Coal World

Short answer: Coal dust blowing from loaded rail cars and stockpiles is a health, safety and maintenance problem. Railroads and mines use spray stations that coat coal with water or chemical binding agents, often called toppers, as trains roll through, forming a crust that reduces dust.

Dust control also lowers the risk of coal-dust fires and explosions in enclosed spaces. The footage, credited to BNSF Railway, shows coal trains passing through a spray station.

Video transcript: Coal World: Loaded Coal Trains Pass Under Spray Stations That Seal the Load

Did you know? Coal respray stations are designed to mitigate the dust generated during coal transport and processing. These stations spray water or chemical solutions over coal piles, conveyors, and loading areas to suppress airborne coal dust. The respray system often uses fine mist to ensure maximum surface coverage without overwetting the coal, which could affect its quality. This dust suppression is critical for reducing health risks to workers, improving air quality, and preventing potential hazards such as explosions, which can occur when coal dust accumulates in confined spaces. These stations are crucial for safety and environmental compliance in coal operations. NOW YOU KNOW!
