If you are in section 7.10, you are in the right place for basic "marking of means of egress", as long as you don't have ADA requirements, etc. Pretty much has to be adjacent to the exit, obviously leading you to the right place, high enough to be seen, etc.
Keep in mind that if your wall mount signs protrude from the wall, like end mounted signs in a narrow corridor, the bottom of the sign must be out of the egress path or above the minimum headroom height. Same rules apply to overhead signs. These rules are in section 7.1.5.
This is how we do it in CT anyway.
