Which of the following is not a tool a first responder would typically utilize when dealing with a hazardous materials incident?

• A. Training Manual
• B. CHEMTREC Book
• C. DOT ERG Guidebook
• D. Placards

Answer: (A)

In a hazardous materials incident, first responders rely on quick-reference tools that provide immediate hazard information and guidance for action. The DOT Emergency Response Guidebook is a standard field resource that helps determine initial safety measures based on the product’s hazard class and shipping name, offering clear steps to take and avoid in the first moments of response. The CHEMTREC Book gives direct access to chemical experts and detailed product data when information isn’t readily known or when more technical details are needed. Placards and markings on containers provide at-a-glance hazard identification, guiding safe approach distances, PPE choices, and initial containment actions even before exact substance details are confirmed.

A Training Manual is valuable for pre-incident preparation and learning procedures, but it isn’t typically used as a live, on-scene reference during an incident. Therefore, it isn’t considered a typical field tool alongside the ERG, CHEMTREC, and placards.
