Facility Design and Construction
A good facility design is necessary to achieve a safe hydrogen system installation. Hydrogen properties (as discussed in the previous section, hydrogen properties and leak detection play a major role in facility design. The following elements should be considered to ensure safe operations:
- Hydrogen Properties & Leak Detection A workspace can be configured to mitigate hazards by understanding and taking advantage of the characteristics of hydrogen.
- Loss Prevention It may be possible to reduce or eliminate risk by "designing out" the hazard.
- Ventilation Providing adequate ventilation will dilute hydrogen air mixtures, minimizing hazards caused by leaks.
- Electrical Providing the correct electrical equipment and instruments will eliminate some potential ignition sources.
- Leak Detection Special techniques are required to reliably detect hydrogen leaks.
- Flame Detection Special techniques are required to reliably detect hydrogen flames.
- Storage and Use Selecting the right kind of storage and the proper location can go a long way towards reducing risk.
- Venting Vent systems are necessary to move hydrogen purged from the system to a safe location.
- Instruments and Controls Safety of the facility can be improved by using interlock systems working in unison with hydrogen and fire detectors.
- Construction Good facility construction is necessary to achieve a safe hydrogen system installation.
