Question

if youre stacking loads on top of each other, what must you make sure of before placing the load?
the top load is lighter than the bottom load
there are additional supporting stacks nearby
the stack is at least eight feet from any racks
the top of the stack does not block more than two light fixtures

Explanation:

When stacking loads safely, a core principle is to place heavier loads at the bottom and lighter ones on top to maintain stability and prevent the stack from tipping over. The other options do not represent a fundamental pre-requisite for safe load stacking.

Answer:

The top load is lighter than the bottom load
