Class 1, Div 2: Three situations exist for an area to consider a location as Class 1, Div 2.

• Facilities handling, processing, or using volatile flammable liquids or flammable gases. However, the hazardous liquids or gases confine within closed containers or closed systems. Only in the event of accidental rupture, breakdown, or abnormal operation of containers or systems will the hazardous substance escape.
• Mechanical ventilation prevents ignitable concentrations of gases or vapors from becoming hazardous.
• Similar to Class 1, Div 1 location, ignitable concentrations of gases or vapors might occasionally circulate. Yet, by utilizing positive-pressure ventilation from a source of clean air and safeguards against ventilation failure, the circulation of hazardous substances can be prevented.
