Analyze the question

The question asks for the most appropriate method to dispose of household hazardous waste, specifically using paint as an example.

Evaluate the options

• Delivering the waste to specified collection sites: This is the standard, safe, and environmentally responsible method for disposing of hazardous materials like paint, as these sites are equipped to process or recycle them safely.
• Diluting the waste with hot water, and pouring it down the drain: Pouring hazardous chemicals down the drain can contaminate water systems and damage plumbing, even if diluted.
• Placing the waste in sealed containers, and storing in a locked cabinet: This is a storage method, not a disposal method. It does not solve the problem of getting rid of the waste.
• Sorting the waste into coloured bags, and placing it with your household garbage: Household hazardous waste should never be placed in regular trash, as it can leak into landfills and contaminate soil and groundwater.

Connect to safety concepts

Using the Chemical Hazard Symbols knowledge point, we recognize that household hazardous waste contains materials that are toxic, flammable, or corrosive. Safe handling and disposal are critical to prevent environmental contamination and human exposure. Therefore, taking these items to designated collection sites is the correct procedure.
