Question

what should be ensured before attempting to lift any material?

• ensure the stacking ratio is no greater than 3:1
• look for any protruding nails, wires, or sharp edges
• use a safety harness

Explanation:

When lifting materials, checking for protruding nails, wires, or sharp edges is crucial to prevent injury to the lifter. Stacking ratio (3:1) is more about stacking stability, not direct pre - lift check for material handling. A safety harness is used in situations like working at heights, not as a general pre - lift check for all material lifting.

Answer:

B. look for any protruding nails, wires, or sharp edges
