What is considered a primary hazard of non-flammable compressed gases?

The primary hazard of non-flammable compressed gases is high-pressure storage and explosive decompression. In this context, the high pressure at which these gases are stored can lead to dangerous situations if the cylinders are damaged, improperly handled, or experience a failure. When a cylinder or valve fails, the rapid release of gas can create a projectile hazard, and if a mixture of gases is involved, there could be potential for violent reactions. Understanding this risk is crucial for maintaining safety protocols and ensuring proper handling and storage of compressed gas cylinders.

Other considerations like visibility in storage areas, cylinder weight, and labeling are important for safety management but do not inherently pose the same level of immediate hazard as the risks associated with high-pressure storage and potential explosive decompression.
