Standing Barbell Tricep Extensions - Safe?

Safe or not safe?
(As a long term tricep builder & military press supplement)

Given that at some moments of the exercise there is a similarity with the “behind the neck pulldown” which is not good for the shoulder joints.

Thanks for your opinions.

Do them seated or on a high incline bench and you’ll be better off. An EZ bar is probably easier on the wrists as well.
