How long must an SDS be retained after the use of a material is discontinued?

The correct retention period for a Safety Data Sheet (SDS) after the use of a material has been discontinued is 30 years. This duration is specified to ensure that information regarding the hazardous materials is still accessible for review, especially for any long-term health effects, disposal, or emergency response procedures that may be necessary well after the material is no longer in use. The extended retention period reflects the potential for long-lasting impacts related to chemical exposure and is aligned with guidelines aimed at promoting safety in environments where chemicals are used or stored.

While some may consider shorter retention periods like 5, 10, or even 20 years, these do not account for the comprehensive need to safeguard against all possible risks emerging from chemical use. The 30-year guideline helps ensure that enough time has passed to address any latent safety issues or regulatory inquiries related to the chemical in question.
