Forklift operation is a specialized job that requires operators to receive specific training. For instance, before operating a forklift, operators need to be familiar with its capabilities and limitations. This course specifies where to find information on safe forklift operation, and explains what this information means. It shows how features of forklift design impact forklift stability and capacity, and emphasizes that operators must be trained to safely operate forklifts according to their specific designs. The course highlights the concept of the stability triangle to help operators understand specific stability concerns presented by different load types, and shows how to safely accommodate these loads to avoid tipovers and falling loads. Finally, the course uses a field calculation to estimate safe load capacity for situations when a load exceeds the forklift's stated capacity. Forklift Operation 2: Stability and Capacity was developed with subject matter support provided by EnSafe Inc., a global professional services company focusing on engineering, environment, health and safety, and information technology. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments. Nothing herein, or in the course materials, shall be construed as professional advice as to any particular situation with respect to compliance with legal statutes or requirements.
