Codes, standards and regulatory framework (Hong Kong)
What this domain tests
The exam tests your command of the Hong Kong statutory framework and the supporting codes. You must know which instrument creates a duty, which code gives technical guidance, and which authority enforces it.
Statutory core
- The Gas Safety Ordinance (Cap. 51) is the principal legislation. It controls the supply, installation, use, storage and transport of gas and provides for registration of gas supply companies, gas installers and gas contractors.
- Subsidiary regulations include the Gas Safety (Gas Supply) Regulations and the Gas Safety (Installation and Use) Regulations, which deal with supply duties, installation work, testing, notification and incidents.
- The Electrical and Mechanical Services Department (EMSD), through its Gas Standards Office, enforces the Ordinance and issues Codes of Practice and Guidance Notes.
- The GU series of codes covers gas utilisation matters such as installation pipework, appliances and LPG installations. The codes are approved technical guidance; they support the law but are not themselves the Ordinance.
- Other relevant instruments include the Buildings Ordinance, the Dangerous Goods Ordinance (Cap. 295) for LPG storage, the Fire Safety (Buildings) Ordinance and occupational safety and health legislation.
Worked example
A new restaurant asks you to approve a gas installation. The work is commercial, not domestic. A registered gas contractor must carry out the installation, and the design must address pipework, ventilation, flueing, appliance siting and fire separation. The contractor submits plans and an installation proposal to EMSD for approval. After installation, pressure testing, purging and commissioning are witnessed and recorded. Gas is not supplied until the required inspection and approval are complete. If the aggregate LPG storage exceeds the exempt quantity, a Dangerous Goods licence is also required.
Traps that cost marks
- Treating a British Standard or a GU code as the statute itself.
- Assuming a domestic registration covers commercial work.
- Omitting EMSD approval or notification before gas supply.
- Forgetting the Dangerous Goods Ordinance when cylinders or bulk LPG are stored.
- Citing a code number or clause you cannot verify; state the principle instead.
