Final answer:
In a salvage operation, pictures should be taken down from the walls and placed with the furniture to protect them from damage.
Step-by-step explanation:
During salvage operations, pictures on the walls should be removed and placed with the furniture. This is to prevent damage to the pictures, which could be caused by water, smoke, or incidental contact from the salvage crew or equipment. By removing the pictures and placing them with the furniture, it ensures they are accounted for and can be better protected from the elements of the disaster or incident causing the salvage situation.
