Captain of a widebody cargo aircraft reported a large bottle of flammable gas was improperly secured...

Narrative:

[Hazardous material] was loaded in an unsafe manner. A 50-100 pound bottle of flammable gas was 'held in place' by a loose fitting cargo net. Even after tightened; the bottle easily fell over with the slightest lateral force applied. Taxiing the aircraft and turning; takeoff and landing would have easily sent bottle of flammable gas crashing into surrounding hazardous material with potentially deadly consequences. Re-attempt demonstrated that hazardous material technician was trained poorly and had little understanding of the risks he was passing on to us. His attitude was pleasant; but the only reason the aircraft did not experience a significant hazard is because of the exemplary attention to detail by first officer. After unsuccessful loading attempts; bottle was removed and flight was accomplished uneventfully. Poor training and/or poor execution of hazardous materials procedures. Retrain; or replace individual involved. Teach technicians about the forces that impact cargo during flight.
