The high popularity of gas has also increased the likelihood of gas accidents. Various gas accidents occur frequently, and there is an urgent need to explore effective management models and strengthen comprehensive, full-process control.

▶ Design Phase:

It is mainly reflected in the designers' insufficient understanding of the environment and inadequate consideration in the design plan.

▶ Construction Phase:

The main hidden dangers are that the construction unit's safety and quality management is not standardized enough, the system is not sound, and the skill requirements for the operators are either not strict or not provided with training.

▶ Operation Phase:

A large number of safety and quality issues were left over from the construction phase; the operating unit's safety inspection work is inadequate and lacks depth; residents on the user side have weak safety awareness.

▶ Focus on risk prevention and control throughout the full lifecycle of 'construction-operation', and build an integrated platform of 'assessment, early warning, rectification, and digitalization'. Through a risk diagnosis system covering the entire chain of design, construction, and operation, achieve risk prediction, risk management, and improvement enhancement:

• During the construction phase, provide process quality and safety assessment, special evaluations, delivery assessment, and on-site project management to ensure high-quality and safe project delivery.

• Operation Stage: Operational inspections (covering stations, pipelines, and end-user gas usage sites), emergency drills, user safety awareness campaigns, ensuring the safe operation of gas facilities and improving the level of industry safety management

• Quality and Safety Assessment

• Operation Assessment

• Special Assessment

• Emergency Response Capability Assessment
