Modular blast-resistant buildings play a crucial role in daily operations within the petrochemical industry for both temporary and permanent uses. These structures are used as control rooms, labs, admin buildings or temporary facilities for maintenance turnarounds. The petrochemical industry relies on blast-resistant buildings to meet safety and threat mitigation needs and protect personnel working in hazardous areas. While there are no official regulations for blast design, engineering best practices are outlined in API Recommended Practices 752 and 753 to guide both temporary and permanent structures, with the latter requiring more scrutiny. Permanent structures follow guidelines like conventional construction.
