Summary
An engineer suffered fatal head injuries when trapped pressure propelled an explosion-proof enclosure cover during removal. Leaking sample gas or instrument air components had pressurised the enclosure, which lacked pressure indication and relief. Lessons address identifying susceptible enclosures and developing mitigation with manufacturers while preserving electrical certification.
