It is our belief that our interpretation complies with the Occupational Safety and Health Act (OSHA) of 1970, Part 1910.184 Slings but may be subject to further clarifications, interpretations and future changes for which we cannot be held responsible. Such responsibility rests entirely with the employer/user of the equipment.
