What is the primary reference material for chemical information in hazardous materials?

The Hawley's Condensed Chemical Dictionary is recognized as a primary reference material for obtaining chemical information related to hazardous materials. This resource provides comprehensive details about chemicals, including their properties, safety protocols, handling procedures, and potential hazards. It serves as a concise yet thorough guide that helps hazardous materials professionals understand the characteristics of various substances, making informed decisions regarding safety and response.

The Merck Index, while a valuable resource, is more specialized and focuses on pharmaceuticals and organic compounds rather than serving as a generalized reference for all hazardous materials. Reactivity Sheets are useful for specific scenario evaluations regarding chemical interactions, but they do not encompass the vast amount of chemical data necessary for broad hazardous materials information. OSHA Guidelines provide regulatory requirements and safety standards but do not serve as a primary source for detailed chemical information. Thus, Hawley's Condensed Chemical Dictionary stands out for its breadth and utility in hazardous materials contexts.
