The Swiss Cheese Model

The Swiss Cheese Model is a tool used to understand how accidents or failures occur. Imagine layers of Swiss cheese stacked on top of each other. Each layer represents a safety measure or defense. Each slice has holes, symbolizing weaknesses. When the holes in different layers align, a risk can slip through, leading to an accident. The model emphasizes the importance of creating multiple layers of protection to catch errors before they result in failure. By improving safety measures and addressing vulnerabilities, we can reduce the likelihood of harmful outcomes in various situations.
