Risk control starts with risk identification and evaluation work at the design stage, right through to operation of the installation.
- Risk identification and evaluation is part of the research into hazards:
- a generic study on the risks associated with the 5,100 km
Transport Grid must be carried out every five years. The most recent was performed in 2014 and submitted to the government departments. It shows the risks across the whole Teréga grid, along with preventive and protective measures in place. Alongside it, there is a long-term programme to implement compensatory measures to increase the safety of systems in areas which have seen new urban development. Every year, land owners in the most exposed areas and the communities located in the vicinity of our structures receive a letter informing them about the structures present and the required conduct: declaration of works, easements, etc.
- as part of planning for construction or modification of pipelines or associated installations, a hazard study is conducted in order to identify and analyse risks. It sets out and justifies the steps taken to reduce the possibility and impact of accidents. In particular, it sets out the arrangements made at the system’s design (compensatory measures) and operating stages. This can be used to update the generic network hazard study.
- Actions to prevent and deal with accidents are organised through a safety management system (SGS) applied by the operator, Teréga. This SGS it's subject to internal monitoring and regular inspection by the Regional Directorate of the Environment, Development and Housing (DREAL).
- In order to ensure that its systems are operated under optimal safety conditions, Teréga has introduced activities to inspect and modernise its infrastructures through its monitoring and maintenance plan (PSM).
- Teréga stands prepared for any accident which may occur across its network, conducting regular exercises covering its monitoring and intervention plans (PSI), and involving the emergency services. Those emergency plans set out the organisation, intervention methods and resources to be implemented by the operator and the emergency services in the case of an accident on Teréga’s
Transport Grid, enabling their actions to be coordinated.
