No, this is not an access restriction - people are allowed to go there 
whenever they like; it might just not be advisable.

I'd be against mapping non-quantifiable risks like this because it fails 
the https://wiki.openstreetmap.org/wiki/Verifiability test - as has 
already been discussed, one person might feel safe; another may not.  A 
"feeling of safety" likely has little bearing on actual risk (for 
example, during the breakup of Yugoslavia someone was worried about me 
visiting Prague) and there are many problems associated with assuming 
that one reflects the other (see e.g. 
https://www.washingtonpost.com/news/the-intersect/wp/2014/08/12/the-many-problems-with-sketchfactor-the-new-crime-crowdsourcing-app-that-some-are-calling-racist/ 
).

As to actual tagging of anything _quantifiable_, then perhaps the 
"tagging" list is the better place for that.
