MH-65 Temporary Sanding Space

The United States Coast Guard is seeking information regarding temporary sanding space solutions to support MH-65 fleet restoration efforts. The ideal solution would provide a contained environment for surface preparation activities, including sanding, grinding, and coating removal within existing hangar facilities. The solution must ensure personnel safety, asset protection, and environmental compliance. The Coast Guard requires an 18-month solution to perform aircraft and parts surface preparation, including sanding, grinding, and coating removal within existing hangar facilities. Some key requirements for the temporary sanding space solution include: • Compliance with NFPA 33, NFPA 409, and NFPA 410 • Ability to maintain a consistent negative pressure environment • Exhaust system design, including ducting and fan construction • Filtration system capabilities, specifically addressing control of hexavalent chromium and cadmium-contaminated dust • Integration with source-capture vacuum systems • Electrical and ignition source control • Safety and operational features, including integrated fire suppression systems and intrinsically safe communication systems The Coast Guard is interested in learning about available products, capabilities, and industry best practices that can facilitate efficient, high-quality restoration of MH-65 helicopters while maintaining safety and regulatory standards.
