1 Isolation of Hazardous Energy CoW Technical Standard Version Date Approver 1.0 March 31, 2024 JO EHS
2 Introduction Isolation of Hazardous Energy (IHE) requirements are designed to prevent injuries to personnel, damage to property or adverse environmental impact due to the unexpected energization of equipment or release of residual and/or stored energy during constructing, installing, setting up, adjusting, inspecting, modifying, and maintaining and/or servicing machines or equipment. Potentially hazardous energy includes electrical, mechanical, hydraulic, pneumatic, kinetic, potential, thermal, chemical and radiation. This standard defines the requirements for the opening of process equipment and/or performing isolation of machinery, process and other industrial equipment, electrical equipment and overhead powerlines, vessels, piping, and pressure relief systems from sources of hazardous energy. The requirements of this standard are also relevant to non- intrusive isolation of hazardous energy that involves breaking the containment and controlling long-term isolations. Scope These requirements are not intended for emergency situations where loss of containment has occurred and …
