In NFPA 160, what does the term 'proximity' refer to?

The term 'proximity' in NFPA 160 specifically refers to the distance between flame effects and the audience. This concept is crucial because it directly impacts the safety considerations for both performers and spectators during a live event. Ensuring that flame effects are adequately distanced from the audience helps mitigate risks such as burns, smoke inhalation, and fire hazards.

In the context of safety standards, understanding this proximity allows for effective planning and allows for the implementation of appropriate safety measures to protect individuals watching a performance. This emphasis on audience safety is a fundamental principle of flame effects management outlined in NFPA 160. It highlights the importance of maintaining a safe environment while still allowing for the creative use of flame in performances.
