Determining Potential Severity

Examples of yes/no questions used to determine potential severity level:

• Could the change take the process outside the safe operating envelope?
• Does the change significantly alter the heat and material balance?
• Does the change introduce new molecules?
• The potential severity or significance of the change is also classified as either high or low.
• Checklists are generally used to determine the level of severity – the above questions are examples of typical checklist questions.
