In order to follow a perfect Industrial machine design process and improve any ergonomic environment, there are some major rules should be respected, especially if you are focusing on a preventive approach for an ergonomic assessment of your design. The department of labor of United Stated of America has just published the Occupational Safety and Health Administration categories. OSHA STANDARDS are rules that describe the methods employers are required to follow to improve the workers ergonomics and protect them from hazards.

One of the best regulations to follow are the OSHA, made to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance. There is a general list where you can find all of the Groups. Here you can find the Major Group 36 “Electronic And Other Electrical Equipment And Components, Except Computer Equipment”

This major group includes establishments engaged in manufacturing machinery, apparatus, and supplies for the generation, storage, transmission, transformation, and utilization of electrical energy. Included are the manufacturing of electricity distribution equipment; electrical industrial apparatus; household appliances; electrical lighting and wiring equipment; radio and television receiving equipment; communications equipment; electronic components and accessories; and other electrical equipment and supplies. The manufacture of household appliances is included in this group, but industrial machinery and equipment powered by built-in or detachable electric motors is classified in Major Group 35. Establishments primarily engaged in manufacturing instruments are classified in Major Group 38.
