What type of information do material safety data sheets (MSDS) contain?

Material Safety Data Sheets (MSDS), now commonly referred to as Safety Data Sheets (SDS), are essential documents that provide comprehensive information about the properties of a particular substance. The primary purpose of these sheets is to inform users about the characteristics of a substance and its associated hazards. This includes data on toxicity, reactivity, health effects, exposure limits, and safe handling practices.

The correct answer emphasizes that MSDS contain detailed information regarding the actual and potential hazards posed by a substance. This information is crucial for ensuring safety in workplaces where hazardous materials are used, handled, or stored, as it helps to mitigate risks associated with exposure.

The other options, while related to safety practices and information, do not capture the primary focus of the MSDS. Instructions on product use, legal regulations, and purchasing information are certainly important in the broader context of hazardous materials management, but they do not specifically reflect the core details about hazards and characteristics provided in an MSDS. The emphasis on identifying and understanding hazards is what makes the MSDS a vital component in workplace safety and compliance.
