Section 1 exam

A balloon fully inflated and sealed at 10 metres/33 feet, would probably _______ during acsent to the surface. - answer ✅✅burst A cylinder with higher working pressure always holds more air than a cylinder with lower working pressure - answer ✅✅False. A cylinder's capacity depends upon both its working pressure and its internal capacity A depth of 10 metres/33 feet causes a pressure change of - answer ✅✅1 bar/ata A squeeze is caused by - answer ✅✅a pressure imbalance between the surrounding pressure and an air space Accessory weights - answer ✅✅can help you adjust your trim

As a newly certified PADI Open Water Diver, I will be trained to dive with buddy as deep as - answer ✅✅18 metres/60 feet As I descend, increasing pressure affects my - answer ✅✅mask, ears, sinuses As you descend in water the pressure - answer ✅✅increases Before each use I should ________ my equipment - answer ✅✅inspect Buoyancy is a force that pushes an object in water upward - answer ✅✅True Certain medical conditions can be hazardous while diving, so it is important to answer all questions on the Medical Statement honestly and completely - answer ✅✅True During ascent I feel discomfort in my ears. I should - answer ✅✅stop, descend slightly and allow trapped air to work its way out. Equalization is the process of - answer ✅✅adding air to an air space Failure to complete assigned independent study can create significant delays, and my instructor may have to cancel and reschedule sessions until I complete the assignment. - answer ✅✅True

I want to adjust my mask so the strap rests - answer ✅✅above my ears, over the crown of my head I'm descending and discover I can't equalize. The first thing I would do is - answer ✅✅stop my descent and see if the problem corrects itself I'm renting a scuba cylinder at a dive resort. Among the cylinders for hire, some have green and yellow bands that read "Nitrox." As a PADI Open Water Diver with no other training or instructor supervision, am I qualified to use these cylinders? - answer ✅✅No (Until you are a PADI Open Water and a PADI Enriched Air Diver) Identify the four systems that make up a scuba kit. - answer ✅✅regulator, cylinder, weight system, BCD if you take 6 liters of air from the surface to 20 metres/66 feet, the volume will be - answer ✅✅2 litres In recreational diving, the buddy system means diving with another diver or divers in a team that provides assistance and safety benefits. - answer ✅✅True It is important to master buoyancy control because it affects almost everything I do in and underwater. - answer ✅✅True

My BCD should fit - answer ✅✅fit snugly but not restrict breathing when fully inflated My BCD should have adequate capacity to easily float my equipment and me at the surface - answer ✅✅True My body responds to anxiety with increased breathing but slow breathing helps to reduce anxiety - answer ✅✅True My buddy and I descend to 12 metres/40 feet. I would expect to use my air___________ at 6 metres/20 feet. - answer ✅✅faster than My buddy is rinsing a BCD and partially fills the bladder with water. Is this consistent with recommended BCD care? - answer ✅✅Yes My local dive pro will usually set up my regulator components - answer ✅✅True My mask encloses my nose so I can - answer ✅✅equalize the mask My primary considerations when choosing fins are fit and - answer ✅✅blade size My SPG is always part of my dive computer - answer ✅✅False. Your SPG may be independent instrument or it may be integrated into your dive computer.

Scuba cylinders require testing _________ and visual inspection ___________ - answer ✅✅every 2-5 years, annually Snorkels are standard equipment for scuba diving because they allow me to breathe with my face in the water or in rough conditions without wasting my scuba air especially when I have little scuba air remaining - answer ✅✅True Some scuba divers prefer a snorkel with a flexible lower portion so it drops out of the way when not in use. - answer ✅✅True The _____________ is a safety device that relieves accidental overpressure by releasing air before reaching the pressure at which the cylinder would fail - answer ✅✅burst disk The density of the air in the previous question would be ______ the density at the surface - answer ✅✅3x The LPI mechanism inflates the BCD with air from my scuba cylinder. - answer ✅✅True The most efficient way to breathe dense air underwater is to breathe

• answer ✅✅deeply and slowly The most important consideration when choosing a regulator is - answer ✅✅ease of breathing

The most important feature in my weight system is its - answer ✅✅quick release The most important rule in scuba diving is to - answer ✅✅Breathe continuously and never hold your breath The three most important considerations in choosing scuba equipment are suitability, fit, and _____ - answer ✅✅comfort The two basic fin styles are _______ fins. - answer ✅✅adjustable and full-foot There's no real benefit to choosing the components of my scuba kit as an integrated package - answer ✅✅False.

4. If faced with a problem, stop, then maintain or restore slow, deep breathing. Your regulator consists of - answer ✅✅alternate air source, SPG/computer, first stage, low pressure inflator hose, primary second stage
