Show answer & explanation
Correct answer: B
Concept
A hazardous-waste characteristic is identified by the mechanism through which a waste can harm people or the environment.
The standard characteristic framework names four mechanisms: ignitability, corrosivity, reactivity, and toxicity. A treatment or activation description is not one of those characteristic names.
Application
Ignitable substances represent fire behavior; corrosive substances represent destructive chemical action; reactive substances represent dangerous instability; and toxic substances represent harmful constituent release.
The recognized characteristic categories in the list are ignitable, corrosive, reactive, and toxic substances. Activated substances does not name an additional category in this framework.
Contrast
Activated, ignitable, corrosive, and reactive substitutes an activation description for toxicity.
Ignitable, corrosive, reactive, and toxic lists all four named characteristic categories.
Activated, corrosive, reactive, and toxic substitutes an activation description for ignitability.
Activated, ignitable, reactive, and toxic substitutes an activation description for corrosivity.
Result
The hazardous-characteristic classes are ignitable, corrosive, reactive, and toxic substances.
