What is required for flame effects used in a performance?

The requirement for flame effects used in a performance is that they must comply with NFPA guidelines and testing. This ensures that all flame effects are designed and executed safely, minimizing the risk of fire hazards to performers, crew, and the audience. NFPA, or the National Fire Protection Association, sets forth standards that govern the use of flame effects in theatrical productions, emphasizing the need for adherence to protocols that evaluate risk, establish safety measures, and conduct proper testing.

Compliance with these guidelines means that flame effects are not only aesthetically suited for the production but also safe for all involved. This training and adherence to standards help to prevent accidents and ensure that the effects work as intended while prioritizing safety.

The other options, while they may be important aspects of a performance, do not fulfill the essential safety requirements established by NFPA. Meeting aesthetic desires or obtaining approval from artists alone does not guarantee safe practices; similarly, utilizing only low-intensity flames without proper compliance with recognized standards can still pose safety risks. Thus, ensuring compliance with NFPA guidelines and testing is paramount for any flame effects used in performances.
