El Segundo residents know our city's skyline well. The tall structures of petroleum refineries have been part of our community for over a century. Living near these industrial facilities means understanding the risks they bring, especially when it comes to the air we breathe. When accidents happen at these facilities, the effects reach far beyond the refinery gates. They impact neighborhoods from Manhattan Beach to Hawthorne and beyond.

At Bloom Injury Law, we've worked with South Bay residents who lived through industrial accidents. Understanding how an oil refinery explosion affect air quality helps our community stay safe and make smart decisions during these events.
An oil refinery explosion dramatically worsens air quality by releasing large amounts of hazardous chemicals into the atmosphere all at once. These explosions send substances like benzene, sulfur dioxide, hydrogen sulfide, and particulate matter into the air that nearby communities breathe. Unlike controlled emissions from normal refinery operations, explosions release these pollutants rapidly and unpredictably. The force of the blast propels chemicals high into the air where wind carries them across surrounding neighborhoods, sometimes traveling miles from the original site.
The impact on air quality can last from hours to several days, depending on the size of the explosion, weather conditions, and which chemicals were released. Visible black smoke contains toxic particles and incompletely burned chemicals that settle over downwind areas. Weather patterns like temperature inversions can trap pollutants close to the ground, keeping them in breathing zones longer. People exposed to this polluted air may experience coughing, breathing difficulties, eye irritation, headaches, and other health problems. Some chemicals also settle on surfaces in the community, creating longer-term exposure risks even after the visible smoke clears.
When an explosion occurs at a petroleum facility, dangerous chemicals immediately release into the air. These facilities turn crude oil into different products like gasoline and diesel. Each part of the refinery contains different chemicals. An explosion can release all of these substances at once into the air that people in Playa del Rey, Torrance, and other nearby areas breathe.

The blast from an explosion sends chemicals high into the sky very quickly. Unlike normal emissions from daily operations, explosion releases happen fast and without warning. Common substances released include:
The force of the explosion pushes these chemicals into the atmosphere. Wind patterns then carry them across South Bay communities. They can reach as far as Inglewood or down to the Palos Verdes Peninsula.
Several factors determine how an oil refinery explosion affect air quality in different areas:
The hills of Palos Verdes to the south and the rise toward Baldwin Hills create wind patterns that can move pollutants in unexpected ways.
The immediate impact on air quality depends on the size of the explosion, which chemicals were involved, and the weather. Air quality monitoring stations throughout the region measure pollution levels and detect when they spike.
Following an explosion, pollution levels jump dramatically. Monitoring stations detect:
The black smoke plumes you can see from LAX or nearby beaches contain incompletely burned chemicals and carbon particles. This smoke is dangerous because it carries both particles and toxic substances.
How long the air stays polluted varies. Initial problems may last several hours while firefighters work to stop the release. However, air quality can stay bad for days because:
Temperature inversions, which are common in the South Bay, make things worse. Warm air sits on top of cool air and acts like a lid. This traps pollutants close to the ground instead of letting them rise and spread out. When this happens, residents from Redondo Beach to LAX may notice bad air quality for longer periods.
Understanding how an oil refinery explosion affect air quality over time is important. Some chemicals stay in the environment long after the smoke clears. They settle onto:
Benzene, a cancer-causing chemical found in petroleum, can remain in the environment for a long time. When it lands on surfaces at the El Segundo Dog Park or school playgrounds, people can be exposed weeks after the explosion.
When air quality gets bad after a refinery incident, people experience various health problems. Knowing the symptoms helps you protect yourself and your family.
Short-term health effects include:
These symptoms can appear within hours of exposure. The smell alone can linger in areas like Chevron Park or along Rosecrans Avenue long after the incident.
Certain groups need to be extra careful when air quality drops:
If you fall into any of these groups, take extra precautions during air quality alerts.
Multiple government agencies watch over refineries and respond when accidents happen. They work to keep residents safe and informed.
Different organizations have specific jobs during and after refinery incidents:
After an explosion, these agencies set up mobile monitoring equipment in neighborhoods, schools, and parks. They measure pollution levels and track how air quality changes. This information helps them decide whether to tell people to stay inside or evacuate.
During refinery incidents, residents receive safety information through:
Community members along Vista del Mar or around Manhattan Beach often share information on social media too. Sign up for your city's emergency notification system if you haven't already.
When officials warn about poor air quality after an explosion, take action right away to reduce your exposure.
The best way to protect yourself:
