Employers have a broad duty to provide a safety and healthy workplace even where there is no specific regulatory requirement. Federal OSHA regulations cover broad aspects of occupational health and safety and offer a reasonable benchmark. However as an employer, you can always go one better. Some locations such as California have even more comprehensive regulatory requirements. Federal OSHA is your minimum standard. Do not neglect their requirements for general industry, the construction industry and shipyards. If you are not sure which regulations apply to your activities, ask OSHA to make a consultative visit to your workplace. If you would rather find and fix compliance gaps before OSHA identifies them, rely on your in-house safety team or perhaps hire an expert to assist you.
