Australian carriers do the same... required to inform pax of:
1) They are sitting in emergency exit row
2) They may be required to operate the exit in an emergency
3) The signal to open the exit
4) How to operate the exit
5) Checking the esit is safe
6) Not to open the exit if unsafe
Also the crew check suitability of pax to be seated there. Personally, if the pax aren't listening and refuse to listen when I ask (again) for their attention then they get moved. End of story.
Exit row briefings are covered by CASA regulations, I'm sure most other airlines are covered by this also.
You'd be surprised how many 'frequent flyers' have 'heard it all before' but then look very surprised that they are seated at a plug-type exit not a Type III outward-opening exit!!!!!!!!!!
