Medical Gas Regulations in the UAE: Authorities and Inspections

Who regulates what: DHA, DOH, MOHAP and Civil Defence

Medical devices are registered with the relevant authority, which at federal level is MOHAP. Facility licensing is emirate-specific: the Dubai Health Authority (DHA) licenses facilities and professionals in Dubai, and the Department of Health (DOH) does the same in Abu Dhabi. Other emirates follow MOHAP or their own local health authority. Each body publishes facility guidelines and may add its own checklist for engineering systems.

Civil Defence is a separate stream. Oxygen is an oxidiser, cylinders are pressurised, and storage rooms and plant rooms fall under the fire and life-safety code, so approval of cylinder manifold rooms, gas storage and plant ventilation normally runs through Civil Defence drawings review, independent of the health authority.

Technical standards behind the requirements: HTM, ISO 7396-1 and NFPA 99

The UAE has no national medical gas code written from scratch. Authority guidelines and project specifications usually point to recognised international documents. Two families dominate: the British HTM 02-01 for medical gas pipeline systems, and the American NFPA 99. For many projects the HTM reference is the working one, which is why searches such as HTM UAE or HTM Dubai are so common among consultants. ISO 7396-1 defines the pipeline systems for compressed medical gases and vacuum, and ISO 9170-1 covers terminal units.

The practical consequence is that the edition and the reference code are set per project, in the tender documents and the authority approval. Do not assume one code covers everything: HTM and NFPA 99 differ in how they classify systems, size sources and test installations, so a design should state clearly which one it follows, and avoid mixing rules from both without the consultant's written decision.

• HTM 02-01 / ISO 7396-1: pipeline design, sources, alarms, testing
• ISO 9170-1: terminal units and outlet interchangeability
• NFPA 99: alternative framework, often used by US-influenced consultants
• Civil Defence code: storage, plant rooms, fire separation

What DHA and DOH inspectors typically look for

Requirements for DHA medical gas and DOH medical gas systems are best confirmed directly with each authority, because guidelines are revised. In practice, inspectors and appointed consultants look at a familiar set of evidence: approved drawings, a named competent person for the installation, material and cleanliness records, commissioning and test reports, and a working alarm system.

Expect questions on source redundancy (duplex or triplex plant with automatic changeover), emergency reserve, zone isolation through area valve service units, and pressure monitoring. A medical gas alarm system with clear clinical and operational alarms is almost always on the checklist, and so is labelled, colour-coded pipework.

Testing and handover documentation

Before any ward is connected, the pipeline is pressure-tested, checked for cross-connection, purged and verified for gas identity and purity. These steps are described in HTM 02-01 testing and commissioning practice and should be witnessed and signed. Keep every certificate: authorities and insurers ask for them years later.

Handover should include as-built drawings, valve schedules, alarm settings, outlet lists by room, manufacturer manuals and a planned maintenance schedule. A compliant system on the day of commissioning stays compliant only if maintenance is documented, so agree service intervals before the contract ends.

Choosing equipment that supports compliance

Equipment choice should make the paperwork easier, not harder. Ask each manufacturer which standards the product is designed to, which outlet standards are available, and what technical files and test records come with it. MZ Liberec, a Czech maker of medical gas pipeline components, supplies terminal units, alarms, area valve units and gas sources for such projects.

Ask your supplier to state in writing which authority approvals relate to the device and which relate to the installation, since they are not the same.
