If you work with chemicals, you’ve likely come across Safety Data Sheets (SDS) in your daily operations. These documents are essential for ensuring safe handling, storage, and disposal of potentially hazardous materials. But a common question arises: Do SDSs expire? The short answer is no—Safety Data Sheets do not have a set expiry date. However, there are important considerations to keep in mind when it comes to their validity and accuracy.
No Fixed Expiration Date
Most regulatory frameworks, including OSHA’s Hazard Communication Standard (HCS) and REACH in the EU, do not mandate a fixed validity period for SDSs. Unlike food products or medications, SDSs are not assigned an expiration date upon creation. Instead, their relevance depends on the accuracy of the information provided.
Update When New Information Becomes Available
The primary rule for maintaining SDS validity is simple: update the document whenever new hazard information or risk management measures are identified. For example, if new scientific research reveals additional health risks associated with a chemical or if revised regulations require updated classifications, the SDS must be updated promptly to reflect these changes.
Regular Review Is Best Practice
While there is no legally required review period, it is considered good practice to periodically review SDSs—typically every three to five years. Regular reviews ensure that the information remains accurate, even if no significant changes have occurred. This proactive approach helps prevent outdated or incomplete information from being used in critical safety decisions.
The Importance of the Revision Date
To help users assess the timeliness of an SDS, most include a “revision date” indicating when the document was last updated. When working with SDSs, always check the revision date to confirm you’re using the most recent version. If the date is several years old, it’s a good idea to contact the supplier to verify whether the document reflects the latest information.
Why Do Some SDSs Have Expiry Dates?
You may encounter SDSs that include an expiration date. These are often added by manufacturers or suppliers as part of their internal policies or to align with industry-specific requirements. However, it’s important to understand that these dates are not mandated by most regulations and do not necessarily mean the SDS becomes invalid after that point. Instead, they serve as a prompt for users to review and update the document as needed. Always prioritize the accuracy and relevance of the information over any printed expiry date.
Practical Tips for Managing SDSs
- Establish a Review Schedule: Set up a routine to review your SDS library, even if updates aren’t mandatory. A two- to three-year cycle works well for many organizations.
- Monitor Regulatory Changes: Stay informed about updates to chemical regulations in your jurisdiction, as these may require SDS revisions.
- Communicate with Suppliers: Reach out to your chemical suppliers periodically to ensure you have the latest SDS for the materials you use.
- Train Your Team: Make sure employees know how to read and use SDSs and understand the importance of referencing the most current version.
In Conclusion
Safety Data Sheets don’t come with an expiration date, but that doesn’t mean they’re valid forever. Keeping SDSs up-to-date is critical for maintaining a safe workplace and ensuring compliance with regulations. By adopting a proactive approach to reviewing and updating your SDSs, you can stay ahead of potential risks and protect both your team and your business.
