California’s OSHA consultation services (Division of Occupational Safety and Health) has created a website dedicated to improving manual material handling. The main page of the site contains an “Action Kit,” which includes a variety of Cal/OSHA publications, a presentation, a poster, and several checklists.
The site explains the risk factors associated with manual material handling and gives some tips to improve the fit between the demands of the work and the capabilities of the workforce.
The section of the website I found to be most useful describes ideas to help you make improvements to manual material handling tasks. While most of these ideas are engineering controls that actually reduce the risk, some of them are administrative and work practice controls that are not as effective.
