HTM 02-01
Health Technical Memorandum 02-01: Medical gas pipeline systems
In plain words
What it covers.
NHS guidance for designing, installing, testing and managing medical gas pipeline systems (MGPS): oxygen, medical air, surgical air, nitrous oxide, vacuum and anaesthetic gas scavenging. It sets the roles of the authorised and competent persons, the permit-to-work system, alarm systems, area valve units and the testing needed before a system is used.
Who uses it: Estates teams, authorised and competent persons, medical gas contractors, pharmacists and clinical engineers.
A summary written by BMEssentia for learning, not the text of the standard. Always work from the current official edition and the manufacturer's instructions.
It covers
- Design of oxygen, air, nitrous oxide and vacuum systems
- VIE and cylinder manifold supplies
- Area valve service units (AVSUs)
- Alarm systems
- AGSS
- Testing and commissioning
- Operational management and permits to work
Key points
What engineers need to know.
- Only authorised persons (AP MGPS) may issue permits for work on medical gas pipelines.
- Every new or modified pipeline must be tested for cross-connection, purity and pressure before use.
- Area valves let one zone be isolated in an emergency without shutting the whole hospital.
- Alarm panels warn of supply and pressure faults in clinical areas and at the plant.
- Pipeline work affects every device downstream: ventilators and anaesthesia machines need a plan.
- Terminal units are gas-specific so the wrong device cannot be connected.
- Part A covers design and installation; Part B covers operational management.
