What is the main characteristic of a Group V flame effect?

A Group V flame effect is characterized as temporarily installed with continuous operation under supervision. This means that while these effects can operate for extended periods, they must be monitored by a qualified individual to ensure safety and proper operation. Supervision is essential because it allows for immediate response to any issues that may arise during the use of the flame effects, thus minimizing risks to both performers and the audience.

Choices that imply unattended operation or a lack of supervision do not align with the safety requirements outlined in the NFPA 160 Standard. Continuous operation without supervision could lead to unforeseen hazards, whereas a Group V flame effect specifically requires oversight to maintain safety. Additionally, while the option regarding individual effects suggests a lack of supervision, it overlooks the critical aspect of monitoring that is necessary for safe operation during performances. The aspect of continuous use for more than 180 days does not specifically apply to the Group V classification, as the emphasis is on temporary installations that require supervision during operation.
