Hydrogen safety documentation should be made available to all personnel and should cover topics specific to your facility and any hydrogen equipment and processes there:

  • Roles and responsibilities
  • Availability of hydrogen safety training courses
  • Safety planning process
  • Current hydrogen safety plans
  • Results of the most recent hydrogen safety inspections in your facility
  • Operating and maintenance procedures for hydrogen systems
  • Reports on any hydrogen incidents or near-misses in your facility
  • Information pertaining to the technology of any hydrogen processes, including:
    • A block flow diagram or simplified process flow diagram;
    • Process chemistry;
    • Maximum intended inventory;
    • Safe upper and lower limits for such items as temperatures, pressures, flows or compositions; and,
    • An evaluation of the consequences of deviations, including those affecting the safety and health of employees.
  • Information pertaining to the equipment in the process including:
    • Dimensions and layout;
    • Piping and instrument diagrams (P&IDs);
    • Materials of construction
    • Electrical classification;
    • Relief system design and design basis;
    • Ventilation system design;
    • Design codes and standards employed;
    • Material and energy balances; and
    • Safety systems (e.g., interlocks, detection and suppression systems).
  • General hydrogen safety information (a library of applicable codes and standards, regulations, industry brochures, etc.)

Work documentation (e.g., work orders, baseline drawings) should always reflect the current hydrogen system configuration.
