Safe handling procedures of chemicals are found in the __________.

The correct answer is based on the fact that Safety Data Sheets (SDS) are essential documents that provide detailed information about a particular chemical, including its hazards, handling procedures, and emergency measures. SDS are universally required for hazardous chemicals, which means they contain standardized information regarding safe handling, storage, and what to do in case of an emergency involving that chemical.

Each SDS typically includes sections detailing the properties of the chemical, first-aid measures, fire-fighting measures, and accident response procedures, making it a critical resource for ensuring safety in environments where hazardous materials are used.

While the other options, such as the Hazardous Materials Guide and Chemical Safety Manual, may contain relevant information regarding safety protocols, they do not provide the comprehensive and standardized information found in SDS, which are specifically designed for chemical safety and handling. The Workplace Safety Plan might address broader safety issues but would not necessarily focus specifically on chemical handling procedures as detailed in an SDS.
