Hazardous Area Lighting Classifications

Class ii division 1.
Hazardous area lighting classifications. Raytec manufacture a full range of globally certified spartan ex led luminaires to provide a lighting solution for any hazardous area application. From area to task flood to emergency we have a light fixture perfectly suited for use in hazardous corrosive and ordinary environments. Founded in 2005 with all products uk designed and manufactured in house raytec have an unparalleled background as the world leader in led lighting for security and safety with over half a million. Sources of such hazards include gases vapors dust fibers and flyings which are combustible or flammable.
Zoning as described above may be applied replacing gas atmosphere with dust air mixtures. Group type of hazardous material. One of the following three situations must exist in order for an area to be considered a class ii division 1 location. Available from 3 000 to 7 000 lumens the cpmv led is engineered to provide maintenance free illumination long life and high performance in class i division 2 areas.
Zones a zone defines the general nature if it is a gas or dust and the probability of hazardous material being present in an ignitable concentration in the surrounding atmosphere. In north america hazardous areas are classified by the class division system or by a zone system adapted to the iec standards. This level of risk is represented by classifying the hazardous area as zone 0 zone 1 or zone 2 for gas vapour and mist atmospheres or zone 21 or zone 22 for dust atmospheres. In this article we will look at what defines zone 0 zone 1 and zone 2 hazardous area classifications and the considerations for specifying lighting into each area.
The zone numbers used are 20 21 and 22 corresponding to 0 1 and 2 used for gases vapours. It s the ideal choice for vertical surface lighting where harsh and hazardous conditions require high quality reliable illumination. In electrical and safety engineering hazardous locations hazloc pronounced haz lōk are places where fire or explosion hazards may exist. Atmosphere containing a flammable gas a flammable liquid produced vapor or a combustible liquid produced vapor mixed with air that may burn or explode having either a mesg maximum experimental safe gap 1 value less than or equal to 0 45 mm or a mic minimum igniting current 2 ratio less than or equal.
Electrical equipment installed in such locations could provide an ignition source due to electrical arcing or high temperature. Class ii hazardous locations are areas where combustible dust rather than gases or liquids may be present in varying hazardous concentrations. Appleton light fixtures are designed to withstand the harshest conditions and operate across your facilities without incident.
