Which class is represented by the word 'Oughta' in the mnemonic?

• A. Oxidizers/ Natural Peroxides
• B. Gases
• C. Poisonous/Infectious Substances
• D. Miscellaneous

Answer: (A)

Mnemonics for hazmat classes use the initial letter of each word to cue a specific class. The word “Oughta” begins with O, which signals the Oxidizers/Natural Peroxides category. That initial cue is how the mnemonic helps you recall this particular class, since other classes are represented by words starting with their own letters. Oxidizers and natural peroxides are hazardous because they can intensify fires or decompose violently, so recognizing the O for Oxidizers/Natural Peroxides is the intended mapping for this word.
