What should be done to minimize fire hazards during a flame effect performance?

To minimize fire hazards during a flame effect performance, it is crucial to remove all flammable materials from the area. Keeping the performance space free of flammable materials significantly reduces the potential for ignition and the spread of fire. This proactive measure creates a safer environment for both performers and the audience, as it eliminates potential fuel sources that could exacerbate a fire situation.

While limiting audience size can help manage safety, it does not directly address the presence of flammable materials, which are a more immediate hazard. Performing flame effects indoors is not inherently safer; in fact, enclosed spaces often require specialized ventilation and fire suppression systems to handle the risks associated with flame effects. Increasing the amount of fuel used would escalate the risk of fire, making the performance more dangerous. Therefore, the effective removal of flammable materials stands out as the most reliable strategy for fire hazard minimization in this context.
