The Occupational Safety and Health Standards are rules that outline how employers are to protect employees from hazards. There are four major groups of standards in Federal law.OSHA Standards protect workers from a wide range of hazards, and are grouped together into topical areas.Where there are no specific standards, employers must comply with the General Duty Clause of the OSH Act. OSHA also incorporates some other standards by reference to avoid having to duplicate research and work done by others.This means your protective eyewear must meet those standards; using non-approved eyewear would be considered an OSHA violation even though OSHA did not write the standard.
