Which type of flame effect involves supervision by a main show control system?

The correct answer identifies Group V flame effects, which are characterized by their requirement for supervision by a main show control system. This supervision is essential because it ensures that the flame effects are safely integrated into the overall production environment and can be effectively monitored and controlled throughout their operation.

Main show control systems are responsible for coordinating various elements of a performance, including lighting, sound, and special effects. Having flame effects under the supervision of such a system enhances safety and minimizes risks associated with their use in front of an audience. Monitoring these effects allows for immediate intervention if any issues arise, ensuring performers and the audience remain safe.

In contrast, Groups I, II, and VI may not require this level of supervision, or they may involve different operational protocols that do not necessitate control by a main show system. Therefore, Groups I and II might involve simpler and lower-risk flame effects that can be managed without extensive dedicated oversight, while Group VI may encompass effects that have distinct operational requirements that are different from those of Group V.
