Inline Buyer Q&A
What information is needed to select explosion-proof lighting for an oil and gas facility?
Start with the hazardous-location classification for each area where lighting will be installed.
Important information can include:
- Class and Division or Zone
- Gas or vapor group
- Temperature code
- Ambient temperature
- Required certifications
- Fixture type
- Mounting height and location
- Voltage
- Required illumination
- Environmental exposure
- Corrosion or marine conditions
- Existing fixtures for retrofit projects
- Facility drawings or classified-area documentation
Different areas of the same oil and gas facility can have different requirements, so equipment should be selected for the specific installation location.
Can the same explosion-proof fixture be used throughout a refinery or processing facility?
Not automatically.
Process units, tank areas, loading locations, compressor areas, maintenance spaces, walkways, and other portions of a facility can have different hazardous classifications and operating conditions.
Fixture certification, gas group, temperature code, ambient rating, environmental characteristics, output, and distribution should be matched to each application.
How do I choose between explosion-proof high bays, floodlights, and linear fixtures?
Fixture type should be selected according to the area and task being illuminated.
High bays can be appropriate for elevated mounting in industrial structures and processing buildings. Floodlights provide directional illumination for equipment, work areas, yards, and other exterior or industrial spaces. Linear fixtures can be useful where elongated light distribution or lower-profile mounting is beneficial.
Regardless of fixture type, the luminaire must be suitable for the hazardous-location classification where it will be installed.
Can existing HID or fluorescent fixtures be replaced one-for-one with hazardous-location LED fixtures?
Potentially, but one-for-one replacement should not be assumed.
The proposed LED fixture should be evaluated for hazardous-location markings, light output, optical distribution, mounting, voltage, ambient temperature, environmental exposure, and required illumination.
A photometric layout can help determine whether existing fixture locations remain appropriate.
What environmental conditions should be considered in addition to the hazardous classification?
Oil and gas facilities can expose lighting equipment to conditions such as:
- Corrosive atmospheres
- Salt and marine exposure
- Moisture
- Dust
- Vibration
- Extreme temperatures
- Wind
- Chemicals
- Washdown or cleaning processes
Hazardous-location certification does not automatically establish suitability for every environmental condition. Construction, materials, finishes, ingress protection, and other ratings should also be evaluated.
Should larger oil and gas projects use a photometric lighting plan?
For larger or more complex facilities, photometric analysis can help evaluate fixture quantity, placement, illumination, distribution, and uniformity.
Photometric performance and hazardous-location suitability are separate considerations. A fixture must satisfy the classified-location requirements regardless of its lighting performance.
Specify Lighting for Each Classified Area of the Facility
Oil and gas lighting projects require more than selecting an “explosion-proof” fixture.
Class, Division or Zone, gas group, temperature code, ambient temperature, fixture type, environmental exposure, mounting, photometric performance, and required certifications should all be considered before equipment is specified.
Our lighting specialists can help evaluate hazardous-location LED lighting for refineries, petrochemical facilities, drilling operations, production sites, fuel terminals, compressor stations, tank farms, processing facilities, and other oil and gas environments.

Frequently Asked Questions About Explosion-Proof Lighting for Oil & Gas Facilities
Why is explosion-proof or hazardous-location lighting used in oil and gas facilities?
Certain areas of oil and gas facilities can contain flammable gases or vapors capable of creating an ignition hazard.
Electrical equipment installed in classified locations must be suitable for those conditions.
Properly rated hazardous-location lighting is designed and certified to address specified ignition hazards while providing the illumination required for facility operations.
Does every area of an oil and gas facility require explosion-proof lighting?
No.
Hazardous-location classifications can vary throughout a facility.
Some areas may be Class 1 Division 1, others Class 1 Division 2 or an applicable Zone classification, and other locations may be unclassified.
The classification of the specific fixture location should determine the required equipment.
What hazardous classifications are commonly encountered in oil and gas facilities?
Depending on the facility, jurisdiction, and classification system, oil and gas projects can include Class 1 Division 1, Class 1 Division 2, and corresponding Zone-system classifications.
The actual classification should come from the facility’s hazardous-area assessment or project documentation rather than being inferred solely from the type of operation.
What is the difference between Class 1 Division 1 and Division 2 in an oil and gas facility?
Both classifications involve flammable gases or vapors.
Division 1 generally applies where ignitable concentrations may exist under normal operating conditions or under other conditions included in the applicable Division 1 definition.
Division 2 generally applies where ignitable concentrations are not normally present during normal operation but may occur under specified abnormal conditions, or where other Division 2 conditions apply.
The actual classified-area documentation should determine equipment selection.
Are LED fixtures suitable for hazardous oil and gas environments?
Yes, when the complete LED luminaire is properly rated and certified for the applicable hazardous location.
LED fixtures can offer benefits such as energy efficiency, instant-on operation, directional optical control, and potentially reduced maintenance compared with some older lighting technologies.
LED technology alone does not make a fixture suitable for a hazardous location.
What certifications and standards are important for oil and gas lighting?
Requirements depend on the location, jurisdiction, classification system, and project specification.
In North America, applicable equipment may be listed or certified under standards such as UL 844 or corresponding recognized hazardous-location standards.
IECEx and ATEX are commonly encountered on international hazardous-area projects.
The NEC establishes electrical classification and installation requirements in the United States; it is not a product certification.
NEMA enclosure types, IP ratings, corrosion ratings, and marine-related requirements address other equipment or environmental characteristics and should not be treated as substitutes for hazardous-location certification.
What types of explosion-proof fixtures are used in refineries?
Depending on the application, hazardous-location lighting can include:
- High bays
- Floodlights
- Linear fixtures
- Low-profile fixtures
- Wall-mounted luminaires
- Emergency lighting
- Portable hazardous-location lighting
- Other specialized fixture configurations
Each fixture must be evaluated for both its lighting function and the classification of the installation location.
What are gas groups and why do they matter in oil and gas facilities?
Under the North American Class/Division system, Class 1 gases and vapors are categorized into Groups A, B, C, and D according to characteristics relevant to hazardous-location equipment.
The fixture should be properly marked for the gas or vapor group applicable to the installation.
A Class 1 marking by itself does not establish suitability for every flammable gas or vapor.
Why is the temperature code important?
A temperature code identifies the maximum surface temperature associated with the equipment under specified conditions.
The fixture’s temperature classification must be appropriate for the ignition characteristics of the hazardous material.
Ambient-temperature limitations should also be reviewed because high or low ambient conditions can affect equipment suitability.
Can a Class 1 Division 2 fixture be installed in a Division 1 area?
Not unless the fixture is also properly rated and marked for the applicable Division 1 location.
Equipment marked only for Division 2 should not be treated as suitable for Division 1.
The complete Class, Division, gas group, temperature code, ambient rating, and other applicable markings should be verified.
Can Class 1 Division 1 fixtures be used in Division 2 areas?
Potentially, when the fixture’s complete markings and characteristics are suitable for the specific Division 2 location.
Division alone is not enough. Gas group, temperature code, ambient rating, environmental characteristics, certifications, and other project requirements still need to be checked.
Are IP66 or IP67 fixtures automatically suitable for oil and gas hazardous locations?
No.
IP ratings describe specified protection against ingress of solids and water.
They do not establish hazardous-location suitability.
A fixture installed in a classified oil and gas environment must carry the appropriate hazardous-location certification and markings in addition to any environmental ratings required for the application.
Are corrosion resistance and explosion-proof certification the same thing?
No.
Hazardous-location certification addresses specified ignition hazards.
Corrosion resistance addresses the ability of fixture materials, finishes, hardware, and other components to withstand particular environmental exposure.
Oil and gas projects may require both characteristics, but they should be evaluated separately.
Can explosion-proof LED fixtures be used offshore?
Potentially.
Offshore installations can add requirements involving marine exposure, salt corrosion, vibration, wind, temperature, environmental ratings, and project-specific standards.
A fixture’s hazardous-location certification alone does not automatically establish suitability for offshore service.
Can hazardous-location LED lighting reduce maintenance in oil and gas facilities?
It can.
LED systems can provide longer service intervals than some traditional lamp-based technologies, which can be valuable where fixtures are difficult to access or maintenance requires operational disruption.
Actual maintenance requirements depend on the complete fixture, driver, operating conditions, environmental exposure, electrical conditions, and installation.
Does hazardous-location certification guarantee adequate illumination?
No.
Certification establishes suitability for specified hazardous-location conditions.
Fixture quantity, placement, output, distribution, glare, illumination, and uniformity must be evaluated separately.
