In the Emergency Response Guidebook, the green highlighted entries indicate that a material is?

• A. A corrosive material
• B. An oxidizer
• C. A flammable solid
• D. A toxic inhalation hazard (TIH)

Answer: (D)

Green highlighted entries in the Emergency Response Guidebook signal a toxic inhalation hazard. This means the material can cause serious health effects or death from inhaling vapors, gases, or aerosols, often with rapid onset. Because TIH requires heightened respiratory protection and specific action distances, the guide flags these entries so responders can quickly recognize the need for appropriate PPE and upwind, isolated response procedures. Other hazards—like corrosives, oxidizers, or flammable solids—are indicated through different cues, so the green highlight specifically points to inhalation toxicity rather than those other hazard types.
