Marine and offshore facilities can contain areas where flammable gases, vapours or combustible substances may be present.
In these environments, electrical equipment must be carefully selected because an electrical spark, arc or excessive heat can create a serious ignition risk.
Explosion-proof electrical equipment is designed specifically for hazardous-area applications. Depending on the equipment and certification, it can help prevent an internal ignition source from igniting the surrounding atmosphere.
For ship operators, offshore contractors and industrial facilities, selecting properly certified equipment is an important part of hazardous-area safety.
What Is Explosion-Proof Electrical Equipment?
Explosion-proof electrical equipment is designed and constructed for use in environments where explosive atmospheres may exist.
Depending on its protection method and certification, equipment can be designed to contain an internal explosion, prevent ignition or provide other forms of protection appropriate to the hazardous area.
Products can include:
- Explosion-proof LED lights
- Explosion-proof floodlights
- Explosion-proof ceiling lights
- Explosion-proof warning lights
- Explosion-proof switches
- Explosion-proof electrical fittings
- Hazardous-area accessories
Oceanic GMS supplies explosion-proof lighting and electrical products for marine, offshore and industrial applications.
Where Is Explosion-Proof Equipment Used?
Hazardous-area electrical equipment can be required in locations such as:
- Oil and gas facilities
- Offshore platforms
- Tankers
- Refineries
- Petrochemical plants
- Chemical processing facilities
- Fuel storage areas
- Marine engine rooms
- Pump rooms
- Hazardous cargo areas
The exact equipment requirement depends on the hazardous-area classification and project specifications.
Why Certification Matters
One of the most important considerations when selecting hazardous-area equipment is certification.
Common certification systems and standards include:
- ATEX
- IECEx
- CE
- Applicable IEC standards
- Equipment-specific hazardous-area classifications
ATEX and IECEx certifications provide important information about the suitability of equipment for specified hazardous environments.
However, certification should not be viewed in isolation.
The complete equipment marking and project requirements should be checked before installation.
Understanding Hazardous Zones
Hazardous areas can be classified according to the likelihood and duration of an explosive atmosphere being present.
For gas and vapour environments, Zone 1 and Zone 2 are commonly encountered classifications.
Zone 1 generally refers to an area where an explosive gas atmosphere is likely to occur during normal operation.
Zone 2 generally refers to an area where an explosive gas atmosphere is not expected during normal operation but may occur for a short period if it does.
The equipment selected must be suitable for the specific hazardous area.
Why Ordinary Electrical Equipment Can Be Dangerous
Standard electrical equipment may contain components that produce:
- Sparks
- Electrical arcs
- High surface temperatures
- Switching contacts
- Hot components
In a normal environment, these may not create an ignition concern.
In an area containing flammable gases or vapours, however, an ignition source can create a serious safety hazard.
This is why appropriately certified hazardous-area equipment is essential.
Explosion-Proof LED Lighting
LED technology is increasingly used for hazardous-area lighting.
Explosion-proof LED fixtures can provide:
- High illumination
- Lower energy consumption
- Long operating life
- Reduced maintenance
- Low heat output
- Reliable operation
Oceanic GMS supplies ATEX and IECEx-certified explosion-proof LED lighting for applications including oil and gas facilities, offshore platforms, refineries, chemical plants and marine environments.
Protection Against Harsh Marine Conditions
Hazardous-area equipment used offshore or onboard ships may face additional environmental challenges.
These can include:
- Saltwater exposure
- High humidity
- Corrosion
- Vibration
- Temperature variations
- Mechanical impact
For this reason, environmental protection is also important.
Depending on the product, Oceanic GMS offers explosion-proof lighting with IP66 or IP67 protection and marine-grade construction.
Explosion-Proof Warning and Signal Lights
Visual warning systems can also be important in hazardous environments.
Explosion-proof warning and signal lights can be used where high-visibility visual alerts are required.
Oceanic GMS supplies explosion-proof warning and signal lights with features including IP66 protection and hazardous-area certifications such as IECEx and ATEX, depending on the product.
How to Select the Right Equipment
Before purchasing explosion-proof electrical equipment, consider:
1. Hazardous-Area Classification
Identify the applicable zone and environment.
2. Gas or Dust Group
Determine the type of hazardous atmosphere present.
3. Temperature Class
Check the required temperature classification for the application.
4. Certification
Verify that the product certification matches the project requirements.
5. IP Rating
Consider the level of protection needed against water and dust.
6. Operating Temperature
Ensure the equipment can operate within the environmental temperature range.
7. Installation Requirements
Check cable entry, mounting method, voltage and other installation specifications.
8. Marine Conditions
For marine applications, consider corrosion, vibration, humidity and saltwater exposure.
Why Work With a Specialist Supplier?
Hazardous-area electrical equipment should not be selected solely based on price or appearance.
A specialist supplier can help identify suitable products based on:
- Application
- Hazardous-area classification
- Certification
- Electrical specifications
- Environmental conditions
- Installation requirements
- Project requirements
This can help reduce the risk of selecting equipment that is unsuitable for the intended environment.
