| NFPA Definitions |
|
Class I, Division 2.
A location (1) in which volatile flammable liquids or flammable gases are handled, processed or used, but in which the liquids, vapors or
gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or
breakdown of such containers or systems, or in case of abnormal operation of equipment; or (2) in which ignitable concentrations of gases or
vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation
of the ventilating equipment; or (3) that is adjacent to a Class I Division 1 location, and to which ignitable concentrations of gases or vapors
might occasionally be communicated unless such communication is prevented by adequate positive–pressure ventilation from a source of clean
air and effective safeguards against ventilation failure are provided. [See Section 500–4(b) of NFPA 70, National Electrical Code.]
Class II, Division 2.
A location in which (1) combustible dust will not normally be in suspension in the air in quantities sufficient to produce explosive or ignitable
mixtures and dust accumulations are normally insufficient to interfere with the normal operation of electrical equipment or other apparatus; or
(2) dust may be in suspension in the air as a result of infrequent malfunctioning of handling or processing equipment and dust accumulations
resulting therefrom may be ignitable by abnormal operation or failure of electrical equipment or other apparatus.
[See Section 500–5 (b) of NFPA 70, National Electrical Code.]
