Explosion Proof Lights have to be compelled to be sensible, none additional thus than a category one Div one lightweight. In today’s market, its exhausting to seek out this sort of sunshine and not pay a kings ransom. Read this, we predict you may like what we’ve to supply.
The proper application of business category one Division a pair of diode lights is crucial to take care of a safely operative lighting system wherever petrochemicals or alternative ignitible concentrations gases area unit gift however in a very controlled, confined, or in a very properly vented setting. For environments wherever ignitible gases area unit additional systematically gift, then a category one div a pair of lighting are higher fitted to best safety.
Our perfected class 1 division 2 LED lighting products have been designed to meet all qualifications for these environments along with a UL listing.
We found that matching this class 1 div 2 qualification with LED technology allows for companies to maintain a safe lighting system while reducing energy costs by up to 75% and reducing overall costs of a typical explosion proof class 1 div 2 lighting system.
Class I Environments
Class 1 environments are dangerous, typically there is chemical or fuel vapors that are highly explosive. So a light needs to be built well and pass all the tests. This is where you will typically find a class 1 light:Class I Locations
Class I locations are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class I locations are further subdivided into two Divisions and three Zones.
Class I, Division 1: There are three different situations that could exist to classify an area as a Class I, Division 1 location:
Ignitable concentrations of flammable gases or vapors may exist under normal operating conditions.
Ignitable concentrations of such gases or vapors may exist frequently because of repair or maintenance operations or because of leakage.
Breakdown or faulty operation of equipment or processes might release ignitable concentrations of flammable gases or vapors, and might also cause simultaneous failure of electric equipment.
Class I areas are those in which inflammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class I Environments include:
Class I, Division 2: One of the following three situations must exist in order for an area to be considered a Class I, Division 2 location: Volatile flammable liquids or flammable gases are handled, processed or used, but the hazardous liquids, vapors or gases will normally be confined within closed containers or closed systems from which they can escape only in the event of accidental rupture or breakdown of such containers or systems, or as a result of abnormal operation of equipment. Ignitable concentrations of gases or vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operations of the ventilating equipment. 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.
|Hazardous Material||Class, Division System||Zone System|
|Gases or Vapors||Division 1||Zone 0 and Zone 1|
|Division 2||Zone 2|
The frequency of occurrence determines the level of hazard for a location. The longer the material is present, the greater the risk:
|Frequency of Occurrence||Class, Division System||Zone System|
|Continuous||Class 1, Division 1||Zone 0|
|Intermittent Periodically||Zone 1|
|Abnormal Conditions||Class 1, Division 2||Zone 2|
