§ 13.04.430. NFPA 160.

A new subsection, designated "8001.6 NFPA 160, Standard for the Use of Flame Effects Before an Audience," is added as follows:

8001.6 NFPA 160, Standard for the Use of Flame Effects Before an Audience. NFPA 160-2016 is available from the National Fire Protection Association, 1 Batterymarch Park, P.O. Box 9101, Quincy, Massachusetts, 02269-9101. The National Fire Protection Association Standard for the Use of Flame Effects Before an Audience is hereby adopted by reference with the following modifications:

Section 7.1.6 of NFPA 160 is added as follows:

7.1.6 The separation distance between the flame effect and the audience shall be such that the incident thermal radiation received does not exceed that calculated by the following equation:

T= [35 / q] ^ 1.33

Where:

T= time in seconds

q = incident thermal flux in kW/ m

The value of q can also be taken from Figure A7.1 of NFPA 160.

When applying the preceding equation to an effect with a duration of 4 seconds or less, the time used in calculating the maximum acceptable level if incident thermal flux shall correspond to the root mean squared (RMS) value of the peak incident thermal flux.

The incident radiation should not cause the surface temperature of the exposed skin of a member of the audience to exceed 111° F ( 44.0) °C. Incident radiation shall be measured with a radiometer. Skin temperature may also be measured with an infrared surface temperature thermometer or other equivalent means.

Section 8.1.3 of NFPA 160 is added as follows:

8.1.3 The operator shall be licensed in accordance with NRS 477 and NAC 477.
