What defines a "major accident hazard"?

A "major accident hazard" is characterized as a situation that poses a significant risk of a catastrophic event. This definition highlights the potential for severe consequences that could arise from such hazards, which often include incidents like explosions, fires, and toxic releases. Recognizing major accident hazards is crucial in process safety management as these can lead to extensive destruction, loss of life, and environmental damage.

The focus on significant risk distinguishes these hazards from minor issues or regular safety hazards that can be effectively managed with standard practices. Additionally, understanding these hazards helps to prioritize safety measures, regulatory compliance, and risk assessments that are necessary to mitigate the potential for disasters in industrial settings. Assessing and addressing these major hazards is a core component of safety protocols in industries dealing with hazardous substances.
