Summary
Investigation of a fatal resin-plant explosion and fire following solvent vaporisation and release through an altered reactor manway. The report examines pressure-containment design, inadequate alteration assurance, agitator-dependent safeguards, alarm deficiencies and evacuation preparedness. Recommendations address low-pressure vessel guidance, safer process design and flame-resistant clothing.
