breaker tie needed? - Electrical Inspections - InterNACHI®️ Forum

This seems like a fairly straight yes in my mind, but wondering if there is reason it is not done in this case - 2 single pole breakers??? The panel is in an apartment building. The pic(s) are of the main panel in the basement - each apartment has a separate distribution panel. The bottom 40 amp breakers were labeled for the subject apartment. Notice the 60 amp breakers have breaker ties, while both the 40 amp breakers in the pic don’t have ties. What’s the reason?
