osh

OSH is an acronym with several meanings. The most widely used in professional and regulatory contexts is Occupational Safety and Health, the field focused on protecting people at work from injuries, illnesses, and hazards. This field encompasses risk assessment, safety training, workplace design, incident reporting, and compliance with national or regional regulations. In many countries, governments establish occupational safety standards and agencies to enforce them; in the United States, the federal agency is the Occupational Safety and Health Administration (OSHA), while OSH is often used as a broader descriptor for the discipline.

Open Source Hardware is another common meaning of OSH, particularly in technology and maker communities. Open Source Hardware refers to hardware designs that are released with open licenses, permitting use, study, modification, and redistribution. The movement emphasizes transparency and collaboration and has produced licenses such as the CERN Open Hardware License (CERN-OHL) and the TAPR Open Hardware License. Organizations such as the Open Source Hardware Association (OSHWA) coordinate standards and certification and maintain resources for developers and suppliers.

Other uses of the acronym are less common and context-dependent, including language- or organization-specific terms. When encountering OSH, the intended meaning usually depends on the field or region being discussed.
