What type of hazards does the orange section of the NFPA label represent?

Answer: D — Specific hazards such as radiation or corrosion

The orange (or white, in some labels) section is for special hazards that aren’t captured by the usual health, flammability, or reactivity ratings. It flags specific hazards that require unique precautions, such as radiation, corrosive properties, oxidizers, or materials that react with water. These aren’t given a numeric 0–4 scale; they’re noted as special hazards that guide handling, storage, and PPE needs. So this section is about those particular hazards, not about how toxic, flammable, or reactive the material is in general. That’s why it points to specific hazards like radiation or corrosion.
