What happens if you fart while scuba diving?
Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.
What is a BCD in scuba diving?
A buoyancy compensator, also called a buoyancy control device, BC, BCD, stabilizer, stabilisor, stab jacket, wing or ABLJ depending on design, is a piece of diving equipment with an inflatable bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy at the surface, when needed.

Why can’t divers come up fast?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.
Is scuba diving bad for your lungs?
Can I be seriously hurt while scuba diving? Yes. The most dangerous medical problems are barotrauma to the lungs and decompression sickness, also called “the bends.” Barotrauma occurs when you are rising to the surface of the water (ascent) and gas inside the lungs expands, hurting surrounding body tissues.

Why is it dangerous for a diver to take a hot shower?
Exposure to warm or hot water after scuba diving can cause peripheral vasodilation and sudden discharge of even massive quantities of nitrogen bubbles into the venous circulation, with increased risk of DCS. Exposure to warm water (hot bath, showers etc.)
Can you dive without a BCD?
Sport and technical divers should never consider diving without a BCD that has an air cell. A BCD is just like any other ‘tool for the job’ in that you should pick the right BCD for the dive you are planning.
How do you wear BCD?
While wearing the BCD (and maybe gloves if you usually dive with them): Tighten and loosen, clip and unclip every strap and release on the BCD. Play with the inflator and deflator mechanisms. Orally inflate the BCD completely and make sure it’s still comfortable, not restrictive.
How long does a scuba BCD last?
BCD: With routine maintenance and proper care, I find they last approx 8 years (4000 dives) before replacement becomes preferable to repair. Minimalist backplate/wing style BCDs tend to be far more rugged and long-lasting.
