Liquefied natural gas facilities handle large quantities of combustible material in an environment filled with piping, process equipment, electrical systems, vehicles, maintenance operations, and other potential ignition sources. When natural gas or LNG escapes containment and ignites, workers may be exposed to intense heat with little warning.
An LNG fire can develop in several ways. A release may ignite almost immediately at the source. Escaping gas may travel before reaching an ignition source. LNG may collect and burn as a pool fire. Equipment or surrounding materials may also catch fire and create additional hazards after the initial event.
These incidents can cause devastating burn injuries as well as respiratory damage, blast trauma, and other serious harm. Fires represent one of the many hazards capable of causing an LNG plant accident, and determining why a fire occurred often requires examining both the original release and the conditions that allowed ignition.
An LNG plant fire accident lawyer may need to investigate equipment failures, hot work, electrical systems, gas-detection equipment, maintenance history, emergency response, and the actions of multiple contractors working in or around the affected area.
How Fires Can Develop at LNG Facilities
A fire at an LNG facility generally begins with a loss of containment or another source of combustible material.
Natural gas may escape through piping, valves, flanges, compressors, pumps, seals, hoses, or other process equipment. A release may also occur while equipment is being opened, repaired, tested, or placed back into service.
If the released gas encounters an ignition source, fire can spread quickly.
Potential ignition sources may include electrical equipment, hot machinery surfaces, welding and cutting operations, vehicles, static discharge, or sparks generated during maintenance and construction work.
The precise type of fire depends on the circumstances surrounding the release. Some incidents remain localized around leaking equipment. Others may expose much larger areas of a facility.
Flash Fires and Rapid Ignition
One particularly dangerous scenario occurs when gas accumulates or travels through an area before ignition.
A flash fire can occur when a flammable vapor cloud ignites and flame rapidly passes through the combustible mixture.
Workers caught within the affected area may be exposed to extreme heat before they have time to escape. Even when the duration of the fire is relatively short, the thermal exposure can be severe enough to cause deep burns, ignite clothing, and damage the respiratory system.
A flash fire may also ignite nearby equipment or materials, causing secondary fires that continue after the initial vapor cloud has burned.
An LNG fire accident attorney investigating this type of incident may examine where the release began, how the vapor moved through the area, what caused ignition, and whether gas-detection or alarm systems provided adequate warning.
Pool Fires Involving LNG
Liquid LNG released from equipment may collect on the ground or within a containment area.
As the LNG warms, it vaporizes. If combustible vapor above the liquid ignites, a pool fire can develop.
Pool fires can generate extremely intense heat. Workers do not necessarily need to come into direct contact with the flames to suffer injury. Radiant heat can cause burns at a distance and may damage nearby equipment or structures.
The heat generated by a significant fire can also complicate emergency response. Workers may be unable to approach valves, shutdown controls, or equipment necessary to isolate the source of the release.
That is one reason facility layout, containment, remote shutdown systems, and emergency planning can become important after a major LNG fire.
Jet Fires From Pressurized Releases
Natural gas escaping from a pressurized system can create another dangerous fire condition.
If the release ignites while gas continues escaping under pressure, the result can resemble a high-intensity flame directed from the failed piping or equipment.
Workers positioned near the release may have little opportunity to move away. The direction of the escaping gas can also expose workers or equipment that would otherwise have been outside the immediate hazard area.
These events may involve failures of piping, valves, flanges, hoses, compressors, or other pressurized components.
An LNG plant fire lawyer may need to determine whether the equipment failed because of corrosion, improper installation, inadequate maintenance, excessive pressure, defective components, or another preventable condition.
Hot Work Can Create an Ignition Source
LNG facilities frequently require welding, cutting, grinding, and other forms of hot work.
These activities are common during construction, repair, expansion, and maintenance. They also create sparks and heat capable of igniting combustible materials or flammable vapors.
A hot work permit should identify the work being performed, evaluate surrounding hazards, and establish appropriate precautions before the job begins.
Depending on the circumstances, those precautions may include atmospheric testing, fire watches, removal of combustible materials, isolation of process equipment, and continued monitoring of conditions.
The permit process should not become a paperwork exercise.
Conditions around industrial equipment can change quickly. A system believed to be isolated may begin leaking. Another contractor may open equipment nearby. Gas can migrate into a work area after hot work has already started.
A serious fire may therefore raise questions about whether the work was properly planned and whether anyone continued evaluating conditions after the job began.
Electrical Sources of Ignition
Modern LNG facilities depend on extensive electrical infrastructure.
Motors, pumps, lighting, switchgear, instrumentation, transformers, control systems, temporary electrical equipment, and other components may operate throughout the site.
Electrical malfunctions can cause fires on their own. Sparks or arcs can also ignite a flammable gas release.
Construction and maintenance activities can increase these risks because temporary and permanent electrical systems may be operating close to one another. Damaged wiring, improperly installed equipment, inadequate maintenance, or failures involving electrical isolation can create dangerous conditions.
When an LNG fire begins near electrical equipment, the investigation may need to determine whether the electrical failure caused the original event or simply became the ignition source for a gas release originating elsewhere.
Maintenance and Isolation Failures
Many industrial fires occur while workers are performing maintenance.
Repair work may require a line to be opened, a valve removed, a pump disconnected, or equipment taken apart. Before that work begins, hazardous energy and process material should be properly isolated.
Failure to follow appropriate lockout/tagout practices can expose workers to unexpected energy or process flow.
Even after equipment is shut down, residual gas or pressure may remain.
A worker opening a line believed to be empty can suddenly be exposed to combustible material. If a nearby ignition source is present, an ordinary maintenance task can become a catastrophic fire.
An LNG plant accident attorney may examine permits, isolation procedures, valve lineups, atmospheric testing, shift records, and communications between operations and maintenance personnel.
Fires During Startup and Commissioning
Startup and commissioning can create conditions different from normal operations.
Newly installed equipment may be energized for the first time. Gas may be introduced into systems that were previously empty. Valves and controls may be tested. Temporary construction conditions may still exist nearby.
At the same time, numerous contractors may remain on site.
These changing conditions can create risks when workers are not aware that equipment has become energized, pressurized, or placed into service.
A fire occurring during commissioning may therefore involve failures of communication as much as failures of equipment.
Determining what happened may require reviewing startup procedures, control-room data, work permits, contractor coordination, and the sequence in which systems were placed into operation.
Burn Injuries From LNG Fires
Industrial fires can cause severe burn injuries.
The seriousness of a burn depends on factors such as temperature, duration of exposure, the percentage of the body affected, and the depth of tissue damage.
Some workers suffer burns to exposed skin. Others may have clothing ignite or become trapped near a continuing fire.
Severe burns can damage skin, muscle, nerves, and underlying tissue. Treatment may require hospitalization, repeated surgeries, skin grafts, wound care, and rehabilitation.
Victims may also experience infections, chronic pain, mobility limitations, and permanent scarring and disfigurement.
An LNG plant fire accident lawyer evaluating a burn case should consider not only the initial hospitalization but also the long-term physical and psychological consequences of the injury.
Inhalation Injuries During LNG Fires
A worker can suffer serious injuries during a fire without sustaining extensive external burns.
Hot gases, smoke, combustion products, and chemicals released during an industrial fire can damage the respiratory system.
A worker may suffer chemical inhalation injuries after breathing hazardous substances generated or released during the incident.
Heat itself can injure the airway. Smoke can reduce visibility and make escape more difficult. Respiratory symptoms may also worsen after the worker has left the immediate scene.
That is why workers exposed to a significant industrial fire may require medical evaluation even when their external burns appear limited.
Other Injuries Caused by LNG Fires
Fire is often only one part of the accident.
Workers attempting to escape may fall from elevated structures, trip over equipment, or collide with objects in low-visibility conditions. Others may be struck by damaged equipment or debris.
A serious incident may cause internal bleeding, fractures, spinal injuries, hearing damage, or traumatic brain injury.
Some workers may suffer multiple injury mechanisms at the same time.
For example, a worker may sustain thermal burns, inhale smoke, and suffer orthopedic injuries while escaping the area.
That combination can make treatment and recovery significantly more complicated.
Emergency Shutdown and Fire Protection Systems
LNG facilities use various systems intended to limit the consequences of a release or fire.
Gas detectors may identify combustible material in the atmosphere. Alarms may warn workers. Emergency shutdown systems may isolate portions of the process. Fire protection systems may help control or limit fire spread.
When a major fire occurs, investigators may need to determine whether these systems functioned properly.
Relevant questions may include when the first gas alarm occurred, whether workers received adequate warning, whether shutdown equipment activated, and whether the system successfully isolated the release.
The investigation may also examine whether fire protection equipment had been inspected, tested, and maintained.
A failure involving a critical safety device can turn a manageable incident into a much larger emergency.
Multiple Companies May Share Responsibility
LNG facilities frequently rely on contractors and subcontractors for specialized work.
An owner or operator may control the process equipment while another company performs maintenance. A construction contractor may oversee a project while subcontractors handle welding, electrical work, insulation, scaffolding, or mechanical repairs.
If one contractor creates a dangerous condition that injures another company’s employee, the incident may involve third-party liability.
An LNG plant fire accident attorney may need to determine who controlled the equipment, who authorized the work, who knew about the gas release, and which company was responsible for eliminating potential ignition sources.
Written contracts can be important, but actual jobsite practices may be equally significant in determining who exercised control.
Preserving Evidence After an LNG Fire
Fire scenes can change quickly.
Emergency response may require equipment to be moved or damaged components to be removed. Repairs may begin soon after the area is declared safe.
Important evidence may include process data, alarm records, gas-detector readings, surveillance footage, maintenance history, work permits, photographs, inspection records, electronic communications, and witness statements.
The failed equipment itself may also be critical.
Engineers, fire investigators, metallurgists, electrical specialists, or another expert witness may need to inspect damaged components before they are repaired, altered, or discarded.
Prompt preservation is particularly important when electronic systems automatically overwrite older data.
Long-Term Consequences of Severe Burn Injuries
The effects of an industrial burn injury can extend far beyond the initial emergency treatment.
Workers with severe burns may undergo multiple surgical procedures and lengthy rehabilitation. Skin grafting, reconstructive surgery, scar treatment, occupational therapy, and pain management may continue for years.
Some victims may require substantial future medical care.
Permanent scarring, limited range of motion, nerve damage, respiratory problems, and chronic pain can also interfere with a worker’s ability to return to physically demanding employment.
These injuries may qualify as serious and catastrophic injuries when they permanently alter a person’s health, appearance, independence, or ability to work.
Fatal fires may also give surviving family members grounds to pursue a wrongful death claim against responsible parties.
