For proper emergency response regarding hazardous chemicals, which document is crucial to consult?

The most crucial document to consult for proper emergency response regarding hazardous chemicals is the Safety Data Sheet (SDS). The SDS contains essential information about the chemical's hazards, handling and storage guidelines, emergency procedures, first aid measures, and regulatory information. In an emergency situation, quick access to this information is vital for ensuring safety and making informed decisions about containment, cleanup, and medical response.

While the Emergency Response Plan outlines procedures for responding to emergencies, it may not contain the specific details on individual chemicals, which the SDS provides. The Exposure Assessment Report focuses on evaluating potential exposures but does not serve as an immediate guide during an emergency. The Respirator Fit Guide is important for ensuring that individuals are properly fitted for respiratory protection but does not provide information on the hazardous properties or specific emergency responses related to the chemicals involved. Thus, for immediate and specific guidance in an emergency involving hazardous materials, the SDS is indispensable.
