Flame Effects Guidelines

The primal simplicity of an open fire is great and all, but newfangled technology enables all sorts of spinning, swirling, squealing, pink-and-green fire magic, and Burning Man artists make full use of it. The thing is, flame effects involve lots of moving parts and high-pressure flammable fuels, so follow these guidelines to make sure you’re doing it right.

Flame Effect Definition

Flame Effect is defined as “The combustion of solids, liquids, or gases to produce thermal, physical, visual, or audible phenomena before an audience.” This includes all flames that are automated, switched, pressurized or having any other action than simply being lit on fire; as well as projects using propane or other liquid or gaseous fuels.

Safety Guidelines for Flame Effects

The majority of flame effects at Burning Man are Liquefied Petroleum Gas (LP-Gas) effects; LP-Gas is often commonly referred to as propane. Most of the guidelines below deal with LP-Gas as a fuel. Regardless of fuel type or technological basis, all Flame Effects must be constructed in such a way as to meet or exceed applicable laws, codes and industry standards.

The National Fire Prevention Association (NFPA) publishes numerous codes and standards for the construction and use of LP-Gas systems, including:

  • NFPA 54 – National Fuel Gas Code
  • NFPA 58 – Liquefied Petroleum Gas Code
  • NFPA 160 – Standard for the Use of Flame Effects Before an Audience

NFPA documents are available for viewing and purchase on the NFPA website and should be reviewed by all Flame Effects artists.

Construction of Flame Effects

  • All LP-Gas cylinders shall be designed, fabricated, tested, and marked in accordance with the regulations of the US Department of Transportation (DOT) or the ASME Boiler and Pressure Vessel Code.
  • All LP-Gas cylinders must have an unexpired certification date stamp and be in good working order. Tanks in poor condition or out of date are a danger to fill and may cause injury to the fuel team, the artists, and/or participants.
  • Each LP-Gas flame effect must have a single 1/4-turn shut-off valve as the primary emergency fuel shut-off. When closed, this valve must inhibit all fuel flow to the flame effect, regardless of how many LP-Gas cylinders are connected to the flame effect. This valve must be exposed and visible at all times, and must be clearly marked as the emergency fuel shut-off.
  • All components of the fuel system (fittings, piping, valves, connectors, etc.) must be designed and rated for both the type and pressure of fuel being used. The use of improper fittings can lead to leaks and failures in the fuel system resulting in fires and or injury.
  • All LP-Gas metallic piping and fittings that will operate at a pressure greater than 125 psi shall be schedule 80 or heavier.
  • All LP-Gas Hoses that will be operated in excess of 5 psi shall be designed for a working pressure of at least 350 psi and shall be continuously marked by the manufacturer to indicate its maximum operating pressure and compatibility with LP-Gas.
  • Air or pneumatic line is not acceptable as fuel hose. LP-Gas degrades rubber hose not specifically designed for use with that fuel. This results in the hose cracking from the inside out, potentially leading to a catastrophic failure.
  • Hose clamps are prohibited on LP-Gas hose at any pressure. All fuel hose connections shall be factory made, or constructed with a crimped fitting specifically designed for that purpose. Hose clamps are well known for cutting and chafing fuel lines or coming loose, possibly leading to catastrophic failure.
  • All metallic tubing joints shall use flare fittings. The use of compression fittings or lead soldered fittings are prohibited.
  • Accumulators, surge tanks and other pressure vessels in the system shall be designed, manufactured, and tested in accordance with the ASME Boiler Pressure Vessel Code or the Department of Transportation (DOT) for the pressure of the gas in use.
  • Any welding alteration of pressure vessels, or alteration or fabrication of other system components that hold pressure, must be performed by an American Society of Mechanical Engineers (ASME) certified welder, and must be stamped and certified as such.
  • If the fuel supply pressure exceeds the maximum allowable operating pressure (MAOP) of an accumulator or other pressure vessel, a regulator shall be installed between the fuel supply and the pressure vessel to reduce the pressure below the pressure vessel’s MAOP. A pressure relief valve shall also be installed in the pressure vessel, with a start-to-leak setting at or below the MAOP and a rate of discharge that exceeds the maximum flow rate of the supply container.
  • Fuel tanks for stationary flame effects must be protected from vehicle traffic and be well illuminated at night.
  • flame effects should be constructed and sited in such a way that the flame head and/or hot components are at least six inches from the playa surface, to prevent baking or scarring of the Playa.
  • Any artwork, towers or other structures that incorporate flame effects should be secured from the wind and encircled with an appropriate safety perimeter to prevent injury to participants.

Operation of Flame Effects

Flame Effect Operators

Flame effects operators and assistants must be 21 years of age or older and be trained in the use of fire extinguishers.

Operators and assistants must wear fire resistant clothing while operating flame effects.

Personal Responsibility

No carelessness, negligence, or unsafe conditions with flame effects shall be tolerated. Do not drink, take drugs, or smoke when working with flame effects.

Safety Perimeter

An appropriate audience safety perimeter (and performer’s safety zone if applicable) shall be established well in advance of flame effects operation, and must be approved by FAST. Because of the variety of artwork that incorporates flame effects, a member of FAST will help you determine the correct perimeter distance.

In any case, a 20′ zone around the flame effects must be kept free of all combustible or flammable materials, and nothing should overhang this zone.


Only people familiar with the safety considerations and hazards involved are permitted to connect/disconnect LP-Gas tanks, or to do liquid fuel filling. Wearing personal safety gear (glasses, gloves, etc.) during liquid fuel filling is required.

Daily Safety Check

A daily safety check of all flame effect components and connections is mandatory before operation begins. Never start operation of a flame effect until the daily safety check is completed. If a safety hazard is identified either during the safety check or during operation, the Fire Safety Liaison must delay or halt operation until the hazard is corrected.

Operating Guidelines

Never light a flame effect until all performers, safety monitors and participants are in place and ready.

Never operate a flame effect in such a way that it poses a danger to people or property.

Attending to Flame Effects

flame effects must never be left unattended. The winds in the desert are highly variable, and may create havoc in a poorly monitored installation. Any flame effect found running unattended will be shut down. Egregious and/or repeat offenses will result in the confiscation and/or disabling of the effect.

No Smoking or Open Flame

ABSOLUTELY no smoking or open flame within 10 feet any storage area where flammable liquids or fuel gases are stored. All fuel and flammables must be stored in approved containers which must remain closed except when filling or dispensing, or when connected to a system for use.

Material Safety Data Sheets

MSDS for any hazardous chemicals used in the construction or operation of the flame effect must be kept at the installation, so they are available to guide clean-up activities in case of a material spill, and to provide to emergency medical personnel in case of accidental exposure.
