Is it OK to leave scuba tanks in hot car?
Heat will cause the breathing gas inside the tank to expand, increasing the pressure. It’s recommended that the tanks are in a compartment with open air circulation. Tanks should not be stored in a car during hot weather or any time there is a possibility of excessive temperatures where the tanks are stored.
Can you refill a scuba tank with an air compressor?
A scuba tank generally must be filled at very high pressures, roughly 3,000 pounds per square inch (psi). Regular air compressors can only provide a small fraction of this pressure.
Should you dry your scuba cylinder in the sun?
It’s very important to keep your regulators dry on the inside and outside when storing them.

Why can’t you take a hot shower after scuba diving?
As the temperature increases, gases usually become less soluble in water solutions (such as blood). Thermal stress can contribute to bubble formation, which makes it one of the contributing factors in decompression sickness risk.
Should scuba tanks be filled with 100% oxygen?
For dives deeper than 66 m the gas mixture should contain less than 21% oxygen to avoid the risk of acute oxygen toxicity.
Can you breathe pure oxygen underwater?
Scuba diving beyond 20 feet with pure oxygen can be hazardous and can lead to lung damage and the condition known as oxygen toxicity, which actually decreases the amount of oxygen transported into the blood.
