Which reference materials are used to recognize a hazmat incident?

• A. ERG, MSDS, CHEMTREC, and placards
• B. Placards, ERG, CHEMTREC, and MSDS
• C. CHEMTREC, placards, ERG, and MSDS
• D. MSDS, placards, ERG, and CHEMTREC

Answer: (A)

Recognizing a hazmat incident relies on four kinds of reference materials working together. Placards on vehicles or containers give an at-a-glance indication of the hazard class, helping responders identify the risk from a distance. The Emergency Response Guidebook provides quick, action-oriented guidance for initial scene management, including suggested protective actions and isolation distances based on the material's guide number. The Safety Data Sheet (MSDS) offers detailed information about the chemical’s properties, hazards, PPE needs, and basic spill or exposure controls. CHEMTREC supplies a 24/7 information line to obtain current hazard data, product specifics, and expert guidance when details are uncertain or additional clarification is needed. Using all four resources together gives a responder a complete picture: visually recognizing the hazard, confirming actions with a field guide, understanding the chemical’s specifics, and obtaining real-time expert advice.
