How close would something like a cargo container have to be to a plane's engine to be sucked in?

In light of the incident that occured, where a cargo/ luggage container was sucked into the engine of a Japanese airliner, I was wondering, how close would that container have to be for this to occur. And if you know, what is the standard distance that it *should* have been to avoid something like this?

If you look on the ground at gate areas, you'll see semicircular markings on the ground that are about a 10 ft radius. Those are intended to keep stuff from getting sucked into the engine, and would be acceptable at lower power settings.How close would something like a cargo container have to be to a plane's engine to be sucked in?

What causes stuff like that is basic stupidity. I see incidents like this way too frequently, even on something so simple as lowering flaps. There are warnings in the job guide... ';Ensure area is clear of all obstacles before lowering flaps';





Then, Airman Bag-o-donuts comes in or calls on the radio, ';We've got a damaged flap.'; This is stuff taught very early on, and it shouldn't be an issue. People will find other stuff to blame it on, like being in a hurry, task saturation, etc, but it is plain stupidity to me. Ignorance can only come into play when the person isn't aware of the issues.
It shouldn't have been anywhere near the aircraft during the start procedure.. They haven't said exactly what happened, but to me -when I turn the red beacon on, it means...get yourself, others, or anything out of the way!
