(Section: 2 / Paragraph: d. / Line: 1)
For the purposes of Mission Possible, a “controlled” flame is one in which the fuel source for the flame is limited so that the produced is kept as small as possible but still capable of carrying out the required action. The flame should be shielded from the rest of the device so that it only impacts upon the intended target so that it completes the specified task and does not provide a fire hazard to the rest of the device. Furthermore, the flame should burn out quickly, not produce any additional flames, and produce a limited amount of smoke. Participants are reminded that the Mission Possible event will be held indoors in room equipped with smoke detectors and it is the expectation that a Mission Possible device does NOT set them off.
Event supervisors are encouraged to conduct a safety pre-check of all devices to make sure that no identifiable safety hazards are present. Fuel sources such as flammable liquids or gases, chemicals such as magnesium ribbon, and compounds such as gunpowder are unsafe and should not be permitted in a device. If the event supervisor has any doubt they are encouraged to err on the side of caution.
