What Happened
On the evening of March 23, 2026, an explosion and large fire erupted at the Valero oil refinery in Port Arthur, Texas — one of the largest refineries in the United States processing approximately 435,000 barrels of oil per day. The blast, believed to have originated in a diesel hydrotreater unit, sent massive plumes of thick black smoke billowing into the sky and prompted immediate emergency response from local, state, and federal agencies.
Jefferson County officials ordered residents on the west side of Port Arthur to shelter in place for over 12 hours. The Texas Commission on Environmental Quality and the EPA deployed air monitoring teams to the scene. Residents reported hearing a loud explosion and feeling their homes shake miles away from the refinery.
While officials reported no immediate injuries and stated air quality was within safe thresholds at monitoring points — health effects from chemical exposure are not always immediate. Symptoms from exposure to refinery emissions, hydrogen sulfide, and other toxic byproducts can appear hours, days, or even weeks after the incident.
Do You Qualify?

You were ordered to shelter in place on March 23-24, 2026
You smelled chemical odors or saw smoke from the explosion
You experienced headaches, nausea, breathing difficulty, or eye irritation

Your children were affected — schools were closed or delayed
You suffered property damage or business losses due to road closures
Symptoms To Watch For After Chemical Exposure

What You Should Do Right Now
1
Seek Medical Attention
Even if you feel fine right now — see a doctor and document any symptoms. Chemical exposure effects can be delayed. Medical records are your most important evidence.
2
Document Everything
Take photos, save news articles, write down what you experienced, when you first smelled smoke or chemicals, and any symptoms you or your family have had.
3
Do NOT Give Statements
Do not give recorded statements to Valero representatives or insurance adjusters. They work for the company — not for you. Speak with an attorney first.

Common Questions
I wasn't injured — can I still have a claim?
+
Possibly yes. Being forced to shelter in place, experiencing fear, anxiety, disruption to your daily life, or property damage may all form the basis of a legal claim even without physical injury. An independent attorney can evaluate your specific situation for free.
Officials said air quality was safe — does that mean I have no claim?
+
Not necessarily. Official air monitoring only measures certain pollutants at certain locations and times. Exposure close to the source or before monitoring began may have been significantly higher. Additionally, health effects from some chemical exposures can manifest days or weeks later. An attorney and medical expert can evaluate your specific exposure.
How much could my claim be worth?
+
It depends on the severity of your exposure, health effects, property damage, and other factors. Industrial explosion cases in Texas have resulted in significant settlements, particularly when large corporations like Valero are involved. A free consultation with an attorney is the best way to understand your specific claim's value.
How much does it cost to hire an attorney?
+
Nothing upfront. Attorneys in our network work on contingency — meaning they only get paid if they win your case. You pay zero out of pocket regardless of the outcome.
I'm a Valero employee — can I still file a claim?
+
If you are a direct Valero employee, Texas workers' compensation laws may affect your options. However, if you are a contractor or work for a company that contracts with Valero, you may have additional legal options. Speak with an attorney to understand your rights.
