Which reference would you consult for specific information on a chemical or product?

The correct choice is to consult the Material Safety Data Sheet (MSDS) for specific information on a chemical or product. The MSDS provides detailed information about the properties of a chemical substance, including its hazards, handling, storage, and emergency procedures. It is a crucial resource in ensuring safety in environments where chemicals are used, providing guidelines for proper use and potential risks associated with the product.

This document is legally required for many substances and includes information that can help professionals understand how to handle chemicals safely and comply with regulations. It covers aspects such as toxicology, exposure limits, and environmental effects, making it invaluable for anyone working with chemicals in park maintenance or similar fields.

In contrast, the other options do not serve the same purpose: UBC refers to the Universal Building Codes, which pertain more to construction standards; USMC is typically associated with the United States Marine Corps, which wouldn't provide chemical safety information; DOM generally stands for Document Object Model, related to programming, which is not relevant to chemical safety information. Thus, the MSDS is the most appropriate and reliable source for the information needed in this context.
