their own dives.
Components of broad plan (orient divers to site and its conditions).
Temperature
Current
Thermoclines
Bottom composition
Hazards
Emergencies
Individual divers are responsible for planning their own dives because -
Divers will bear the consequences of the plan.
They know their experience and comfort level, so determine their own limits.
Conditions can and do change, divers must be able to revise the plan.
DMs can’t control divers, they are responsible for their own actions.
Easiest way to plan a dive.
Think through the dive.
-prep
-equipment
-paperwork
-what if (reasonably likely)
Best tide to dive during.
Slack high tide
Planning dives in remote areas
More in-depth planning.
Consider total time and distances.
Diving accounting procedures
Primary reason is to make sure every diver comes aboard before leaving.
-record names
-roll call
In dive planning for a group of certified divers, the DM’s role is usually to
provide broad planning information that divers use to plan their individual dives.
Divers must retain responsibility for
-planning dives within their own limits
-following thier individual plans
-revising their plans if conditions change during the dive
Thinking through the dive is the process of thinking about a dive from before it starts until after it ends, as a way of planning what you will need to prepare for and do. T/F
True
Rain can affect dive conditions by causing current, teperature change and/or visiblity changes. T/F
False
When planning dives for remote areas, planning must consider
-more logistics
-emergencies (distance/time)
-self sufficiency (dealing with problems)
The primary purpose of diving accounting procedures is to assure that every diver has
come back from the dive.
What individual differences in divers does a divemaster have to be prepared to accomodate?
-Skill level
-Physical challenges
-Learning challenges
-Culture
-Responsible behavior
Observable characteristics of responsible diving behavior include:
(6 items)
Planing dives within limits of training and experience.
Properly equipped.
Maintaining equipment.
Checking air supply frequently.
Staying within no stop limits, making safety stops and following safe dive practices.
Diving in an environmentally sensitive manner.
Four techniques to encourage responsible behavior.
- Good role model
- Remind divers of responsible diving behaviors.
- Make responsible behaviors easier logistically.
- Reward responsible behaviors.
Stress relief results from three approaches -
- Remove the stressor
- Provide accurate info
- Explaining procedures
Divers have individual differences, and you adapt your supervision techinques to meet their needs. Generally divers with (blank) want more guidance than do divers with (blank)
little experience; ample experience
Although it’s important to be environmentally sensitive, diving in an environmentally sensitive manner is not considered a characteristic of responsible diver behavior. T/F
False
Role model behavior is one way to encourage responsible diver behavior. T/F
True
You see a diver who lets theSPG and computer console dangle unsecured. Based on this you may suspect the diver may -
-be a novice
-be unaware of environmentally sensitive techniques
-have a poor attitude toward responsible diving practices
You notice a diver seems stressed about a dive and discover that it’s due to fears of not having enough air to make the planned dive, because the diver’s cylinder is only 2/3 full. How to assist the diver -
Give the diver a full cylinder.
Change the dive plan.
T/F If your role during the dive isn’t obvious, it is common to explain what your role will be during a dive briefing.
True
It is important to include an environmental orientation in dive briefings, because doing so -
- Helps divers dive in ways that minimize effects to the environment.
- Familiarizes those with little or no experience with the specifics of the environment.
What suggestions might be made to minimize impact on the environment?
- Do not allow equipment to dangle/drag.
- Do not handle, feed or ride on aquatic organisms.
- Leave human artifacts in place.
- Set a good example.
Two types of problems
- Routine
- Novel or unfamiliar
Problem solving skill steps
- Identify the problem precisely.
- Inventory your resources.
- Create several possible solutions.
- Choose the best.
- Assess and revise.
The 6 steps of Emergency Management
- Assess the situation.
- Act on your plan.
- Delegate.
- Provide BLS.
- Control the scene.
- Evacuate the patient.
