Jain Chem Ltd.
Specifying C1D2 Non-Metallic Linear LED Lighting with Emergency Backup

Industry: Chemical Processing

Location: South Carolina

Challenge: A chemical processing facility required hazardous location lighting appropriate for Class I Division 2 areas, with durable construction for chemical exposure and emergency illumination to support safe egress during power loss.

Solution: We supplied non-metallic linear LED fixtures rated for Class I Division 2 (C1D2), including fixtures equipped with emergency battery backup for critical areas.

The Challenge: Hazardous Location Lighting That Also Survives Chemical Exposure

Jain Chem Ltd. is a chemical processing operation located in Taylors, South Carolina. The facility required hazardous location lighting for its operations, specifically linear LED fixtures rated for Class I Division 2 environments.

In chemical processing, lighting selection has to solve more than visibility. Facilities often face corrosive vapors, regular cleaning, and the reality that abnormal conditions can occur. Lighting must be appropriate for the classified area, durable in the operating environment, and dependable when the facility needs it most.

In addition to standard hazardous area lighting needs, the project required a portion of the fixtures to include emergency battery backup. In a power outage, personnel still need to safely navigate to exits and manage process conditions without being plunged into darkness in an environment where flammable vapors could be present under abnormal conditions.

Jain Chem needed the correct combination of hazardous location rated linear fixtures and emergency backup units, without relying on general industrial products that are not designed for classified areas or chemical exposure.

Why Standard Industrial Fixtures Were Not Suitable for This Environment

In a typical warehouse, a standard industrial fixture might be acceptable. In chemical processing and classified areas, the wrong lighting choice can create both reliability problems and safety risk.

• Classified areas require rated equipment Standard industrial fixtures are not appropriate for Class I Division 2 hazardous locations unless they are specifically rated and installed for the classification.

• Chemical exposure accelerates corrosion Vapors and cleaning agents can degrade housings, fasteners, and seals over time.

• Emergency visibility is a safety requirement If power fails, personnel must still see clearly to move safely and manage conditions.

• Fixture format impacts usable light In processing areas, even illumination across work zones and walkways often matters more than “high ceiling brightness.”
  

Because of these constraints, Jain Chem needed a lighting solution designed for both the classification requirement and the realities of chemical processing.

The Solution

We supplied hazardous location lighting suited to a chemical processing facility, specifically:

• Non-metallic linear LED fixtures rated for Class I Division 2 (C1D2)

• Washdown rated fixtures that will hold up to the chemical cleaning and laboratory exposure under normal operations.

• C1D2-rated linear fixtures equipped with emergency battery backup for areas requiring emergency illumination
  

This approach provided durable, application-appropriate lighting while supporting emergency visibility during power loss.

Why C1D2 Non-Metallic Linear Fixtures Were the Right Choice

• Correct hazardous location rating Class I Division 2 is commonly used in chemical processing where flammable vapors are not normally present under standard operations but could occur under abnormal conditions. Selecting fixtures rated for C1D2 aligns equipment selection with the site’s classification requirements.

• Non-metallic construction resists chemical corrosion Non-metallic housings can provide better resistance to chemical vapors and cleaning agents and reduce long-term corrosion concerns that can affect metal fixtures. Any metallic hardware is stainless steel for chemical and corrosion resistance.

• Reduced galvanic corrosion concerns. Over time, metal housings and mixed-metal hardware can be affected by galvanic corrosion in harsh environments. Chemical exposure eats away at any protective finish coatings. Non-metallic construction can reduce that risk.

• Linear format supports practical task visibility Linear fixtures often provide more even illumination across process equipment, work surfaces, and walkways compared to point-source high-bay styles, which supports safer movement and task work.

• Emergency battery backup supports safe egress In a power failure, emergency illumination helps personnel navigate to exits and maintain situational awareness while managing process conditions.

The Results

The facility received a hazardous location lighting solution aligned to both the classification requirement and the chemical processing environment.

• C1D2 hazardous location requirement addressed Fixtures were selected for Class I Division 2 areas where flammable vapors may be present under abnormal conditions.

• Improved durability for chemical exposure Non-metallic construction supported corrosion resistance in the presence of vapors and cleaning agents.

• Better task-focused visibility Linear fixtures supported even illumination across work zones and walkways.

• Emergency illumination capability added Battery backup fixtures supported safer navigation and response during outages.
  

The outcome was a lighting package designed for chemical processing realities: classification-driven selection, durability for chemical exposure, and dependable emergency visibility.

Why C1D2 Is Common in Chemical Processing Facilities

Chemical processing environments frequently include classified areas where vapor hazards are possible, even if they are not present during normal operation.

• Abnormal conditions can introduce vapors Leaks, maintenance events, equipment failures, or upset conditions can create flammable vapor presence.

• Division 2 reflects “not normally present” Class I Division 2 is typically used when ignitable concentrations are not expected during standard operations, but could occur under abnormal conditions.

• Division 1 is a different risk profile Class I Division 1 applies when ignitable concentrations can exist under normal operating conditions or frequently due to maintenance, repair, or leakage.

• The classification drives equipment selection In classified areas, rated equipment is required. The correct rating depends on how the hazard is expected to be present.
  

This is why C1D2-rated lighting is often specified in chemical processing facilities for areas where vapors could be present during abnormal events, not continuously during normal operations. Any chemical processing facility that has the potential for flammable vapors to exist during normal operations require C1D1-rated lighting and equipment.

Frequently Asked Questions

What is the difference between Class I Division 1 and Class I Division 2?

Class I refers to areas where the hazard involves flammable gases or vapors. Division 1 indicates ignitable concentrations may be present under normal operating conditions. Division 2 indicates ignitable concentrations are not normally present, but could occur under abnormal conditions such as leaks or equipment failure.

Why is non-metallic construction useful in chemical processing lighting?

Non-metallic construction can improve corrosion resistance in the presence of chemical vapors and cleaning agents. It can also reduce long-term issues associated with galvanic corrosion that can affect metal housings and hardware.

Why are linear fixtures often preferred over round high-bay fixtures in processing areas?

Linear fixtures can provide more even illumination across work surfaces, process equipment, and walkways, which supports practical task visibility. In many processing areas, uniform light at work height matters more than concentrated output intended for high ceiling spaces.

Why is emergency battery backup important in chemical facilities?

In a power outage, personnel must be able to safely navigate to exits and maintain visibility while managing process conditions. Emergency backup lighting supports safe movement and response when normal power is unavailable.

Do hazardous location fixtures remove the need for safe installation practices?

No. Hazardous location equipment must be installed by qualified personnel in accordance with applicable electrical codes and the manufacturer’s instructions. Fixture rating is one part of a safe classified-area lighting system.
