29 CFR 1904 provides for recordkeeping and reporting by employers covered under the OSH Act as necessary or appropriate for:
Enforcement of the Act,
Developing information regarding the causes and prevention of occupational accidents and illnesses, and
Maintaining a program of collection, compilation, and analysis of occupational safety and health statistics.
The purpose of 29 CFR 1910.1020 is to provide employees and their designated representatives a right of access to relevant exposure and medical records; and to provide representatives of OSHA a right of access to these records in order to fulfill responsibilities under the OSH Act. Access by employees, their representatives, and OSHA is necessary to yield both direct and indirect improvements in the detection, treatment, and prevention of occupational disease.
