EEMUA Publication 236 provides guidance on the development of a risk based approach for the management of overpressure for legacy systems. It provides a basis for understanding the risk associated with exceeding code allowable overpressures, and will help equipment operators make the decision as to whether procedural and/or physical plant modifications are required to maintain safe operations.

Applicable to legacy systems only, the guidance defines a standardised approach that can be used to aid prioritisation of effort towards code compliance. As a result, EEMUA 236 helps operators focus action where it will reduce or eliminate risk fastest and most effectively whilst also providing a framework for demonstrating the ALARP principle (As Low As Reasonably Practicable) where strict adherence to code may not be easily achievable without incurring disproportionate or excessive cost.
