Can you leave scuba tanks in car overnight?

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.

At what depth does oxygen become toxic?

Oxygen toxicity occurs in most people when the partial pressure of oxygen reaches 1.4 atmospheres or greater, equivalent to slightly over 187 feet (57 meters) depth when breathing air (shallower depths when breathing oxygen concentrations greater than 20%).

How do free divers hold breath so long?

In preparation of a freedive you will start to make your exhales longer than your inhales. This decreases the heart rate and helps calm the body and mind to reduce oxygen consumption. Less oxygen consumed also means to be able to hold the breath for a longer time.
