Group 3 flame effects are described as which of the following?

• A. An unattended outdoor flame effect with automatic flame supervision
• B. A permanently installed indoor flame effect
• C. A traveling entertainment flame effect outside
• D. An attended, temporarily installed flame effect for a specific production with limited operation, automatic controls, and visual flame verification

Answer: (D)

Group 3 flame effects are about temporary, production-specific setups that require an operator on site. They use automatic safety controls and include a method to visually verify that the flame is present during operation. That combination—attended, temporarily installed for a specific production, limited operation, automatic controls, and visible flame verification—best fits the description. The other options describe unattended, permanent, or traveling setups that don’t match the supervised, temporary nature of Group 3.
