Oilfield Injury

Toxic Chemical Exposure

Chemical exposure is one of the most dangerous — and most invisible — hazards in the Texas oilfield. Workers are exposed daily to hydrogen sulfide (H2S), benzene, volatile organic compounds (VOCs), drilling muds, completion fluids, produced water with naturally occurring radioactive materials (NORM), silica dust, and dozens of other toxic substances. The effects may not be immediate. Some conditions, like occupational cancers, silicosis, or neurological damage, develop over years or decades — and by the time a worker realizes the exposure is making them seriously ill, they may believe it is too late to pursue a claim. It is often not too late.

The Garza Law Firm has served Texas workers for over 50 years. Toxic exposure cases require a different kind of investigation than traumatic injury cases — they involve scientific causation evidence, industrial hygiene experts, detailed medical histories, and a careful analysis of the statute of limitations, which can be extended in exposure cases when the injured person could not reasonably have known the cause of their illness. We have handled these cases, and we take them seriously.

If you worked in the oilfield and now face a health condition you believe may be connected to chemical exposure — whether from a single incident or years of ongoing exposure — call us. We serve workers throughout Texas from our offices in San Antonio and Midland.

Key Facts About Toxic Chemical Exposure in Texas

Benzene, a known human carcinogen present in crude oil and refined products, is linked to leukemia and other blood cancers. OSHA sets a permissible exposure limit (PEL) of 1 part per million (ppm) for an 8-hour workday, but oilfield workers are frequently exposed at levels that exceed this limit without adequate monitoring or respiratory protection.

Hydrogen sulfide (H2S) is one of the most acutely toxic gases encountered in oilfield work. At low concentrations it causes headaches, nausea, and disorientation; at high concentrations it can cause instantaneous loss of consciousness and death. The Texas Railroad Commission requires H2S safety plans for wells with potential H2S production, and failures in these plans can establish employer liability.

NORM — naturally occurring radioactive material — is found in scale and sludge buildup in production equipment, pipelines, and storage tanks across Texas oilfields. Workers who regularly handle or clean NORM-contaminated equipment may face elevated cancer risks, and employer obligations to monitor and manage this exposure are defined by Texas regulations.

Occupational silica exposure leading to silicosis is an irreversible and often fatal lung disease. OSHA's updated silica standard, effective in 2018 for oil and gas operations, cut the PEL in half and added requirements for medical surveillance — violations of which can be used as evidence of negligence in a lawsuit.

Texas courts apply the 'discovery rule' in many latent occupational disease cases, meaning the two-year statute of limitations may not begin to run until the worker knew or should have known that their illness was linked to their workplace exposure. This critical exception makes it worth consulting an attorney even if you believe too much time has passed.

Common Questions About Toxic Chemical Exposure

I was exposed to chemicals years ago and was just diagnosed with a serious illness. Can I still file a claim?

Possibly yes. Texas applies the discovery rule to latent disease cases — the statute of limitations clock may not start until you knew or reasonably should have known that your illness was caused by occupational exposure. An attorney can evaluate when your limitations period began based on when you received your diagnosis and when the causal connection to your work became apparent. Do not assume you are time-barred without consulting us.

My employer says my illness is not related to my job. How do I prove otherwise?

Causation is the central challenge in toxic exposure cases, and it requires scientific evidence — industrial hygiene monitoring data, your work history, toxicological analysis, and expert medical testimony linking your specific exposure to your specific condition. The Garza Law Firm retains occupational medicine physicians, industrial hygienists, and toxicologists who specialize in exactly this type of analysis.

Can I sue the company that manufactured the chemicals that made me sick?

Yes, if the chemical manufacturer failed to provide adequate warnings about health risks or designed the product in an unreasonably dangerous way. Texas product liability law allows claims against manufacturers and distributors, and in occupational disease cases, chemical companies are frequently defendants alongside the employer and the oil operator. Their safety data sheets (SDS) and internal toxicology records often become key evidence.

I was exposed in a one-time accident — a chemical release or spill — not long-term exposure. Does that change my case?

Acute exposure incidents are often stronger cases than chronic exposure cases because causation is more direct and the incident is better documented. If you were injured in a chemical spill, gas release, or tank vapor incident, you have a standard two-year personal injury statute of limitations and should act quickly to preserve evidence and identify all responsible parties.

You Don't Have to Figure This Out Alone

When you hire The Garza Law Firm, we guide you through every step of the legal process so you can focus on what matters most — your recovery.

2

Exposure History Development

We work with you and, where available, former co-workers to build a detailed occupational exposure history — documenting which chemicals, in what quantities, under what conditions, and for how long you were exposed at each job site.

3

Expert Team Assembly

We retain industrial hygienists to reconstruct your exposure levels, occupational medicine physicians to establish medical causation, and toxicologists to explain to a jury exactly how the chemical caused your specific diagnosis.

4

Regulatory and Employer Records Review

We subpoena OSHA inspection records, your employer's air monitoring data, safety data sheets provided by chemical manufacturers, and any internal exposure monitoring records that should have been maintained under federal and Texas law.

5

Multi-Party Liability Mapping

We identify claims against your employer (direct negligence or non-subscriber lawsuit), the oil operator, chemical manufacturers, and any third-party equipment suppliers whose products contributed to your exposure, maximizing the pool of compensation available to you.
