Hazardous locations are places where a possibility of fire or explosion exists because of flammable gases, vapors or fine dust.
Zone0: An area in which an explosive gas-air mixture is continuously present or present for long periods of time.
Zone1: An area in which an explosive gas-air mixture is likely to occur in normal operation.
