Which item is explicitly mentioned as requiring containment in covered fire resistant containers until removal from the worksite?

• A. Solvent waste, oily rags, and flammable liquids
• B. Non-hazardous paper
• C. Water-based cleaners
• D. Dried paint chips

Answer: (A)

The main concept is that certain waste materials pose a significant fire hazard and must be kept in a dedicated, fire-rated containment until they’re removed from the worksite. Solvent waste, oily rags, and flammable liquids are the items that most require this protection because they release flammable vapors or can generate heat through oxidation. A covered fire-resistant container helps keep vapors contained and limits sources of ignition, dramatically reducing the risk of a fire starting or spreading while the waste is being managed or transported offsite. Non-hazardous paper and dried paint chips are generally less prone to rapid ignition when handled properly, and water-based cleaners typically have lower flammability than solvent-based products, so they do not demand the same level of containment. That’s why the first option is the one that explicitly calls for this protective measure.
