How long must OSHA records be kept for?

The correct answer is that OSHA records must be kept for a minimum of 30 years. This requirement is in place to ensure that there is a long-term record keeping of employee exposure to hazardous substances, including lead, which can have serious long-term health effects. This extended retention period is crucial for addressing potential health issues that may arise long after exposure has occurred, allowing for proper tracking and response to any related medical concerns.

Maintaining records for 30 years aligns with the understanding that certain health effects from exposures may not manifest until many years later. By preserving these records, employers can provide necessary documentation to workers or their families if an occupational illness is diagnosed that can be traced back to exposures recorded during their employment. This practice is part of OSHA’s broader commitment to workplace safety and health, ensuring that employees have the information they need regarding their exposure to hazardous substances throughout their careers.
