What classification of pressure is associated with containers for compressed gases?

The classification of pressure associated with containers for compressed gases is high pressure, which is defined as being greater than one atmosphere. This classification is crucial for understanding how these gases are stored and handled safely.

Compressed gases are typically contained in cylinders or tanks that are designed to withstand high internal pressures, often several times that of atmospheric pressure. For example, medical gases such as oxygen, nitrous oxide, and others are stored in cylinders at pressures that can exceed 2000 psi or more, which significantly exceeds standard atmospheric pressure at sea level (approximately 14.7 psi or 1 atmosphere).

Understanding that these gases are under high pressure is essential for personnel who work with them. It informs the safety measures that must be taken when transporting, storing, and using these gases, as improper handling can lead to dangerous situations, such as gas leaks or cylinder ruptures.
