Scuba Diving Tips & Safety

Can you scuba dive with a hangover? (Affects on decompression sickness)

Is it safe to scuba dive with a hangover and are you putting yourself at a higher risk of decompression sickness if you dive with alcohol in your blood? The risk of decompression sickness is said to be higher if you have been drinking. This is probably mostly as a result of being dehydrated before you dive. Your level of hydration is just one of the risk factors associated with decompression sickness.

At what depth can you get decompression sickness?

How deep can you dive before you have to decompress or at what depth you can get decompression sickness may depend on a number of factors. These factors include the divers’ bodily make up (i.e. whether or not they are obese). These factors also include diver fitness, including any medical conditions, such as a hole in the heart, hydration, hard exercise on the dive or afterwards and how cold the water is.

What are the signs and symptoms of decompression sickness?

The most common manifestation of decompression sickness is joint and muscle pain, as well as a skin rash or itching. But beware, as this may just be the beginning of worse things to come and should never be ignored. Medical advice should be sought if you think you may have decompression sickness or if you are starting to exhibit any of the symptoms listed below for decompression sickness or the bends.

What should you and your buddy do if separated during a dive?

If you get separated from your dive buddy during a dive, stop and do a slow visual 360-degree spin. In doing so always remember to look up and down too. Look for telltale signs like your buddy’s bubbles or any disturbance of silt or sand on the bottom. If you have an audio buddy signaling device like a tank banger or a similar, and if you can’t spot your buddy, use it to see if your buddy can locate you from the sound.

Why are scuba tanks filled in water? (7 key questions answered on air fills)

The reason why scuba tanks are filled in cold water is that a warm dive tank holds less air at a given pressure than a cool scuba tank does at the same pressure. This means that as the air inside the tank cools, the pressure of the air will decrease. Therefore by controlling the temperature of the dive tank during the filling process will increase the amount of air available when the tank is used on the next dive.
