English term (edited): safety override

It is relatively unusual to see 'safety' used as a nound like this in EN (it is perhaps commoner to see things like 'saefty device' etc.), but very common indeed in FR, so I don't think you need have any worries on that particular score ;-)

I feel sure this is just talking about defeating safety devices so that, for example a machine can be made to work even with the safety guards open; in this sense, I feel that 'contournement' perhaps works better than your own suggestion of 'outrepasser' — though as a non-native speaker of FR, I stand to be corrected on that point.

I would suggest consulting the glossary for 'override', as we have had this in various forms before, and I feel pretty sure you will find instances similar to your own context.
