What must flame effect operators maintain according to NFPA 160?

Flame effect operators must maintain an adequate supply of fire extinguishing equipment as outlined by NFPA 160. This requirement is critical for ensuring safety during performances where flame effects are used, as there is always a risk of fire when working with combustible materials. Having the appropriate extinguishing equipment readily available allows operators to respond quickly and effectively in case of an emergency, minimizing potential harm to the audience, the venue, and participants.

Other considerations, such as maintaining a log of audience attendance, a daily schedule of flame effects, or a secure area for operator training, are important for operational planning and documentation. However, they do not directly address the immediate safety measures that must be taken during the execution of flame effects. Ensuring a sufficient amount of fire extinguishing equipment is a proactive safety approach that prioritizes the well-being of everyone involved.
