New chemical solution for dust suppression

| By Chemical Engineering



Sentinel dust suppressant (photo) is a proprietary chemical that is designed to adhere the finest silica particles to larger particles to prevent the fines from becoming airborne. The chemical is sprayed onto sand grains and adheres to the small dust particles, effectively trapping them. Silica dust inhalation can be hazardous to the health of workers, and recent OSHA ruling has limited the permissible exposure limit (PEL) for respirable silica dust in order to have a safer work environment. This liquid dust-control agent is effective on sands of all mesh size, including 100-mesh sand. The mobility of the application system allows it to be applied at any site without impacting normal operations, and the robustness of the chemical helps it maintain its performance after multiple transfer points, says the manufacturer. — Hexion Inc., Columbus, Ohio
