Review injury and incident records, inspection reports, sick leave, worker complaints and workers compensation claims for musculoskeletal disorders, noting that not all hazardous tasks produce reports. Use information from regulators, industry associations, unions, technical specialists, similar workplaces and consultants, and from designers, manufacturers, importers and suppliers about precautions. Look for trends by task, job or location, which may show a layout or work method problem and help set priorities. Observe how people actually work and look for changes that created new manual tasks, tools or equipment that does not work properly, and improvisations such as stacking mats or flattened cartons to stand on. Consider the combined effect of hazards, for example static posture with repetitive movement. Appendix D offers a worksheet.
