GeneralBefore You BuyFixtures and FittingsInstallationGeneral
How Do You Determine If a Light Is Explosion Proof?
In the USA, the light requires a certification to UL844 standard. Beyond that, you have to determine what certification applies – Class 1 Division 1 and Class 1 Division 2 are the most common.
There are other certifications – like ATEX, that apply to other countries. In the USA, Canada and locations near here, make sure it is UL844 certified.
What Is the Difference Between Flame Proof and Explosion Proof LED Lights?
A flame proof light is one that’s built with materials that inhibit flames. An explosion proof light fixture is designed to operate in a explosive environment. Never use a flame proof light in place of an explosion proof light. Only certified Hazardous Lighting Fixtures will work in these types of environments.
What LED Explosion Proof High Bay Do You Recommend?
You need to choose between Class 1 Division 1 and Class 1 Division 2. Once you have that determined, then you must decide how much light you need. Creating a lighting plan will help match your lighting needs with the right fixture. This completely eliminates any guesswork from the equation.
Are All LED Lights Explosion Proof?
Not all LED lights are explosion proof. The fixture tested under the UL844 certification meet explosion proof requirements. Do not confuse vapor proof with explosion proof, they are not the same thing. Never use vapor tight fixtures in an environment where hazardous location lighting is required.
What Are Intrinsically Safe Lights?
Intrinsically safe lighting fixtures differ from explosion proof lighting fixtures. They’re designed so they cannot create an explosion or spark. For the most part, they tend to be low power, low voltage lighting and often are battery-powered.
What is Blast Proof Lighting?
Blast proof lighting is just another way of saying “Explosion Proof Lighting”. The concept of “Blast Proof” is a light designed not to create a “Blast”, or “Explosion”.
Why Would an LED Bulb Explode?
An LED bulb, by itself, should never explode. But if this bulb creates a spark in an explosive environment, it could cause an explosion. An explosion created inside an explosion proof light fixture will never escape the fixture.
What is Hazardous Location Lighting?
LED Hazardous Location Lighting is a category of lights designed to work in explosive environments. The environments can be either ones where gas or dust is present. They’re designed not to cause a spark that turns into an explosion in these areas.
Are LED Hazardous Location Lighting Fixtures the Same As Explosion Proof Lights?
Yes, hazardous location lighting is the same thing as explosion proof lights. There are areas that are hazardous and non explosive. In those cases, our standard lines of LED products would work there.
A few exceptions would be in areas where food preparation or high temperature areas. In those cases, use food safe lights and high temperature lights.
BEFORE YOU BUY
How Does LED Ex-proof Lighting Work?
The light’s designed to prohibit an explosion starting within the fixture from escaping. It is not vapor tight, as some may think. The light’s design includes a series of channels. These channels cause hot gas or flames that might start inside the fixture to cool down. By the time it leaves the fixture, it’s been de-fused.
When Does It Make Sense to Use Hazardous Location Lights?
There are rules and regulations that mandate the use of these lights. They’re used in any environment, indoors or outdoors, where a spark from a light could cause an explosion. A refinery or underground mine are good examples where to use these lights.
Where Are Your LED Ex-proof Lighting Fixtures Manufactured?
Our LED Explosion Proof Lighting fixtures are manufactured in our overseas facilities. We stock these fixtures in the USA.
Do you need BAA / TAA (Buy America Act) certified fixtures? We can also supply BAA / TAA versions of some of our explosion proof fixtures. Our BAA versions usually carry a 4-week production lead-time.
What Temperatures Can Explosion Proof Lighting Handle?
Our temperature rating for explosion proof lights are between 121F to 149F (up to 185F for Exit Signs). We state on each product what the upper operating temperature is.
What are some of the non-standard Explosion Proof Lights you carry and offer?
Besides the typical high and low bay fixtures, we have
Explosion Proof Emergency Lights
Explosion Proof Flood LightsAre Explosion Proof Lights Shatter-proof?
Our explosion proof lights are all IK10 rated. This is the highest impact rating impact rating that’s available. All our fixtures come with a tempered glass lens that is IK10 rated-shatter proof.
What’s the Difference Between Explosion Proof Low Bays and High Bays?
The only real difference is low bay fixtures are lower powered versions of high bay products. You would install low bay fixtures at heights under 20 feet. High power high bay fixtures would make the area too bright. Using a lower powered fixture makes most sense in these applications.
What are the Types of Explosion Proof Lighting?
Our explosion proof lights are also IP65 or higher rated, so you can use them in both indoors or outdoors. Our lights are adaptable. They can replace many existing metal halide and fluorescent fixtures including:
High Bays and Low Bays
Linear Strip Fixture
Explosion Proof LED Flood Lights
Jelly Jars
Temporary Work Lights
Exit SignsFIXTURES AND FITTINGS
Class I Locations: Flammable Gases, Vapors or Liquids
Class I are areas where vapors and / or gases that can ignite and are present in enough quantity to create an explosion. Vapors are gases present over a liquid material under normal conditions. But they may emit gases that may be flammable.
Division 1
Division 1 are areas where the flammable vapors or gases are present all or most of the time under normal operating conditions.
Division 2
Division 2 are areas where ignitable gases or vapors are not present under normal operating conditions. Or they are areas next to Class I, Division 1 locations where barriers, walls or doors do not exist.
Groups of Class 1 Locations
There are 4 groups defined for Class 1 Locations and represent the type of gas or vapor.
Group A: Acetylene
Group B: Hydrogen
Group C: Ethylene
Group D: Gasoline / PropaneClass II Locations: Combustible Dusts And Hazardous Substances
These are locations that are hazardous because of the presence of combustible dust. The dust must be present in large enough quantities to create an explosion or fire. To be classified as dust, the material must be 420 microns (0.420 mm) or smaller.
Division 1
This is similar to Class 1 Division 1. These locations contain combustible dust which is suspended in the air in quantities which can produce an explosion if ignited under normal operating conditions.
Division 2
This is similar to Class 1 Division 2. These location do not have combustible dust under normal operating conditions. However, there are times where this area may accumulate dust in quantities large enough that when ignited causes an explosion.
Groups of Class 2 Locations
There are 3 groups defined for Class 2 Locations and represent the type of dust or combustible particle.
Group E: Electrical-conductive dust
Group F: Carbonaceous dust
Group G: Agricultural and polymer dustClass III Locations: Ignitable Flyings and Fibers
A Class III location are areas that have the presence of ignitable fibers or flyings. Its important to note that these fibers or flyings are not likely to be in suspension during normal operating conditions. These are conditions that sometimes happen, but not always happen.
Division 1
Class III, Division 1 locations have equipment that produces the ignitable fibers or flyings. This location has concentrations of ignitable fibers or flyings that exists all or some of the time under normal operating conditions.
Division 2
Class III, Division 2 locations outside of the manufacturing area that are exposed to ignitable fibers or flyings. This location has concentrations of ignitable fibers or flyings that does typically does not exist under normal operating conditions.
Groups of Class III Locations
There are no groups in Class III locations.
What Are the Best Applications for LED Explosion Proof Lighting?
Hazardous location LED lighting can replace, 1 for 1, metal halide and fluorescent fixtures. in indoor and outdoor explosive locations. You can use a explosion proof lighting fixture indoors or outdoors. You can use them in new or existing facilities for the following applications:
Chemical processing plants
Aircraft maintenance areas
Enclosed fueling stations
Paint spray booths
Offshore oil and gas rigs
Chemical storage units
Ship tanks
Refineries
Oil and gas storage
Grain silosWhat’s the Difference Between Class Division 1 and Class 1 Division 2?
Flammable gases, vapors, and liquids and are present at all times: use Class 1 Division 1
Flammable gases, vapors, and liquids and are present some of the times: use Class 1 Division 2
Can You Substitute a Class 1 Fixture for Classes 2 or 3?
No. Unlike divisions described above, you cannot swap an explosion proof lighting fixture among classes. It is either rated for the Class you need or it isn’t.
Can you use a Division 1 Fixture of a class in a Division 2 Area of the Same Class?
Yes, that assumes that both have the same grouping certification. For example, C1D1, Group C can substitute in C1D2, Group C areas.
What’s the Difference Between Class 1, Class 2 and Class 3?
Class 1: Gases – Areas in which flammable gases or vapors are present.
Class 2: Dust – Areas in which combustible dust suspends in the air or can accumulate on equipment.
Class 3: Fibers Areas in which ignitable fibers are present.INSTALLATION
What Are the Mounting Bracket Options?
The main and most common mounting options available are:
Pendant – the wiring runs through the pendant into a junction box.
Trunnion / Yoke Mount – wired with flex pipe to a junction box.There are some custom mounts that are also available:
Slip Fitter / Pipe Mount – For pole mounting – square fixture
Surface Mount Arm – for wall mounting
Stanchion Mounting – for pole mounting – round fixtureHow Do I Replace an Explosion Proof Light with LED?
Our lights can replace metal halide and fluorescent lighting 1 for 1. It should be as simple as removing the existing light and replacing it with the new light. We recommend using a certified electrician. Make sure they’re familiar with explosion proof lighting when replacing these fixtures.
Do your Fixtures Come with a Whip or Cord?
It does not. Everything inside these areas needs to be explosion rated. This includes junction boxes and conduit that supplies power to the fixture. Unlike a normal high bay, an exposed power cord/whip does not make sense.
