The process of operating Haldon and Byrne's design was fraught with danger, as the mounting pressure could easily make the heated oil tank explode, a flaw which was not recorded as a problem with the historical fire weapon. In the experiments conducted by Haldon in 2002 for the episode "Fireship" of the television series "Machines Times Forgot", even modern welding techniques failed to secure adequate insulation of the bronze tank under pressure. This led to the relocation of the pressure pump between the tank and the nozzle. The full-scale device built on this basis established the effectiveness of the mechanism's design, even with the simple materials and techniques available to the Byzantines. The experiment used crude oil mixed with wood resins, and achieved a flame temperature of over and an effective range of up to .
