Some regulations-COSHH and those for lead, asbestos, ionising radiations and compressed air-state that records should be retained for much longer (up to 50 years) as ill health effects might not emerge until a long time after exposure.ealth records should not contain personal medical information. These must be kept separately and in confidence by the occupational health professional (See below for advice on medical in confidence records) .
For I-9s the requirement for retention is three (3) years or one (1) year after the employeeâs termination, whichever is greater. For OSHA records the retention period may go from 5 years for the OSHA 300 log to 30 years for the records of exposure to cancer causing agents. So as you can see there is no one set time frame. The unfortunate result of there being no one certain answer is that HR departments have a tendency to keep everything forever.
