The OSHA Forklift Truck Inspection Requirement
The underpinning OSHA requirement comes for the 1910 standard:
“1910.178(q)(7)
Industrial trucks shall be examined before being placed in service, and shall not be placed in service if the examination shows any condition adversely affecting the safety of the vehicle. Such examination shall be made at least daily. Where industrial trucks are used on a round-the-clock basis, they shall be examined after each shift. Defects when found shall be immediately reported and corrected.”
