The rule does not require creation of any records, only preservation.
Access means the right to examine and copy records.
Employers are to inform their workers initially and at least annually of their rights to access to medical and exposure records. Records requests need not be in writing except where trade secrets are involved. Union and heath professionals must have specific written consent to gain access to employees' personal medical records but may examine exposure records without such consent. However, they must state the specific record needed and the occupational heath need for gaining access to the information. Heath professionals include physicians, occupational heath nurses, industrial hygienists, toxicologists, and epidemio ogists who provide medical or other occupational heath services to exposed employees.
