According to OSHA, how is a pressurized vessel defined?

A pressurized vessel is defined by the Occupational Safety and Health Administration (OSHA) as one that operates at pressures greater than 15 pounds per square inch (psi) gauge. This definition is significant because it sets a standard for the safe handling, inspection, and regulatory requirements applicable to such vessels. Pressurized vessels are subject to specific safety protocols to prevent accidents and ensure that operational pressures are within manageable limits, minimizing risks such as explosions or ruptures.

The threshold of 15 psi is critical because it signifies the point at which additional safety concerns start to arise, requiring more stringent safety measures as dictated by OSHA. This definition helps ensure that safety officers and workers are aware that vessels operating at or above this pressure are subject to regulatory oversight and must adhere to established safety protocols, training, and maintenance requirements. Understanding this definition is essential for anyone involved in industries that utilize pressurized systems, as it directly impacts safety regulations and practices.
