Even if there are no guidelines specific to an industry, the employer still has an obligation under the General Duty Clause, Section 5(a)(1) to keep the workplace free from recognized serious hazards, including ergonomic hazards. OSHA will cite for ergonomic hazards under the General Duty Clause or issue ergonomic hazard letters where appropriate as part of its overall enforcement program. OSHA encourages employers where necessary to implement effective programs or other measures to reduce ergonomic hazards and associated MSDs. A great deal of information is currently available from OSHA, NIOSH, and various industry and labor organizations on how to establish an effective ergonomics program, and OSHA urges employers to avail themselves of these resources.
