Good point! Indeed, "unsafe" area is meaningless for some services. Maybe it's better to define some new service URNs for the usage of these "unsafe" areas instead of adding a new attribute.

However, could we use "hotspotArea" attribute instead of "unsafeArea"?  It means the service is frequently requested or provided in these areas. This is meaningful for most services. For example:
For police service, these areas are the regions with high crime report. 
For restaurant service, these areas are the regions with a lot of popular restaurants.
......
Is this more general?

Sure.

If we define a new service URN for unsafe area of crime, maybe police departments would want to run such a service.

It depends on the specific service. For police service, change every month might be appropriate (normally the police departments give a monthly crime report). For marine service, maybe it can keep constant for years (submerged rocks are fixed).
