What are the two primary factors of risk associated with pressure vessels?

The two primary factors of risk associated with pressure vessels are consequence and probability of failure. Understanding these factors is essential in managing the safety and integrity of pressure vessels.

Consequence refers to the potential impact that a failure of the pressure vessel may have, including possible injury to personnel, environmental damage, and economic loss. Evaluating consequence helps determine the severity of risks and the potential need for mitigation measures.

Probability of failure, on the other hand, estimates the likelihood that a failure will occur. This assessment can be influenced by various factors such as material degradation, operational conditions, and maintenance practices. By understanding how likely a failure is to occur, organizations can prioritize inspections, maintenance, and monitoring activities effectively.

Together, these two factors create a comprehensive risk profile for pressure vessels, allowing for better decision-making and resource allocation to enhance safety and reliability.
