Hilda Sibrian - Houston's Injury Attorney

Your Attorney for Chemical Exposure Injuries

Attorney Hilda Sibrian

How Common are Chemical Exposure Incidents in Houston?

Houston is one of the most important petrochemical producers in the United States, but with that title comes an unfortunate risk of dangerous chemical spills, hazardous gas releases, and other major exposure incidents caused by corporate negligence. These incidents happen all too often and at an alarming rate (at least once a month!). A sudden chemical exposure can happen fast and the effects can be immediate or prolonged. It can be frightening and potentially life threatening.

A gas release, a spill at work, or an unexpected blast of fumes can send you to the hospital with burns, breathing problems, or worse. These aren’t just slow-building conditions over years of exposure. These are the acute, short term incidents that hit hard and leave real lasting injuries.

When a company fails to follow safety rules, people get hurt. Workers. Families. Neighbors. And the consequences fall on you instead of the ones who caused the danger.

You deserve better.

    How Does Toxic Chemical Exposure Happen?

    Most people never expect a normal shift at a refinery, petrochemical plant, warehouse, or industrial jobsite to turn into a life changing emergency. But in Houston and across the Gulf Coast, chemical exposure injuries happen when safety gets skipped, equipment fails, or companies cut corners. Toxic exposure commonly happens during incidents like:

    • Pressurized releases and gas leaks from valves, lines, tanks, compressors, and railcar or truck connections, including ammonia, chlorine, hydrogen sulfide (H2S), benzene, sulfur dioxide, and other hazardous vapors.
    • Spills, splashes, and direct contact when chemicals are mishandled during loading, unloading, mixing, cleaning, or maintenance, especially when PPE is missing, wrong, or not enforced.
    • Unsafe storage and containment failures, like damaged drums, corroded tanks, leaking piping, improper labeling, or incompatible chemicals stored together.
    • Fires, explosions, and “secondary exposure” events, where smoke and airborne toxins spread fast through a facility, into nearby areas, or across a neighborhood.
    • Hazardous waste exposure from improper disposal, poor ventilation, or contaminated surfaces that keep harming workers long after the initial incident.
    • Transportation and public exposure incidents, including chemical spills from delivery trucks, tankers, or railcars, and releases near roads, schools, or homes.
    • Chemical Cleaner Exposure can also occur in unexpected settings like waterparks, swimming pools, hot tubs, or other facilities.

    Chemical exposure is never truly a case of “bad luck.” In the majority of cases, it traces back to preventable failures like ignored maintenance, missing safety procedures, inadequate training, or rushing production.

    Companies know the risks, but they choose to put profits over people.

    If you were exposed to toxic chemicals and got sick or injured, our team can investigate what happened, preserve evidence, identify who is responsible, and fight for the compensation you need for medical care, lost income, and long term effects.

    What are the Signs of Chemical Exposure?

    Many workers in Houston, especially in refineries, chemical plants, factories, and industrial centers, are exposed to toxic substances every day. But when something goes wrong—a gas leak, a fire, a safety failure—the consequences can be severe.

    We understand what you’re going through:

    Immediate symptoms:

    • Dizziness, vomiting, fainting
    • Persistent cough, trouble breathing
    • Skin, eye, or throat irritation
    • Visible burns or a burning sensation

    Long-term consequences:

    • Irreversible lung damage
    • Nervous system disorders
    • Cancer or chronic illnesses
    • Death from prolonged exposure

    These injuries don’t just affect your body, they put your job, your family stability, and your future at risk. And while you suffer, the insurance companies look for excuses to pay you as little as possible.

    We won’t let that happen. We fight to get full compensation for your medical care, lost wages, and everything you’ve lost because of someone else’s negligence.

    What Caused Your Chemical Exposure Injury?

    For over two decades, we’ve represented workers exposed to dangerous chemicals in factories, refineries, processing plants, and industrial sites, where a single error or omission changed lives forever.


    And in every case, there was something that could have been prevented:

    Insufficient Training

    Poor Maintenance

    Ignored Hazards

    Improper Chemical Handling

    Poor Supervision

    OSHA Violations

    Excessive Work Pressure

    Inadequate Protective Equipment

    Poor Internal Communication

    No Safety Protocols

    These are not minor oversights. They are negligent and dangerous decisions made by supervisors or employers who put your life at risk.

    We prove that fault. We gather evidence, hold the responsible parties accountable, and demand the compensation you deserve.

    Every second counts. While you read this, the company is already preparing its defense.

    Don’t face this alone. Call us today.

    Why Do you Need an Experienced Chemical Exposure Attorney?

    Cases like these are never simple. They often involve:

    • Employer negligence for ignoring safety protocols
    • Hazardous work conditions that go unreported
    • Leaks of substances like hydrogen sulfide, ammonia, chlorine, benzene, or other chemical compounds
    • Chronic health issues that develop over time

    With a lawyer who doesn’t know how to handle these cases, you could end up with minimal compensation—or none at all.
