I claim the ornamental design for profile for escape route marking, as shown and described.
FIG. 1 is a front end elevational view of a profile for escape route marking showing my new design, the rear elevational view being a mirror image and, therefore, not shown;
FIG. 2 is a front/top/right-side perspective view thereof, the rear/top/left-side perspective view being a mirror image and, therefore, not shown;
FIG. 3 is a front/bottom/right-side perspective view thereof, the rear/bottom/left-side perspective view being a mirror image and, therefore, not shown; and,
FIG. 4 is a front/top/right-side perspective view thereof on flooring and partly covered with a marking panel for use, the flooring and marking panel being disclaimed.
