Competency of technical personnel and contractors who install, construct, maintain, repair
or operate piped gas systems are controlled under Act 501 through the registration of
competent person and contractor firm respectively.

Approvals are issued by ST to contractors before commencing installation work and after its
completion. Engineering drawings and calculations and certificates of completion and test
endorsed by the relevant competent persons have to be furnished for the approval
purposes.
Gas fittings, appliances or equipments installed in piped gas systems must also be of the
type approved by ST or other related government agencies.

In line with the provisions of the Gas Supply Regulations 1997, safety and technical
provisions prescribed by the following standards are recognised by ST as a basis for
reviewing and approving piped gas installations and equipment.
