What is a primary requirement for flame effect burners under the NFPA 160 Standard?

The primary requirement for flame effect burners under the NFPA 160 Standard is that each burner must have a primary safety control and effect valve. This requirement is fundamental to ensure the safe operation of flame effects, as it provides a way to control the flow of fuel and the ignition of the flame safely. The primary safety control is designed to prevent unsafe conditions and ensure that the flame effects can be managed effectively during performances. Effect valves specifically allow for the precise control of the flame effect's performance, enhancing both safety and effectiveness.

This requirement emphasizes the importance of safety in situations where flame effects are used, as improper management of fuel and ignition can lead to dangerous conditions. Incorporating these controls is critical to minimize risks to both performers and the audience. The NFPA 160 Standard focuses heavily on establishing consistent practices to manage and mitigate risks associated with flame effects, making the safety control and effect valve essential components of flame effect systems.
