In which context is a major spill defined?

A major spill is defined in the context of exceeding the defined trigger levels. Trigger levels are specific thresholds established to determine the severity of a spill based on the volume or concentration of the material spilled. When a spill surpasses these levels, it indicates a situation that may pose a significant risk to health and the environment, requiring immediate action and reporting.

This definition emphasizes the importance of predetermined criteria for assessing the impact of spills rather than arbitrary financial thresholds, visibility, or timing of the incident. By adhering to established trigger levels, organizations can respond appropriately to spills that have the potential to cause serious harm and ensure compliance with safety regulations.
