More DescriptionThis report was written in an effort to provide better control measures for low back pain (LBP) and low back disability in the mining industry. There are numerous factors associated with development of LBP, many of which can be effectively controlled while some cannot. Better job design is promoted as the best method of reducing cases of LBP and can also reduce the disability (i.e., lost time from work) associated with LBP when it happens. The report draws attention to what is currently known about LBP, what the causes are thought to be, and discusses recent back injury trends in the mining industry. Research describing unique physical demands in mining, such as the capabilities and limitations of working in awkward postures, is also presented. Methods that can be used to prevent initial LBP episodes are provided, including facilities design and layout for materials and supplies, use of mechanical-assist devices, improved design of lifting tasks, and better seat design. Methods of reducing the disability associated with LBP (including workplace design, proactive return-to-work efforts, communication, and management commitment) are also discussed. The report concludes that control of LBP and disability in mining requires a comprehensive approach to limit the repetitive loading that can occur on the low back due to manual materials-handling tasks and exposure to whole-body vibration (WBV). Specific recommendations include the following: * Successful LBP prevention efforts require a proactive program that has strong management commitment and incorporates employee involvement. * More efficient supply handling systems and use of mechanical-assist devices can greatly reduce exposure to hazardous lifting tasks. * Lifting tasks should be designed to minimize low back stress. Tools to evaluate and redesign lifting tasks are presented. * Improved seat design can reduce exposure to WBV and improve posture, leading to reduced LBP risk. * The disability associated with LBP can be reduced. Getting the worker back on the job as quickly as possible is in the interest of everyone involved.
