Hydrogen safety documentation should be made available to all personnel and should cover:
- roles and responsibilities
- the availability of hydrogen safety training courses
- hydrogen safety information (a library of applicable codes and standards, regulations, industry brochures, etc.)
- results of the most recent hydrogen safety inspections in your facility
- standard operating procedures for the hydrogen systems in your facility
- reports on any hydrogen incidents or near-misses in your facility.
- information pertaining to the technology of the process, 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:
- materials of construction;
- piping and instrument diagrams (P&ID's);
- 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 or suppression systems).
Work documentation (e.g., work orders, baseline drawings) should always reflect the current hydrogen system configuration.
