Prosthetics is a science that study, design, and make prosthesis/artificial limbs for individual with physical disabilities. Orthotics is a science that study, design, and makes supported body's devices (orthosis) to correct human's deformities. Making prosthesis/orthosis in prosthetics and orthotics industry needs long process. The process started with assessment, casting, modification, and other steps that are need repetitive action involving several hazardous materials. These hazards include biological hazard, physical hazard, chemical hazard, ergonomical hazards, etc. This condition made prosthetist/orthotist who works in the industry facing several health and occupational problems. A risk management needs to apply to control and minimize hazard exposure to the professional, thus will increase safety in the working place. Hazard identification and risk assessments are the very first step in risk management to control the impact of working condition in the manufacturing of prosthesis and orthosis. It can find the general causes, risks, and determining control to increase occupational health and safety in the industry. Experts from prosthetics orthotics industry asked to give weight in the hazardous process. Pareto method used to determine the most risks in the process.
