Abstract
In Korea, the inspection and maintenance intervals for pressure relief devices (PRDs) are determined by the installation's purpose and the substances being handled. The law mandates inspection frequencies ranging from one to four years, depending on the associated economic and safety risks. This study aims to assess whether the current legal requirements for PRD inspection intervals can be made more flexible, drawing on empirical data from incident case analysis, site visits, and surveys. We examined PRD installation and operating conditions through site visits to 65 workplaces and surveys of 117 workplaces and stakeholders to identify challenges related to PRD inspection cycle regulations and their practical applicability. Based on these findings, we propose moving from a regulated to a self-regulated PRD inspection cycle, in collaboration with industry experts and government agencies. The results of this study are intended to support improvements in chemical process safety management policies in Korea.
