Plastic (Type K) barriers must be filled with what material and be how tall?

• A. Soil 2ft tall
• B. Gravel 3ft tall
• C. Sand 3ft tall
• D. Concrete 4ft tall

Answer: (C)

Plastic (Type K) barriers are designed to provide an adequate level of protection around potentially hazardous materials, such as fuel tanks. The requirement for these barriers to be filled with sand is critical because sand provides excellent support and stability, effectively preventing any potential spillage from contaminating the surrounding environment. The height specification of 3 feet serves a dual purpose. It ensures that the barrier is sufficiently tall to contain any potential overflow or spillage from the tank, while also allowing for reasonable access for maintenance and inspections. This height effectively meets safety regulations, ensuring that it is visible and provides a sufficient barrier to hazardous materials. Using sand, rather than other materials like soil, gravel, or concrete, is important because sand can easily shift and conform to the shapes around it, optimizing the containment area’s efficacy. This aspect is crucial for adhering to regulations set forth for environmental safety and ensuring that there are no leaks or contamination occurring from the containment areas.
