On The Floor
Look at the floor.
Is furniture in the way? Have it moved to create a clear path.
Are there rugs? Remove them or use double-sided tape or a non-slip backing.
Any newspapers, magazines or blankets on the floor? Remove anything that litters the ground.
Where are your lamps, telephones and extension cords? Place wires and cords next to the wall to avoid tripping over them. Or coil or tape them next to the wall. An electrician might need to install another electrical outlet.
