Morphology
The meaning is directly and compositionally derived from 'safety' (protection, preventing harm) + 'lock' (a fastening device): a lock that provides safety. This noun–noun compound follows a common cross-linguistic pattern, so a B1 learner who knows both constituents can readily infer the MWE meaning.
Etymology
Safety lock is a small lock put on a gun to keep it safe by stopping the trigger so the gun cannot fire by accident. So, it means 'a device that prevents a weapon from firing unintentionally'.
