Safeguarding Zone 2 Operations: How TLS 20ft Positive Pressure Ex-Proof Containers Work on Oil & Gas Platforms

​Introduction
Oil & gas platforms operate in some of the most challenging and hazardous environments on Earth. In Zone 2 classified areas, there's a potential risk of explosive atmospheres forming due to the presence of flammable gases or vapors. To ensure the safety of personnel and critical equipment, specialized solutions like TLS 20ft positive pressure ex-proof containers are essential. In this blog post, we'll dive into how these containers work to safeguard operations on oil & gas platforms.
 
Understanding Zone 2 Environments
Zone 2 areas are those where explosive atmospheres are not likely to occur in normal operation but could occur for short periods due to abnormal situations like leaks or equipment malfunctions. These zones demand equipment that prevents ignition sources from triggering explosions.
 
TLS 20ft Positive Pressure Ex-Proof Containers: The Solution
TLS 20ft positive pressure ex-proof containers are designed to provide a safe, controlled environment for housing electrical and electronic equipment in Zone 2 hazardous areas. They achieve this through a combination of features:
 
1. Robust Construction

• Ex-proof Enclosure: The container's shell is built from heavy-duty steel or other robust materials to withstand harsh offshore conditions and potential impacts. It's designed to contain any internal explosion, preventing it from propagating to the external environment.
• Flameproof Joints: Flanges and other joints are meticulously designed to prevent flames from escaping the enclosure even in the event of an internal explosion.

 
2. Positive Pressure System

• Air Pressurization: The container is continuously pressurized with clean, filtered air. This positive pressure ensures that any potential flammable gases or vapors are kept out of the enclosure.
• Pressure Monitoring: Sophisticated sensors constantly monitor the internal pressure. If the pressure drops below a safe threshold, alarms are triggered, and automatic shutdown systems can be activated to prevent any ignition sources from operating.

 
3. Purging and Ventilation

• Initial Purging: Before equipment is energized, the container undergoes a purging process to replace any internal air with clean, inert gas. This eliminates any potential explosive atmosphere within the enclosure.
• Continuous Ventilation: While in operation, the container is continuously ventilated with clean air to maintain positive pressure and prevent the buildup of heat.

 
4. Electrical Safety

• Ex-certified Components: All electrical and electronic equipment installed within the container must be certified for use in Zone 2 hazardous areas. This ensures they are designed to operate safely without creating ignition sources.
• Cable Glands and Seals: Cable entries and exits are carefully sealed with ex-proof cable glands to prevent any potential ingress of flammable gases or vapors.

 
Benefits of TLS 20ft Positive Pressure Ex-Proof Containers:

• Enhanced Safety: These containers significantly reduce the risk of explosions and fires in Zone 2 environments, protecting both personnel and valuable equipment.
• Operational Continuity: By housing critical equipment in a safe environment, they ensure uninterrupted operations even in the face of potential hazards.
• Regulatory Compliance: TLS containers are designed and certified to IEC60079-13 which can meet stringent international safety standards for Zone 2 hazardous areas.

 
Conclusion:
TLS 20ft positive pressure ex-proof containers play a vital role in maintaining safety and operational efficiency on oil & gas platforms in Zone 2 environments. Their robust construction, positive pressure system, and other safety features make them an indispensable solution for protecting critical equipment and personnel in these challenging conditions.
