What do the terms catastrophic critical moderate and negligible described in the risk management matrix?

In a risk management matrix, the terms catastrophic, critical, moderate, and negligible categorize the severity of potential risks. "Catastrophic" refers to risks that could result in severe consequences, such as loss of life or significant financial impact. "Critical" indicates serious risks that could cause major disruptions or losses but are less severe than catastrophic risks. "Moderate" risks may lead to manageable impacts, while "negligible" risks are minimal and unlikely to have any significant effect on operations or safety.
