Workers at industrial plants, refineries, and chemical facilities across Texas face daily exposure to toxic chemicals that can cause devastating acute injuries and chronic diseases. From hydrogen sulfide inhalation that kills within minutes to long-term benzene exposure that causes leukemia years later, toxic chemical exposures represent one of the most serious occupational health hazards in the state. These exposures are not inevitable consequences of industrial work — they result from inadequate ventilation, failed containment systems, insufficient personal protective equipment, poor monitoring, and management decisions that prioritize production over worker health. McFarlane Law represents Texas workers and community members who have been harmed by toxic chemical exposures at industrial facilities.

Common Toxic Exposures at Texas Industrial Facilities

Texas industrial facilities expose workers to hundreds of toxic substances. Benzene, a known human carcinogen found extensively in petroleum refining and chemical manufacturing, causes leukemia, lymphoma, and other blood cancers with chronic exposure. Hydrogen sulfide (H2S), prevalent in oil and gas operations and petroleum refining, is immediately dangerous to life at concentrations above 100 parts per million and has killed numerous Texas workers. Asbestos, still present in older refineries and industrial facilities as insulation, gasket material, and fireproofing, causes mesothelioma, lung cancer, and asbestosis. Silica dust from sandblasting, abrasive operations, and construction activities at industrial sites causes silicosis, a progressive and irreversible lung disease. Hydrofluoric acid, used in petroleum refining alkylation units, penetrates skin on contact and causes systemic fluoride poisoning that can be fatal. Chlorine, ammonia, and phosgene releases from chemical plant incidents can cause severe respiratory injury and death. Heavy metals including lead, mercury, cadmium, and chromium are present at various industrial operations and cause neurological damage, kidney disease, and cancer with chronic exposure.

Acute vs. Chronic Toxic Exposure Injuries

Toxic chemical exposures cause two distinct categories of injury. Acute exposures — sudden, high-concentration contact with toxic substances — cause immediate, dramatic injuries. Chemical burns from acids and caustics destroy skin and underlying tissue on contact. Inhalation of toxic gases and vapors causes pulmonary edema, chemical pneumonitis, reactive airways disease, and respiratory failure. Eye exposure to chemicals causes corneal burns and permanent vision loss. Systemic toxicity from absorbed chemicals can cause organ failure, cardiac arrest, and death. Chronic exposures — lower-concentration contact over weeks, months, or years — cause insidious diseases that may not manifest for decades. Occupational cancers (leukemia, mesothelioma, bladder cancer, liver cancer) typically appear 10–40 years after the exposure that caused them. Chronic respiratory diseases (occupational asthma, COPD, pulmonary fibrosis) develop progressively over years of repeated exposure. Neurological damage from solvents and heavy metals causes cognitive impairment, peripheral neuropathy, and tremors. Reproductive effects including infertility, birth defects, and miscarriage can result from exposure to certain industrial chemicals.

Employer Obligations and Common Failures

OSHA sets permissible exposure limits (PELs) for hundreds of toxic substances and requires employers to monitor workplace air quality, implement engineering controls (ventilation, containment, substitution), provide appropriate personal protective equipment (PPE), train workers on chemical hazards, and maintain Safety Data Sheets (SDS) for all hazardous chemicals on site. The Hazard Communication Standard (HazCom) requires employers to inform workers about the chemical hazards they face. Despite these requirements, toxic exposures continue because many employers fail to maintain adequate ventilation systems, ignore air monitoring results showing excessive exposure levels, provide inadequate or poorly maintained PPE, fail to train workers on the specific chemicals they handle, and push workers to continue operations during upsets or maintenance activities when exposure levels are elevated. Some employers actively discourage workers from reporting exposure symptoms, fearing regulatory scrutiny and liability. These failures are not merely regulatory violations — they represent deliberate choices to expose workers to known hazards for the sake of production efficiency.

Building a Toxic Exposure Claim with McFarlane Law

Toxic exposure cases present unique legal challenges, particularly for chronic exposure claims where the connection between workplace exposure and disease must be established over a timeline spanning years or decades. McFarlane Law works with industrial hygienists who can reconstruct historical exposure levels using facility records, air monitoring data, process information, and industry-standard exposure modeling. We retain toxicologists who establish the causal relationship between specific chemical exposures and our client’s medical condition. For occupational cancer claims, we work with oncologists and epidemiologists who can testify about exposure-disease relationships based on the scientific and medical literature. We obtain the employer’s chemical inventory, air monitoring records, PPE program documentation, and training records to demonstrate failures in exposure control. For acute exposure cases, we secure incident reports, atmospheric monitoring data, emergency response records, and medical documentation from the immediate aftermath. McFarlane Law pursues both workers’ compensation and third-party liability claims to maximize recovery. Contact us at (512) 222-4900 or (432) 803-5000.
