Blume v. Port Authority Trans-Hudson Corporation

Background

Thomas Blume and Jason Martinez brought claims under the Federal Employers’ Liability Act, a federal law governing railroad employers’ liability for injuries caused in whole or in part by employer negligence. They alleged that PATH’s use of Tank Brite Plus, an industrial cleaning chemical, exposed them to harmful fumes and liquid between January and May 2016.

The plaintiffs alleged that PATH failed to train employees in the chemical’s safe use, provide appropriate personal protective equipment, give adequate warnings, maintain adequate safety rules, and provide sufficient ventilation. The safety data sheet for Tank Brite Plus described hazards including skin corrosion, eye damage, aspiration injuries, respiratory or skin sensitization, and possible harm or death if inhaled. It recommended good general ventilation, air-purifying respirators, chemical goggles, and chemical-resistant gloves.

Blume worked at PATH’s Harrison Car Maintenance Shops but did not use Tank Brite Plus himself. He testified that he could smell the chemical from his workstation, that it dripped onto his shoulders and skin, and that he developed symptoms including a sore throat, coughing, bloody noses, and chest tightness. Medical providers treated him for chest, breathing, nose, sinus, and throat problems.

Martinez used Tank Brite Plus to clean train cars several days a week for several months. He sometimes used the chemical diluted and sometimes undiluted. He testified that the workspace had broken fans and obstructed ventilation, that the chemical contacted his skin and eyes, and that PATH did not provide him with a respirator until May 25, 2016. He reported headaches, runny noses, coughing, bloody noses, sore throat, chest tightness, and asthma attacks. A doctor diagnosed him with occupational asthma, reduced ventilatory capacity, reactive airways dysfunction syndrome, lung nodules, chest tightness, and difficulty breathing.

Summary-judgment motion

PATH moved for summary judgment, which asks the court to enter judgment without a trial when the record shows no genuine dispute over a material fact and the moving party is entitled to judgment as a matter of law. PATH argued that the plaintiffs could not prove causation without admissible, methodologically reliable expert testimony and that Dr. Donald A. Fox’s report did not satisfy that requirement.

Dr. Fox, a toxicologist and neurobiologist, concluded that exposure to Tank Brite Plus caused the plaintiffs’ acute respiratory injuries and continuing respiratory and pulmonary symptoms. He analyzed the route, duration, concentration, and mechanism of exposure. Because he did not find studies directly addressing Tank Brite Plus’s effects on humans, he relied on studies concerning its four component chemicals. He also relied on the plaintiffs’ accounts regarding the nature and duration of their exposure. PATH challenged those methods and argued that Dr. Fox lacked sufficient information about the chemical’s concentration and dosage.

Legal standard under the Federal Employers’ Liability Act

The court explained that a plaintiff bringing a negligence claim under the Federal Employers’ Liability Act must prove duty, breach, foreseeability, and causation, but the causation burden is less demanding than under ordinary common-law negligence. The question is whether the evidence could reasonably support a finding that employer negligence played any part, even the slightest, in producing the injury.

The court rejected PATH’s premise that expert testimony was necessarily required. It relied on decisions stating that circumstantial evidence, expert testimony, or common knowledge may support an inference of causation in Federal Employers’ Liability Act cases. The court reasoned that a jury could understand the connection between inhaling a hazardous chemical and injuries to the throat, nostrils, and lungs, particularly where the alleged injuries involved observable respiratory symptoms rather than a complex condition such as cancer.

Causation and expert testimony

Even without considering Dr. Fox’s opinions, the court found evidence that Blume and Martinez worked near diluted and undiluted Tank Brite Plus without the protective equipment recommended by the manufacturer. There was also evidence that the facility was inadequately ventilated, that the plaintiffs developed respiratory and pulmonary symptoms after their exposure, and that the safety data sheet identified similar symptoms as possible effects of exposure.

The court further stated that some aspects of Dr. Fox’s testimony were admissible under Federal Rule of Evidence 702 and the Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals, Inc. The court found that his qualifications were undisputed and that he was qualified to explain how Tank Brite Plus could have toxic effects. PATH could challenge the bases for those opinions through cross-examination because such challenges generally affect the testimony’s weight rather than its admissibility. The court did not decide whether all of Dr. Fox’s other opinions were admissible.

Disposition

The court held that the record presented a genuine dispute about whether PATH’s failure to take proper precautions while using Tank Brite Plus played a part in causing the plaintiffs’ inhalation injuries. Judge Colleen McMahon denied PATH’s motion for summary judgment and ordered the clerk to close the motion at Docket Number 18. The opinion did not decide the plaintiffs’ ultimate entitlement to damages or otherwise enter judgment on the underlying claims.
