A Sand and repaint it every year.
B Dry it in the sun.
C Keep some air in it.
D Have it pressure tested every month. - CORRECT ANSWER✔✔C Keep some air in it.
You should keep some air in the cylinder to prevent moisture from entering and causing
corrosion. Also, have it pressure tested at required intervals, usually two to five years. Have it
visually inspected annually. Store it standing in a safe place and keep it away from high heat.
See Equipment I - Cylinder Care.

Your regulator consists of five components. The first stage is the "hub" of your regulator and
supplies air to the components - the second stage, alternate air source, low pressure inflator
hose and SPG/dive computer.
See Equipment I - Regulators.

Question: 4) ___________ travels faster in water than it does in air. This is why you cannot
easily tell where it comes from.
A Light
B Current

D Sound - CORRECT ANSWER✔✔D Sound
Sound travels about four times faster in water than in air. This makes it difficult to determine
where the sound is coming from because it seems to come from all around or directly overhead.
