Occupational Safety and Health Administration's (OSHA) Recordkeeping Standard, 29CFR1904, requires that certain employers maintain annual records of workplace injuries and illnesses. Records of workplace injuries and illnesses are maintained on an OSHA 300 Log each calendar year and summarized on an annual summary log or OSHA 300A Summary. The 300A is required to be posted in the workplace every February through April to show records from the previous years' injuries and illnesses. Please contact your ADP Risk & Safety Consultant if you have questions about OSHA Recordkeeping Requirements.
