Great! In only 41 words, and seemingly off-the-cuff, you've crafted a perfectly reasonable definition of an 'acceptably physically safe space'.
The term 'safe' should never have been brought over like this to apply to psychological comfort. With physical safety, there is a clear and obvious event around which related concepts can be built: the event of physical damage to the body. We can point to those events, and it is easier to trace back a chain of cause-and-effect and discuss reasonable domains of responsibility.
With 'emotionally safe' spaces, there is no line that prevents the notion from being abused, and substituted for "the absence of anything I don't like".
