As an adjective it describes something designed to remain safe if failure occurs; the composition is semantically regular.

Etymology

Fail-safe joins fail ('to go wrong') and safe ('not dangerous') to show something made to stay safe even if a plan or part fails. So a fail-safe plan or method is one you can trust to keep working or keep you safe when problems happen.
