Documentation

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.
