Breathing gas storage refers to the methods and systems used to store gases that are essential for respiration, particularly in environments where breathable air is not available. Commonly used in scuba diving, space exploration, and medical applications, these gases typically include oxygen and nitrogen. Storage systems can range from high-pressure cylinders to specialized tanks designed to maintain the gas's purity and pressure. The design of breathing gas storage systems is crucial for safety and efficiency. These systems must be able to withstand varying temperatures and pressures while preventing contamination. Proper maintenance and regular inspections are essential to ensure that the stored gases remain safe for use in critical situations.
