Practise Q & A which will help you prior to your knowledge reviews
Here are some practice questions and answers to help you along:
Explain why even mild hypothermia can be a problem for divers, and how to avoid it.
How do you check for proper weighting when diving in your dry suit?
Why is it important to not dive with an excessively tight neck seal?
How do you attain positive buoyancy at the surface, and maintain neutral buoyancy underwater, and prevent dry suit squeeze when dry suit diving?
Describe how to add air to your dry suit while underwater.
How do you vent air from your dry suit while underwater?
What should you do if you become too buoyant due to excess air in your suit?
How can you cope with too much air in your dry suit legs/feet?
What should you remember about breathing if caught in a runaway or rapid ascent?
List what you should do if your dry suit floods.
It interferes with clear thinking, saps away strength and endurance.
To avoid, always wear adequate thermal protection before, during and after a dive.
Wearing dry suit, undergarment and all regular equipment, you should float at eye-level while holding a normal breath with an empty BCD. When you exhale, you should sink.
Can cause carotid sinus reflex which results in changes in your heart rate and possible unconsciousness.
At the surface, add air to BCD, not dry suit. Underwater, add air to dry suit to adjust for neutral buoyancy. Add a little air on descent and maintain neutral buoyancy to prevent squeeze.
Short, light bursts of air.
In a feet-down position, vent air through the exhaust valve regularly and gently.
Disconnect inflator valve hose (if it started the problem).
Immediately dump air from exhaust valve or by pulling the neck or wrist seals open – flair body while dumping air to create drag.
Rapidly tuck into a ball while rolling on to your back – dump air immediately if needed.
Be sure not to hold your breath during the ascent
Terminate dive immediately. Use BCD to regain buoyancy – drop weights if necessary. Service dry suit if necessary.
