Section 12-1.7 - Prevention of ignition

(a) All processes or operations using or generating air contaminants which constitute a fire or explosion hazard shall be protected from sources of accidental ignition. Unless such processes or operations are isolated by tight partitions or enclosures they shall not be conducted within 20 feet of any materials, devices or operations which produce flames or sparks including, by way of illustration but not by way of limitation, engines, motors, welding and soldering torches. All processes and operations within 20 feet of any spark or flame producing work such as welding shall be discontinued and all ignitible air contaminants, flammable liquids and accumulated flammable residue shall be removed from the area of the flame or spark hazard before such work is begun.

(b) Concentrations of vapors which may be present in enclosed areas shall be deemed to be flammable when any such concentration exceeds 25 percent of the lower explosive level.
