Summary
This safety bulletin examines the ConAgra factory explosion and similar incidents involving indoor fuel-gas purging. It explains direct displacement of air, hazardous gas accumulation and unreliable odour detection. Recommendations favour outdoor venting wherever practicable, with gas monitoring, ignition control, ventilation, removal of nonessential personnel and training addressing odour fade.
