NFPA 160, Flame Effects Before an Audience, is modified to
include the following additional requirements:
a) Definitions for use in this Section:
"Armed" means confirmation of ignition source.
"Arming" means the key is in the on position, sending a signal
to the FSU to light pilot for flame verification.
"Enable" means the system has power, safety valve open,
accumulator charging/propane lines charging.
"ESSV" means Electronic Solenoid Safety Valve.
"FSU" means the Flame Safety Unit, a UL-Approved device to
confirm an ignition source.
"Fuel tank" means the tank containing propane.
"Torch" means a gas flame effect no higher than 8" continuously
burning, Group I effect.
b)
The following are additions to the requirements of Chapter 7 (Use of Flame
Effects):
1) There shall be a horizontal
clearance of at least 10' between the effect and any overhead
obstructions.
2) There shall be a
horizontal clearance of at least 10' from any spotlight operator.
3) All temporary suspended truss components,
whether supported from the ground or from a building's ceiling, shall have
either a steel aircraft cable 3/8" galvanized wire rope safety backup
protecting standard polyester spansets (polyester roundslings) or use GACflexa
wire rope soft sling to attach truss to the chain motor.
c) The following Sections of Chapter 9
(System Components, Flame Effects Control Systems, and Design) are deleted in
their entirety and replaced as follows:
9.1.1. All flame effect control systems shall be designed and
installed to prevent accidental firing and unintentional release of fuel. All
firing systems must have at least one key safety interlock and that key should
be with the Flame Operator when the unit is not in use.
9.3.2.2. The amount of fuels that are supplied to the flame
effects shall be limited to that amount necessary for operation.
9.3.3. All flame effect control systems shall be manually and
automatically enabled according to a prescribed sequence of operations outlined
in the plan, which prepares the flame effect for subsequent arming and
firing.
9.3.4. The arming of the effect shall be manually and
automatically monitored and confirmed until the effect is fired.
d) The following are additions to
the requirements of Chapter 9 (System Components, Flame Effects Control
Systems, and Design):
1) The maximum fuel tank
size allowed inside a building or facility is 20 lbs.
2) Hoses shall be located and protected to
minimize exposure to physical damage or exposure to abnormally high
temperatures, such as temperatures that might result from exposure to
convection or radiation from heating equipment. Hoses shall be free from cuts
or defects. Identified cuts or defects shall not be repaired. Defective or cut
hoses shall be replaced. Hose that is exposed to moisture shall be constructed
of noncorrosive materials or shall be protected against external
corrosion.
3) The hose, at no time,
shall extend through the audience or seating area.
4) The hose shall not extend from one room to
another or pass through any partitions, walls, ceilings, or floors.
5) If more than one such cylinder is located
in a room, the cylinders shall be separated by at least 20'.
6) All system components, including but not
limited to hoses and connectors, shall be listed for their intended use and
compatible with the products they contain.
7) Any accumulators or hose shall be purged
of all fuel prior to removal from its location.
8) Appendices A and B of this Part are added
to provide for the minimum layout of propane flame effect devices.
9) All flame effect displays allowed before
an audience are limited to Group V or Group VI control systems.
e) The following are additions to
the requirements of Chapter 11 (Fire Protection Provisions):
1) At least 4 pressurized water or pump
extinguishers shall be readily available for use (with the manufacturer's
instructions).
2) Prior to

licensed premises must be made to inform the patrons of the locations of exits
and fire escapes at the licensed premises.
