What is one of the suggested methods for trackout cleanup?

• A. Apply dust suppressants
• B. Install visual barriers
• C. Use a street sweeper
• D. Wait until the rain cleans the area

Answer: (C)

Using a street sweeper is considered one of the suggested methods for trackout cleanup because it effectively removes accumulated dust and debris from paved surfaces, especially from roads and driveways where construction activities may cause materials to spill over. Street sweepers are designed to pick up loose materials, including dirt, gravel, and construction particles, thereby minimizing the spread of dust into the surrounding environment. This method promotes cleaner roadways and helps in maintaining air quality by reducing airborne dust generation from trackout.

Other methods, while potentially beneficial, may not address the immediate need for cleanup as effectively as a street sweeper. For instance, applying dust suppressants can help bind dust particles and prevent them from becoming airborne but does not directly remove the debris already present on the streets. Installing visual barriers may contribute to reducing the movement of dust, but they do not provide a means of cleaning up existing trackout materials. Waiting for rain to wash away debris is not a reliable or proactive approach, as it can take time for rain to occur and may result in additional erosion or water pollution issues.
