How long must MSDS sheets be kept after ceasing the use of a chemical?

Material Safety Data Sheets (MSDS), now commonly referred to as Safety Data Sheets (SDS), provide essential information about chemicals, including their properties, hazards, safe handling, and emergency measures. According to OSHA (Occupational Safety and Health Administration) regulations, when an employer ceases the use of a chemical, they are required to keep the associated SDS for a minimum period of 30 years. This duration is crucial as it ensures that information on the chemical remains accessible for record-keeping, potential health investigations, or any future claims related to exposure.

Maintaining this documentation for 30 years supports safety and health considerations for workers who may face risks associated with previous chemical exposure. It provides vital data for evaluating long-term health impacts, occupational hazard assessments, and compliance with various environmental regulations. This period becomes particularly significant in industries where chemicals may have delayed health effects, necessitating long-term tracking and information access.
