Composition, hazards, and first aid measures are all parts of which reference?

The correct answer is the Safety Data Sheet (SDS). This document is essential in the context of hazardous materials, as it provides comprehensive information on a substance's composition, potential hazards, and necessary first aid measures.

SDSs are designed to inform workers and emergency responders about the health and safety risks associated with each chemical. They include sections on chemical properties, physical and health hazards, safe handling and storage, exposure controls, and personal protective equipment (PPE). The first aid measures section is particularly crucial, as it provides specific instructions on what actions to take in case of exposure or an emergency related to the chemical.

In contrast, other reference materials serve different purposes. The Dangerous Cargo Manifest is a shipping document that outlines the hazardous materials being transported but does not go into detail about health effects or first aid. The Emergency Response Guidebook, while valuable for guiding responders in emergencies, is more focused on immediate response actions rather than comprehensive safety and first aid details. The United Nations/Transport Canada Identification System facilitates the identification of hazardous materials in transport but does not provide the extensive information on hazards and first aid that an SDS includes.
