French term or phrase:arrêt anti-retour de flamme
This is from a safety data sheet for liquid acetylene (dissolved).
In the section on disposal:
Ne pas évacuer dans les endroits où il y a un risque de former un mélange explosif avec l'air. Le gaz rejeté doit être brûlé dans un brûleur approprié équipé d'un **arrêt anti-retour de flamme**.
Ne pas rejeter dans tout endroit où son accumulation pourrait être dangereuse.
Contacter le fournisseur si des instructions sont souhaitées.
I've come across flame arrester, but non-return flame arrester? Any ideas?
Explanation: function of a flame arrestor is, by definition, to prevent flashback so the 'anti-retour' aspect is already implicit in the English term.

Flame arresters are autonomous safety devices that protect workers, environment, and plant against deflagration and detonation caused by flashback from a combustion process while allowing vapor flow.
Regulator or the cylinder in an LPG gas cylinder.
Tanks or vessels containing flammable material
Furnaces using pre-mixed gases or hydrogen atmosphere.
Arrester/arrestor seem to get about same number of hits.
Explanation: For "anti-retour de flamme", "flame damper". 100% certain.
There are a few possibilities for "arrêt" including "shutdown" (or "closedown"), a mechanism that shut down the burner in case of a flame blowback (as in the emergency shutdown we hope all nuclear reactors are equipped with).
