Apply the CSB safety guidance to PCA pulp and paper mills that produce NCG and operate NCG systems, which includes all foul condensate tanks. For these NCG systems:

  • Apply effective process safety management elements using good practice guidance, such as CCPS Guidelines for Risk Based Process Safety, and Guidelines for Implementing Process Safety Management;
  • Consider further expanding process safety management program boundaries beyond the minimum legal requirements to provide heightened coverage of process safety hazards;
  • Apply NFPA 69, Standard on Explosion Prevention Systems, to provide effective explosion prevention;
  • Where explosions cannot be prevented in accordance with NFPA 69, apply NFPA 68, Standard on Explosion Protection by Deflagration Venting, to provide explosion protection;
  • Ensure safety instrumented systems (safety interlocks) achieve desired risk reduction by applying the life-cycle approach provided in ISA-84, Functional Safety: Safety Instrumented Systems for the Process Industry Sector;
  • Apply TIP 0416-09, Collection and burning of concentrated noncondensible gases: regulations, design and operation, for effective NCG system design and operation;
  • Provide workers with periodic training to ensure they have an understanding of all process safety hazards applicable to areas of their responsibility and job tasks, including the safety conditions needed to permit hot work.
