How to choose the right industrial explosion proof lighting

From: www.njzlighting.com Jun 19, 2017
Using improper fixtures in a hazardous location can cause an explosion by arcing and igniting any flammable gases or dust particles present in the air. Examples of hazardous locations include grain elevators, oil refineries,and chemical plants.If you are currently running or working with a facility which requires these explosion proof light fixtures, how to choose the right industrial explosion proof lighting?
 
1.Choose the best lighting technology.

LED lighting that is explosion-proof also contains different design elements from traditional explosion-proof lighting, starting with the most obvious: traditional explosion-proof lighting usually relies upon fluorescent or incandescent bulbs.To give you a little bit of insight on industrial LEDs, here are some of the reasons why companies of all sorts are converting to LED:
Energy reductions up to 75%
Increased lifespan by 2-3+ times
Better quality of light (no flickering or buzzing).
 
2.Pay attention to the classification.

Currently, there are a handful of classifications for explosion-proof LED lighting. Ratings are used by engineers and architects to determine where the light should be used and under what conditions. The rating system is as follows:
  • Class I, Div.1:Where ignitable concentrations of flammable gases, vapors or liquids are present continuously or frequently within the atmosphere under normal operation conditions.
  • Class I, Div.2:Where ignitable concentrations of flammable gases, vapors, or liquids are present within the atmosphere under abnormal operating conditions.
  • Class II, Div.1:Where ignitable concentrations of combustible dusts are present within the atmosphere under normal operation conditions.
  • Class II, Div.2:Where ignitable concentrations of combustible dust are present within the atmosphere under abnormal operating conditions.
  • Class III, Div.1:Where easily ignitable fibers or materials producing combustible flyings are present within the atmosphere under normal operation conditions.
  • Class III, Div.2:Where easily ignitable fibers or materials producing combustible flyings are present within the atmosphere under abnormal operating conditions.
  •  
NJZ Lighting explained that lights will always have to meet the classification requirement, otherwise they will not meet compliance standards and regulations. 
 
3.Cost Saving with DLC qualified fixtures.

The advice of NJZ Lighting is this; to get the best value buy only DLC qualified fixtures. If you don’t, you may actually end up spending more upfront (by not getting any rebates) as well as more energy usage overtime, due to a less efficient build.
