System Safety and PRA Resources

This is a list of free handbooks, guides, and textbooks covering all of the tools of system safety and probabilistic risk assessment (PRA). To the best of my knowledge, all of the resources on this page are free and legal.

We have resources covering FMEA, FTA, PRA, System Safety, Software Safety, STAMP/STPA, GSN, and Bayesian methods. The resources are drawn from multiple industries, including automotive, nuclear, space, and aviation.
