Yes, however if you plan on using any open fire or flame effects in your art installation you must indicate this in your Art Installation Registration Questionnaire. Please read these guidelines for futher explanation: http://burningman.org/event/art-performance/playa-art/guidelines-registration/
Also please note that by having tiki torches, burn barrels or ANY fire on your project, there must be trained safety crew on hand at all times when the fire is burning. We do not allow any unattended fire or flame effects in Black Rock City.
