An MSDS sheet does not include which of the following?

An MSDS (Material Safety Data Sheet), now commonly referred to as SDS (Safety Data Sheet), is designed to provide comprehensive information about a specific chemical substance. Its primary focus is on the health and safety information relevant to handling and using the chemical safely.

Emergency response measures are included on an MSDS because they provide critical instructions to manage incidents involving the chemical, such as spills or exposure. Hazard identification informs users about the potential risks associated with the chemical, including health hazards and environmental impacts. First-aid measures are detailed to guide individuals on how to respond effectively in case of exposure or injury resulting from the use of the substance.

In contrast, an MSDS does not include information on where to purchase the chemical. This type of commercial information is irrelevant to the safe handling and risk management of the substance. The focus of the MSDS is strictly on safety and regulatory information, making the absence of purchasing details consistent with its purpose.
