Elimination of Dust Fire Hazard at Paper Mills

• Wet dust collection system eliminates duct fire hazard at Scott tissue mill | Pulp & Paper | Find Articles at BNET - Annotated

  Excellent article published in Pulp & Paper Oct 2000 by Mark Williamson. The importance of addressing combustible dust related fires is highlighted here. Do you have spark detection and flame suppression as part of your dry dust collector system?

  • DUST IS AN UNDESIRABLE BUT inevitable byproduct of tissue manufacture. It settles everywhere in the machine room. In high concentrations, airborne dust is an occupational health concern
    

    • Maybe it just might be a good idea to add national industries (NAICS) in the paper sector as a potential for combustible dust related fires and explosions. Currently the paper sector does not exists in the OSHA Dust NEP. What do you think? - post by comdust
      
      
  • Scott Paper Limited in Lennoxville, Quebec,
    • Kruger Products Limited, formerly Scott Paper Limited, is Canada's leading manufacturer and distributor of towel and tissue products for consumer, in-home, use and for commercial, away-from-home, use. - post by comdust
      
      
  • The No. 5 machine at the Lennoxville mill generates high levels of dust. There are also high levels of static electricity in the mill, so dust sticks to the walls and the equipment.
    • So there is a combustible dust hazard with paper dust. Hmm..maybe someone at OSHA should also read this for helpful reference, so as to add the sector to the Dust NEP. - post by comdust
      
      
  • Machine cleaning was scheduled two times per week and each cleaning needed 45 minutes to 1 hour of downtime.
    • Housekeeping appears to be very costly - post by comdust
      
      
  • To significantly reduce airborne dust, reduce dust buildup and the potential for fires, and to lessen dust carryover to the final product, the mill looked for alternative dust control systems.
    • Here it is , the potential for combustible dust related fires. Fires are the precursors for combustible dust explosions. Yet they are ignored and dust explosions get all the emphasis instead. Fire departments are repeatedly responding to combustible dust related fired on a regular weekly basis - post by comdust
      
      
  • To protect against the spread of fires in a dry system, special fire control equipment such as spark detection systems, sprinkler systems, and fire doors are commonly used.
    • Notice the importance of best engineering practices as outlined in the NFPA combustible dust standards such as spark detection and flame suppression systems,. Flamex and Grecon are excellent sources for these systems. - post by comdust
