After learning a material's 3-digit guide number, what is the next step in the ERG workflow?

• A. Go to the orange-bordered section
• B. Check the blue-bordered material index
• C. Open the yellow-bordered hazard list
• D. Call CHEMTREC

Answer: (A)

The next step is to turn to the orange-bordered section. Once you have a material’s 3-digit guide number, the orange pages are the place that maps that number to the actual guide for that substance. There you’ll find the specific, action-oriented information you need: the material’s hazards, potential health effects, ignition or reactivity concerns, and the recommended immediate actions. It also includes the initial isolation and protective actions you should take for responders and the public, along with any essential safety precautions. The blue-bordered material index is used when you’re searching by name to find the corresponding guide number, so you’d use it before you know the number. The yellow-bordered hazard list offers general hazard information, not the material-specific response steps. Calling CHEMTREC is an option if you need more detailed data, but it isn’t the immediate next step after learning the guide number.
