Reason's Model of Organizational Safety

Reason's Model of Organizational Safety, often called the "Swiss Cheese Model," suggests that accidents occur when multiple layers of defenses in an organization have weaknesses or holes. These holes are caused by various factors like human errors, technical failures, or organizational issues. When these holes align, it creates a direct pathway for a hazard to lead to an incident or injury. The model emphasizes that safety isn't just about human vigilance but involves multiple safeguards working together to prevent accidents. Continuous assessment and strengthening of these defenses help reduce the chances of accidents happening.
