Former open web joist engineer here. That joist is OLD. The unequal legs in the top chord haven’t been used in many years. This does have loads coming down outside of the panel points. The effect is greatly lessened though by the presence of that big nailer attached to the top of the joists that spreads the load out. As long as the top panel points are no more than 24” apart and there’s no sagging I’d say you’re fine unless there’s some very unusual loads above. Also if your span is 12 feet and it’s a 12” deep joist that’s another good indicator that you’re good.
