Oil refineries are complex industrial facilities designed to convert crude oil into valuable products like gasoline, diesel, and other essential petrochemical products. Flaring is an integral part of these operations. It is a safety measure to prevent dangerous gases from building up during the refining process.
Although it plays a critical role in maintaining refinery safety, flaring poses several hazards and potential injuries to workers and the surrounding environment. A recent flaring at a Valero refinery in California is highlighting those hazards.
In the article below, the oil refinery injury lawyers at Kherkher Garcia explore the details of oil refinery flaring operations. We also explore the hazards involved, and the injuries that can occur from these processes. As always, you can contact our team directly with any questions about an oil refinery injury.
What Is Oil Refinery Flaring?
Flaring refers to the controlled burning of excess gases and liquids released during the refining process. These gases are typically by-products of chemical reactions and can include volatile organic compounds (VOCs), hydrocarbons, hydrogen sulfide, methane, and carbon dioxide.
Flaring occurs through tall stacks equipped with specialized burners, allowing refineries to release these gases safely into the atmosphere by converting them into less harmful substances through combustion. The flame, which is often seen as a bright burn at the top of these stacks, is a visible indication that excess gas is being disposed of in a controlled manner.
Flaring is essential for maintaining the balance of refinery operations, especially during unplanned equipment shutdowns, maintenance periods, or emergencies.
The Hazards of Flaring Operations
While flaring is a critical safety measure in oil refineries, it also presents a range of hazards. These risks are categorized into two main groups: operational hazards and environmental hazards.
Operational Hazards
Operational hazards occur during the day-to-day activities involved in flaring operations. Workers who are responsible for overseeing the process or working near flare stacks face several dangers, including:
- Explosions and Fires: The combustion of volatile gases can lead to unexpected explosions, especially if the gas-to-air mixture is not properly regulated. Flare stack fires can also spread to nearby equipment and storage tanks, leading to large-scale industrial fires.
- Toxic Gas Exposure: Flaring may not completely eliminate harmful gases like hydrogen sulfide or sulfur dioxide. Workers exposed to these gases may suffer severe respiratory issues, eye irritation, and even long-term health conditions. Inadequate ventilation and poor monitoring can lead to unintentional exposure.
- Heat Stress: The flaring process generates extreme heat, which poses a threat to workers operating nearby. Prolonged exposure to high temperatures can cause heat exhaustion, heatstroke, and burns.
- Equipment Failure: Flare stacks and the associated piping system can deteriorate over time, increasing the risk of equipment malfunction. This can lead to uncontrolled gas release, fire hazards, and additional safety threats for workers on-site.
Environmental Hazards
Flaring also has broader environmental implications that affect not just the refinery workers, but the surrounding community and ecosystem.
- Air Pollution: The gases released during flaring, especially unburnt hydrocarbons and VOCs, contribute to air pollution and can form hazardous compounds like ozone and particulate matter. Long-term exposure to these pollutants can lead to respiratory illnesses and other chronic health conditions in nearby communities.
- Greenhouse Gas Emissions: Methane and carbon dioxide are two primary gases emitted during flaring operations, both of which are potent greenhouse gases that contribute to global warming and climate change.
- Noise Pollution: Flaring operations produce loud, continuous noise from the combustion process, which can lead to hearing damage for workers and disturb surrounding residential areas.
Potential Injuries from Flaring Operations
The hazards associated with flaring operations can lead to a variety of serious injuries for refinery workers and others in the surrounding area.
Burn Injuries
One of the most immediate risks of flaring operations is the potential for burn injuries. Workers exposed to flare stacks or flames can suffer from:
- Thermal Burns: Direct exposure to the high heat generated by the flares can cause severe skin burns. Even short periods of exposure can result in first, second, or third-degree burns.
- Flash Burns: In the event of an explosion or a sudden flare-up, workers may experience flash burns, which result from intense bursts of heat. These burns can damage not only the skin but also the eyes and respiratory system.
- Chemical Burns: Flaring operations may release chemicals that, upon contact with the skin or eyes, can cause chemical burns. This type of burn is particularly dangerous because it can continue to cause tissue damage until the chemical is completely removed or neutralized.
Respiratory Injuries
Inhalation of toxic gases during flaring can lead to significant respiratory injuries and illnesses, including:
- Acute Respiratory Distress: Workers exposed to high concentrations of hydrogen sulfide, sulfur dioxide, or other toxic chemicals can experience difficulty breathing, wheezing, and chest pain. In extreme cases, exposure can lead to respiratory failure or death.
- Chronic Lung Diseases: Long-term exposure to pollutants from flaring, especially fine particulate matter and VOCs, can cause chronic lung diseases such as bronchitis, asthma, and pulmonary fibrosis.
- Oxygen Deprivation: Workers near flare stacks can suffer from oxygen deprivation if the area becomes contaminated with toxic gases that displace breathable air. This can lead to hypoxia, unconsciousness, or even death if the worker is not immediately removed from the area.
Heat-Related Illnesses
The high temperatures associated with flaring operations can also cause:
- Heat Exhaustion: Prolonged exposure to extreme heat may cause workers to experience symptoms of heat exhaustion, including dizziness, fatigue, nausea, and muscle cramps. Without proper intervention, heat exhaustion can progress to heatstroke.
- Heatstroke: If workers are not adequately protected from flare-related heat, they may suffer heatstroke, a life-threatening condition characterized by confusion, seizures, and loss of consciousness. Heatstroke requires immediate medical attention to prevent organ failure or death.
Trauma from Explosions
The risk of explosions around flaring operations is ever-present due to the volatility of the gases involved. An explosion can result in:
- Blunt Force Trauma: Workers can be struck by flying debris or thrown by the blast wave from an explosion, resulting in broken bones, internal injuries, or traumatic brain injuries.
- Hearing Loss: The loud noise associated with flaring and explosions can cause temporary or permanent hearing loss. Workers who are not equipped with proper hearing protection are particularly vulnerable.
How Refineries Can Mitigate Flaring Hazards
Mitigating the hazards of flaring operations requires a combination of engineering controls, administrative procedures, and worker training.
- Flare Gas Recovery Systems: Installing flare gas recovery systems can reduce the need for continuous flaring by capturing and recycling excess gases instead of burning them.
- Regular Maintenance and Inspections: Ensuring that all equipment related to flaring, including flare stacks and pipelines, is properly maintained and inspected can reduce the likelihood of malfunctions and accidents.
- Worker Safety Training: Comprehensive safety training programs that educate workers about the risks of flaring, proper personal protective equipment (PPE) usage, and emergency procedures are crucial for reducing injury rates.
- Air Monitoring Systems: Installing air monitoring systems around flare stacks can help detect toxic gas leaks and alert workers before harmful exposure occurs.
Flaring is a necessary part of oil refinery operations, but it comes with significant risks to workers and the environment. By implementing effective safety measures, refineries can minimize these risks and protect both workers and surrounding communities.
