What is A Class 1 Div 2 Area?
Class 1 Div 2 Definition
In Simple Word
Class 1 Div 2 location, C1D2 for short, Class 1 Division 2 for full name, means ignitable concentrations of hazards, such as flammable vapors and gases, exists under abnormal operation conditions.
In Quantitative Measurement
Class 1 DIV 2 light switch location means ignitable concentrations of hazards, such as flammable vapors and gases, present from 1 hour to 10 hours every year.
Class 1 Division 2 Electrical Requirements
In Accordance with NEC Article 500
A Class 1, Division 2 location is a location:
In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors 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
In which ignitible concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation and which
might become hazardous through failure or abnormal operation of the ventilating equipment, or
That is adjacent to a Class 1, Division 1 location, and to which ignitible concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors above their
flash points 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.

FAQ for Class 1 Div 2
Q
Does Class 1 Div 2 require explosion proof?
A
Yes, Class 1 Div 2 require explosion proof. According to Class 1 Div 2 requirements, considering the existing frequency of ignitable gas of Class 1 Div 2 is not higher than Class 1 Div 1, led
lighting should at least be constructed properly as “explosion proof” to limit the energy or isolate the ignition sources physically to prevent future explosion from happening, let alone the
spreading of explosion.
Q
What is a Class 1 Division 2 hazardous area? What is a C1D2 room?
A
Class 1 Division 2 hazardous area produce flammable vapors or gases which are further divided into Class 1 Division 2 Groups A-D. Hazardous material come out in abnormal conditions, such as system
or container failures, leaks or ruptures and do not expected to always exist, only under unusual conditions. C1D2 room should install electrical device abide by electrical rating class 1 division
2.

Q
Is NEMA 4X good for Class 1 Div 2?
A
Yes, when you intend to use electrical enclosure or panel in hazardous location, it is crucial to keep any combustible substances such as gases, vapors from entering into the confined housing and
influencing the working of the electrical components inside. NEMA 4 and NEMA 4X protection rating lay the rational foundation for anti-explosion performance of nema 4x class 1 division 2 explosion
proof enclosure.
Q
What is a Class 1 Div 2 enclosure?
A
Class 1 Division 2 Enclosure is used in facilities that flammable gases, vapors, and liquid materials are unlikely to present. Different from Class 1 Div 1 enclosure, Class 1 Div 2 enclosure should
be factory sealed with at least Nema 4X rated standard as “nema explosion proof”, housed by glass reinforced plastic, stainless steel or aluminum alloy material control the potential to bring about
ignition source via restrain high heat, temperature of electrical parts.
Q
Does Class 1 Div 2 require seal offs?
A
Yes, no matter what kind of outlets from such as conduit system, cables, cable entries of light fixtures, boxes, receptacles, switches, when the environment meet the electrical rating class 1
division 2 or flammable gas or vapors spread through any space or gaps within the whole system, sealing off for any bonding surface is essential to reduce the risk for concentration of hazards
subject to class 1 div 2 seal off requirement.
