What type of flame effect requires continuous supervision by a technician?

Group V flame effects are characterized by their potential hazards and complexity, requiring continuous supervision by a technician during their operation. This type of effect may incorporate various elements and is designed to produce substantial flame effects that can influence the performance and safety of the event. The continuous supervision is crucial to ensure immediate response to any unexpected incidents or fluctuations, thus maintaining safety for both the audience and performers.

In contrast, other groups, such as Group I, tend to involve simpler flame effects that may not require as intensive supervision. Group IV and Group VI may include standardized effects or those that can be managed with pre-set conditions, reducing the need for continuous technician oversight. Therefore, the unique requirements and inherent risks associated with Group V flame effects underscore the necessity for constant supervision to ensure safe execution in live settings.
