For how long must employers retain exposure records for hazardous materials?

Employers are required to retain exposure records for hazardous materials for 30 years from the time of employment. This requirement is based on the principle that health effects from exposure to hazardous materials may not manifest immediately and can take many years to develop. By maintaining records for three decades, employers ensure they have the necessary documentation to assist current and former employees in the event of health issues related to occupational exposure. Additionally, this retention period aligns with regulations set forth by agencies such as the Occupational Safety and Health Administration (OSHA), which emphasizes the importance of long-term tracking of exposure for the health and safety of workers.
