Best Practices
  • Use the Proper Product. Do not fill large voids with foam products that generate a hazardous amount of heat.
  • Follow the Manufacturer’s Directions. 
  • Train Miners. Train miners before handling and using foam, grout, and resin products, including potential heat hazards.
  • Educate Miners on Chemical Exposure Hazards. Provide miners with Safety Data Sheets (SDS).
  • Foam Placement. Form used to support foam should be fire resistant or fire retardant.
