Manual materials is the most common category of compensable injuries in the United States work force, with four out of five of those injuries involving:

When manually moving materials, employees should always try to lift it alone if a load is so bulky it cannot be properly grasped or lifted, when they cannot see around or over it, or when a load cannot be safely handled.

Prior to starting all demolition operations, OSHA 1926.850 (a) requires that:
