How are Special Hazardous Wastes identified?

Special Hazardous Wastes are classified using specific identifiers to ensure safety and compliance with regulations. In the context of the correct choice, marking hazardous waste containers with yellow labels serves a critical purpose. The color yellow is universally recognized as a warning sign, alerting individuals to the potential dangers associated with the materials contained within. By placing these marked containers 25 feet apart, it helps maintain a safe distance to minimize risk in the event of leakage or exposure. This spacing can also facilitate easy movement and access while reducing the chances of accidents.

The other options do not adhere to commonly accepted protocols for marking and spacing hazardous waste. Marking containers with colors not typically associated with warnings or safety could lead to confusion or mishandling of hazardous materials. Additionally, failing to provide adequate spacing would increase risks by clustering containers, which could exacerbate incidents involving spills or exposure.
