The use of fireworks is prohibited.  If your team plans on using open flames of any sort, it is imperative that you have adequate firefighting equipment available. Never leave the fire unattended. If filming indoors and using smoke effects or hazers, check your fire alarm system. It may be hard to turn it off once triggered. Remember, fires can get out of control very easily. FILMING REQUIRES CONTROL.  You can also work around having an actual fire by doing an illusion of fire with a lighting effect.  If you have any questions or concerns, contact your local fire department.
