CCS is an emerging process and is not specifically addressed by GB health and safety legislation. However, existing legislation can be used to effectively regulate the safety of the CCS process chain. In particular the Health and Safety at Work etc. Act 1974 (HSWA) applies to CCS processes onshore and, from April 2013, offshore. Sections 2 and 3 of HSWA require employers to ensure the health and safety of workers and members of the public, so far as is reasonably practicable. CCS does not currently attract duties under GB major accident hazard legislation. However, the general duties under the existing legislation means that CCS operators will be required to take a proportionate approach to managing all CCS risks.
