In 2010 the Safety Commission Unit (SC) became the Occupational Health & Safety and Environmental Protection Unit (HSE) comprising the groups: Radiation Protection (RP) and Safety Engineering & Environment (SEE).

HSE’s mission was to

• support the Organization in the implementation and enforcement of its Safety Policy;

• monitor the implementation and accomplishment of Safety objectives aimed at a continuous improvement of safe working and operating conditions as well as environmental protection;

• grant safety clearance on behalf of the Director-General for special equipment, installations, experiments and projects with major safety implications.

In 2016 with the appointment of a new Director-General, the CERN management reorganised some sectors. The HSE unit structure remained unchanged.
