The correct answer is: 30 years.
Here's why: Safety Data Sheets (SDS) or records of hazardous materials, where they were used, and when they were used must be retained for 30 years after the material's use is discontinued. This extended retention period is essential for ensuring that crucial information about hazardous materials is available for an extended period, even after their use has been stopped.
By retaining these records for 30 years, organizations can maintain a comprehensive history of hazardous materials, their usage, potential risks, and safety procedures associated with them. This extended retention period helps in tracking the impact of hazardous materials over a significant timeframe, enabling better risk management and decision-making processes.
In summary, the 30-year retention period for Safety Data Sheets or records of hazardous materials post their discontinuation is crucial for ensuring long-term safety, compliance, and risk assessment in handling hazardous substances.
