Which item is NOT listed as a reference material for recognizing a hazmat incident?

• A. ICD-10 coding manual
• B. ERG
• C. MSDS
• D. CHEMTREC

Answer: (A)

Recognizing a hazmat incident relies on quick-reference resources that identify hazardous materials and guide initial actions. The Emergency Response Guidebook is the standard field resource used to match a material’s placard, label, or shipping information to its hazards and recommended response measures. Safety Data Sheets provide detailed hazard information, including health and fire risks, required PPE, and first aid measures, which helps responders understand what they’re dealing with. CHEMTREC offers access to expert chemical information and can provide real-time guidance on a wide range of substances.

In contrast, the ICD-10 coding manual is a medical coding system used for classifying diagnoses and procedures in healthcare records and billing. It has no role in identifying hazardous materials or directing initial hazmat response, so it isn’t used as a reference for recognizing hazmat incidents.
