If you find it difficult to breathe you're overexerted. B Stop all activity and rest, holding onto something for support if possible. 16) If I work too hard and find it difficult to breathe underwater, I shouldī stop all activity and rest, holding onto something for support if possible.Ĭ swim immediately to my buddy and signal for help.ĭ do a controlled emergency swimming ascent (CESA - swimming up to the surface saying the ah-h-h-h sound).

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. Your regulator consists of five components. Please choose the correct number for the choices below. Each regulator part has a number next to it. Store it standing in a safe place and keep it away from high heat. Also, have it pressure tested at required intervals, usually two to five years. You should keep some air in the cylinder to prevent moisture from entering and causing corrosion. If you have a snorkel and mask, practise this skill yourself before the course.11) Which of the following is part of proper care for my scuba cylinder?ĭ Have it pressure tested every month. According to my instructor, most nervous divers have difficulty clearing the mask (I certainly did!).
