The Dangers of Oil and Gas Refining

The Wynnewood Refinery is a small oil and gasoline refinery located in south-central Oklahoma. Despite being a relatively small refinery compared to some of the massive refineries in the Gulf Coast states, workers in Wynnewood face many of the same hazards.

Oil and gas refining, like any industrial process, has certain dangers and associated risks. Here are some potential dangers:

Fire and Explosions

Gasoline is highly flammable and volatile. During the refining process, there is a risk of fires and explosions if proper safety measures are not in place. Accidental ignition of gasoline vapors can lead to catastrophic incidents.

Health risks to Workers

Refinery workers may face occupational hazards such as exposure to toxic fumes, chemical burns, physical injuries, and noise pollution. Prolonged exposure to certain chemicals or unsafe working conditions can lead to chronic health problems, including respiratory issues, skin disorders, or increased risk of certain cancers.

Chemical Hazards

Refining involves the use of various chemicals and solvents, including corrosive acids, caustic substances, and toxic compounds. Exposure to these chemicals can result in burns, skin irritation, respiratory problems, or long-term health effects if safety precautions are not followed.

Environmental Pollution

Refineries can release pollutants into the environment. If not properly controlled, emissions from refining processes can contribute to air pollution, including the release of greenhouse gases, volatile organic compounds (VOCs), and hazardous air pollutants (HAPs). Accidental spills or leaks of gasoline or other petroleum products can also lead to soil and water contamination, harming ecosystems and wildlife.

Transportation Risks

Transporting large quantities of gasoline and other petroleum products via pipelines, tankers, or trucks involves its own set of risks. Accidents during transportation, such as spills, leaks, or collisions, can result in fires, explosions, and environmental damage, as well as pose risks to human life and property.

Process Upsets and Equipment Failures

Refinery operations are complex, involving numerous mechanical systems and equipment. Equipment failures, process upsets, or human errors can lead to unplanned shutdowns, release of hazardous substances, or other accidents that jeopardize safety and disrupt operations.

 What are Some Common Causes of Refinery Explosions?

There are many causes of oil and gas refinery explosions. Some causes seem to be more common than others, however, such as human error or poor safety features. At Kherkher Garcia, we have noted the following causes to be among the most common:

  • Human Error: This is the most common cause of refinery explosions, and can include things like:
    • Careless cigarette smoking
    • Improper maintenance of equipment
    • Shortcuts in safety procedures
    • Inadequate training of workers
  • Defective Equipment: Equipment malfunctions can be caused by defects or negligence, and can lead to explosions if flammable materials are present.
  • ‘Dirty’ Chemicals: Refineries use volatile chemicals to purify extracted oil. These chemicals must be properly stored and handled. They can be very dangerous if they come into contact with heat, sparks, or other ignition sources.
  • Well Blowouts: An oil well blowout refers to the uncontrolled release of crude oil from an oil well. This can happen when the pressure inside the well becomes too great, and can lead to explosions if there are flammable materials present.
  • Unseen Corrosion: Corrosion can weaken equipment over time, making it more likely to malfunction and cause an explosion.
  • Poor Safety Procedures: Refineries must have strict safety procedures in place to prevent explosions. If these procedures are not followed, it can increase the risk of an explosion.

It is important to note that these are just some of the most common causes of oil and gas refinery explosions. There are many other factors that can contribute to an explosion, and it is often difficult to determine the exact cause. Investigations to find the cause of an explosion often take months or sometimes years to complete.

Types of Injuries Caused by Refinery Explosions

Explosions can cause a wide range of injuries, depending on the nature and intensity of the explosion, as well as the proximity of individuals to the blast. Here are some common injuries caused by explosions:

Blast Injuries

The primary cause of injuries in an explosion is the blast wave. It is a wave of high-pressure air that spreads rapidly from the site of the explosion. Blast injuries can result from the direct impact of the blast wave on the body or through indirect mechanisms such as being thrown against objects or collapsing structures. Blast injuries can include:

  • Primary Blast Injuries: These are caused by the direct effect of the blast wave on the body. They primarily affect gas-filled organs, such as the lungs, intestines, and ears. Injuries can include lung damage, gastrointestinal injuries, ruptured eardrums, or damage to other organs.
  • Secondary Blast Injuries: Occur when individuals are struck by flying debris, fragments, or objects propelled by the blast. They can cause lacerations, puncture wounds, fractures, or traumatic amputations.
  • Tertiary Blast Injuries: These occur when individuals are thrown or propelled by the force of the blast, impacting other objects or surfaces. This can result in blunt trauma injuries, fractures, head injuries, or spinal injuries.
  • Quaternary Blast Injuries: Encompass a range of other injuries that may occur indirectly due to the explosion, such as burns, crush injuries, inhalation of toxic gases or smoke, or psychological trauma.

Thermal Injuries

Explosions generate intense heat and flames, leading to thermal injuries. These injuries can result in burns of varying degrees, including first-degree, second-degree, or third-degree burns. Burns can affect the skin, underlying tissues, and respiratory system if hot gases or smoke are inhaled.

Shrapnel Injuries

Shrapnel refers to fragments or pieces of objects that are propelled by the explosion. Injuries due to shrapnel can include penetrating wounds, deep lacerations, fractures, and internal organ damage.

Traumatic Brain Injuries (TBIs)

Explosions can cause TBIs due to the forceful impact on the head or when individuals are thrown against hard surfaces. TBIs can range from mild concussions to severe brain injuries, potentially leading to long-term cognitive, physical, or psychological impairments.

Hearing and Vision Loss

The intense pressure generated by explosions can cause severe damage to the ears, resulting in hearing loss or permanent deafness. Additionally, the bright flash of light during explosions can cause temporary or permanent vision loss or eye injuries.

Psychological Trauma

Experiencing or witnessing an explosion can lead to psychological trauma, including post-traumatic stress disorder (PTSD), anxiety, depression, or other mental health conditions.

The severity and type of injuries that occur during an explosion can vary depending on factors such as proximity, protective barriers, and individual circumstances. Prompt medical attention and appropriate trauma care are crucial for treating blast injuries and minimizing long-term complications.

Types of Injuries Caused by Fires

Explosions often result in fires, and both events can be catastrophic. Injuries due to a fire can vary from those caused by an explosion. There are many different types of fire injuries, but some of the most common include:

  • Burns: Burns are the most common type of fire injury, and can range in severity from minor to life-threatening. These injuries can be caused by direct contact with flames, hot objects, or hot gases.
  • Smoke Inhalation: Smoke inhalation is another common type of fire injury. Inhaling smoke can cause respiratory problems, including coughing, wheezing, and difficulty breathing. In severe cases, smoke inhalation can lead to death.
  • Injuries from Falling Debris: Fires can cause debris to fall, which can injure people who are nearby. Debris can include bricks, concrete, glass, and other objects.
  • Hearing Loss: Fires can cause hearing loss, either from the noise of the fire itself or from the sound of explosions.
  • Psychological Trauma: Fires can cause psychological trauma, including post-traumatic stress disorder (PTSD). PTSD can cause symptoms such as flashbacks, nightmares, and anxiety.
