In designing a hydrogen system, it may be possible to reduce risk, even to the extent of "designing out" the hazard. Some steps to eliminate or reduce hazards are:

  1. Avoid using hazardous materials when possible
  2. Minimize quantity of hazardous materials
  3. Control the operating conditions (temperature, pressure, concentration, etc.) to reduce hazards
  4. Design facilities and equipment using:
    • inherent safety features and
    • fail safe designs
  5. Choose safer locations and consider:
    • outdoor installation
    • access control
    • safety barriers
    • remote operation (separation distance)
