What is the difference between FMEA and hazard analysis?

FMEA (Failure Mode and Effects Analysis) focuses on identifying potential failure modes in a system, while hazard analysis identifies potential hazards that could cause harm. Both are risk assessment tools but serve different purposes.

Can you give me an example of each?

Sure! In FMEA, an example could be analyzing a car's braking system to identify failure modes like brake fluid leaks. In hazard analysis, an example might be assessing a chemical plant for potential hazards like toxic gas leaks.

Which one is more comprehensive?

FMEA is often considered more comprehensive for understanding failure modes in detail, while hazard analysis provides a broader view of potential hazards. They complement each other in risk management.

When should I use FMEA instead of hazard analysis?

Use FMEA when you need to analyze specific components or processes for potential failures, and use hazard analysis when assessing overall safety risks in a system or environment.
