Lighting in
Hazardous Environments
Different lighting applications present different lighting challenges. Selecting the appropriate luminaire that meets recommended certifications is not only important for properly illuminating the space, but the safety of yourself and others as well.
MARINE ENVIRONMENTS
CONCERNS
Tough conditions in marina, beach, and lake environments
Both fresh and salt water corrodes metal over time (salt being much worse)
Humidity of the ocean air also causes corrosion when metal isn't directly exposed to water
Water ingress can occur when waves and storms cause large amounts of water to hit the luminaire
The above problems increase the risk of premature failure in o luminaire
RECOMMENDATIONS
Look for a non-metallic corrosion-proof luminaire for marine-based projects
Certification: UL Marine Listed
A luminaire needs more than standard wet location features to guarantee protection from moisture in these environmentsCertification: NEMA 4X
Ensures that the luminaire offers superior protection from corrosion and extreme environments
AGRICULTURAL APPLICATIONS
CONCERNS
Grain elevators, hog barns, poultry barns, and other agricultural applications can be at high risk for explosions.
They are enclosed spaces thot are prone to having large amounts of dust in the air
Dust and air in these spaces create a combustible mix, and using the wrong luminaire can provide an ignition source, creating an explosion.
Hog barns have minimal ventilation and corrosive gases, putting them at high risk for explosions and deterioration of materials
Poultry barns are often steam cleaned to remove bacteria and viruses at high pressure. so a hardy luminaire is needed to withstand this
RECOMMENDATIONS
Look for a Hazardous Location rated vapourproof luminaire. This means it is completely sealed to prevent dust and dirt materials from entering and causing a malfunction or explosion.
Certification: UL844 Class II Div 2
Groups F & G
Evaluated and proven to safely withstand explosive dust atmospheres, mitigating the presence of a potential ignition source.Certification: NEMA 4X
Ensures that the luminaire offers superior protection in highly corrosive and extreme environments
MINING APPLlCATIONS
CONCERNS
Tough, compact environments wIth frequent vibrations and temperatures that can reach over 40°C.
Mine explosions are a possibility, with the most common cause being a buildup of methane, a highly combustible gas, with a heat source.
Only a small amount of heat is needed to spark an explosion where methane is present, so a reliable luminaire is essential so that a faulty circuit doesn't cause a chain reaction.
RECOMMENDATIONS
Certification: UL844 Class II Div 2
Groups A, B, C & D
Tested to withstand atmospheres containing flammable gasesCertificatlon: UL844 Class II Div 2
Groups F & G
Evaluated to withstand atmospheres containing explosive dust
