What should you do with hazardous waste before disposal?

The correct course of action with hazardous waste before disposal involves triple rinsing the containers. This method helps ensure that any residual hazardous substances are adequately removed from the containers, thereby reducing the risk of contamination and exposure to harmful chemicals. Proper rinsing also prepares the containers for safe disposal according to local regulations.

Triple rinsing typically involves filling the container with water, sealing it, shaking it, and then pouring the rinsate into a designated hazardous waste container or disposal system. This is a critical step that aligns with best practices for environmental safety and compliance with regulatory guidelines.

In terms of the other choices, disposing of hazardous waste in regular garbage, mixing it with food waste, or leaving it outside can pose significant risks to human health and the environment. These methods can lead to leaching of toxins into soil and water, contamination of waste management systems, and endangerment of wildlife and people. Therefore, knowing and following proper disposal procedures, such as the triple rinsing method, is essential for responsible waste management.
