3.
Avoid pushing the purge button in the second stage during cold water
diving operations.
4.
Avoid high rates of breathing, and excessive inflation of buoyancy de-
vices or dry suits. The deeper the dive the greater the risk.
5.
Do not practice unnecessary buddy breathing, etc.
6.
Do not use your regulator to fill lift bags, etc.
7.
Keep YOUR regulator in YOUR mouth. In an emergency, offer the spare
regulator. When taking the spare regulator, do not hit the purge button to
clear the water (if possible). Clear the regulator with as long a first exhala-
tion as is safely possible.
8.
If the physical gear set-up allows, use two 1st stages and utilize one for
breathing air and the other one for inflation air. This will split the cooling
effect between the two regulators.
