The United States Occupational Safety and Health Administration (OSHA) is an agency of the United States Department of Labor dedicated to assuring safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance. OSHA regulates the retention and management of all safety records and incident reports.
Under the OSHA Recordkeeping regulation (29 CFR 1904), covered employers are required to prepare and maintain records of serious occupational injuries and illnesses, using the OSHA 300 Log. This information is important for employers, workers and OSHA in evaluating the safety of a workplace, understanding industry hazards, and implementing worker protections to reduce and eliminate hazards.
DOL (OSHA), 29 CFR 1910.1020 - Requires data relating to employee exposure or safety records must be retained for 30 years.
