What should you never do with solvents and brake fluid?

The correct answer highlights the critical responsibility of properly managing hazardous materials like solvents and brake fluid. Pouring these substances down the drain is dangerous because they can contaminate the water supply and harm the environment. Both solvents and brake fluid contain chemicals that are harmful to aquatic life and may pose health risks to humans if they enter the water system.

Appropriate disposal of solvents and brake fluid involves following local regulations, typically requiring these materials to be taken to a designated disposal facility or recycling center. This ensures that they are handled safely and disposed of in a way that minimizes environmental impact.

In contrast, storing solvents and brake fluid safely is necessary to prevent spills and accidental exposure, while using them for cleaning is acceptable but must be done with caution and awareness of their hazardous properties. Disposing of them in a designated area is the proper alternative that aligns with environmental health practices.
