PADI - Section 3

How can I avoid disorientation (confusion) on a dive in either low visibility or very clear water?

Descend (go down) and ascend (go up) along a sloping bottom or by using a reference line.

What is the first thing I should do with an injured diver at the surface?

Make the diver float and check to see if the diver is breathing.

Imagine I accidentally get entangled in something. What should I do first?

Stop, think and slowly untangle myself.

Although it shouldn't have happened, on a dive I fail to watch my SPG and run out of air. If my buddy is close by, my best option is to __________. Another option is to _____________, if I'm in shallow water and the surface is closer than my buddy.

ascend using my buddy's alternate air source / make a controlled emergency swimming ascent

After getting an unresponsive (unconscious or dazed) diver out of the water, I should keep checking for

breathing.

I should take a local area orientation dive whenever I

dive in a new place

I can prevent most surface emergencies (problems) by

making myself float (positively buoyant) and reducing my physical effort.

There is a mild current on my dive. Normally, I should begin my dive

swimming against or into the current.

Most diver injuries caused by aquatic animals happen because

the animal is protecting itself from the diver.

Water movement, weather and the suspended particles (floating silt) in the water affect

underwater visibility.
