When encountering an unknown chemical on the job site, reviewing all Material Safety Data Sheets (MSDS) is the appropriate response because these documents provide crucial information about the chemical's properties, hazards, handling, and emergency measures. The MSDS can inform workers about potential risks, necessary personal protective equipment (PPE), and the correct procedures for dealing with the substance safely. This knowledge empowers workers to make informed decisions about how to proceed without putting themselves or others in danger.

By consulting the MSDS, a worker can assess the situation with a better understanding of the specific chemical in question. This is essential for maintaining safety and compliance with safety regulations. Making assumptions about the safety of an unknown chemical, contacting a supervisor without first gathering information, or disposing of the chemical without proper knowledge could lead to serious safety incidents or legal issues. Therefore, reviewing the MSDS is a fundamental step in ensuring both personal safety and workplace safety when handling unknown substances.
