A "hazardous materials inventory" refers specifically to a comprehensive list that details the hazardous substances that a facility uses, stores, or disposes of. This inventory is crucial for safety and regulatory compliance, as it provides essential information for emergency responders, health professionals, and regulatory agencies regarding the types and quantities of hazardous materials present in a facility.

Having a well-maintained inventory helps ensure that emergency responders can take appropriate and informed actions during an incident involving hazardous materials, as it identifies the potential risks and necessary precautions. For example, if a chemical spill occurs, knowledge of the specific hazardous substances involved allows responders to implement the correct safety measures and utilize the proper personal protective equipment (PPE).

In contrast, other options focus on different aspects of safety and operations. A record of safe materials does not encompass the hazardous ones, a summary of emergency procedures relates to response plans rather than the materials themselves, and communication between responders and local authorities pertains to coordination during emergencies, which does not specifically identify the materials involved. Each of these elements plays a role in overall safety and preparedness, but they do not define what a hazardous materials inventory is.
