This Industry Guidance Note (“IGN”) serves as a reference on the legal requirements and processes pertaining to Combined Operation (“CO”) activities, in accordance with the Workplace Safety and Health (Facilities) (Control of Major Accident Hazards) Regulations (“COMAH Regulations”). The primary objective of this IGN is to ensure that Duty Holder(s) (“DHs”) adopt a consistent approach when preparing and submitting their Combined Operation Safety Case (“COSC”) to the Safety, Health and Environment National Authority (“SHENA”), the designated Competent Authority under the applicable law and regulations. A COSC is a joint Safety Case that must be submitted by the DHs of two (2) or more operated facilities engaged in a CO. Further details and interpretation regarding the term “Combined Operation” can be found in Section 5.1 of this IGN.

The Safety, Health and Environment National Authority (SHENA) reminds all employers, self-employed persons and principals at every workplace of their legal obligations under the Workplace Safety and Health Act, Cap 277 (WSHA), and the Workplace Safety and Health (Risk Management) Regulations to ensure the workplace hazards are properly identified, risks are assessed, and appropriate mitigation measures are implemented.
