What does Chapter 4 of NFPA 160 cover?

Chapter 4 of NFPA 160 is focused on the general requirements for flame effects. This chapter sets the foundational guidelines that govern how flame effects are to be designed, implemented, and executed in a safe manner before an audience. It encompasses aspects such as safety measures, the environment in which the flame effects will be used, and overall responsibilities associated with conducting these effects. By establishing these general requirements, the chapter ensures that performers, technicians, and audiences are protected from the inherent risks of using flame effects in entertainment settings.

The other aspects like emergency procedures, technical specifications, or documentation requirements are covered in other chapters of the standard, focusing on specific operational details and protocols that support the overarching theme of safety established within Chapter 4.
