Fire breathing is one of the most dangerous of all the fire arts, and not just due to the obvious risk of serious burns. To increase safety, fire breathers must avoid highly explosive fuels such as alcohol, spirit-based fuels, and most petrochemicals, instead using safer combustibles with a high flash point (>50 °C) and relatively low burn temperature.
Wind direction is extremely important when fire breathing. To determine the wind direction artists usually watch the flame on their torch. If the torch's flame is not being blown in any specific direction then it is safe to breathe. If a torch's flame is consistently blowing in a specific direction it is safe to breathe in that direction. Wind reversal can cause the flame to burn the breather.
