The Correct Answer and Explanation is:
Correct Answer:
Disposed of properly in designated waste containers.
Explanation:
After completing any scientific experiment, especially one involving chemicals, it is essential to handle chemical waste responsibly to ensure safety, environmental protection, and legal compliance. All chemical wastes should be disposed of properly in designated waste containers that are clearly labeled according to the type of chemical they are meant to hold.
Chemicals cannot simply be poured down the sink or thrown into regular trash bins. Doing so can lead to harmful reactions, environmental contamination, and even violations of safety regulations. Laboratories usually have specific containers for different types of waste. For example, there are separate containers for organic solvents, heavy metals, acids, bases, and biological materials. Mixing incompatible chemicals in one container can cause dangerous reactions, including fires, explosions, or toxic gas release.
Proper waste disposal also protects sanitation workers, wildlife, and the ecosystem. For instance, pouring mercury or strong acids down the drain can damage plumbing systems and pollute local water sources, harming aquatic life and entering the human water supply.
In addition to using the correct waste containers, laboratory personnel must follow all institutional or governmental protocols. These may include labeling containers with the type of waste and the date, wearing personal protective equipment (PPE) when handling waste, and ensuring that containers are sealed tightly and stored in a safe location until they are collected for disposal.
Moreover, waste disposal logs are often maintained to track the quantity and type of waste produced. This accountability ensures that all hazardous materials are managed responsibly and in compliance with safety and environmental laws.
In summary, all chemical wastes should always be disposed of properly in designated containers to maintain a safe working environment and to minimize harm to people and the planet.
