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.

The guidance defines a standardised approach that can be used to aid prioritisation of effort towards code compliance and will help operators focus action where it will reduce or eliminate risk fastest and most effectively. It also provides a framework for demonstrating the ALARP (As Low As Reasonably Practicable) principle where strict adherence to code may not be easily achievable without incurring disproportionate or excessive cost.
