How can I safely buy and use a Loadout Drop?

Since I’m not very good, I usually complete contracts at the edge of the map, buy a Loadout Drop, and try to use it there. However, for some reason, enemies are always nearby and ambush me. Even after I die and respawn, the same thing happens. Why are they at the edge of the map? If you have any tips for using a Loadout Drop safely, please let me know!
