Before you lift the object, you should trace the entire path of travel to the final location to make sure the entire way is clear for the load. Tripping over obstacles or having to put down the load midway are hazards that can easily be avoided.
Just looking at an object can give you some idea of whether another team member or mechanical assistance will be needed to get the object from “point a” to “point b.”
