# Human Factors Expert Witness’ Opinions About Tripping on the Raised Fuel Pump Excluded

Posted on November 19, 2024 by Expert Witness Profiler

On November 30, 2022, Plaintiff, Cynthia Burgett, was at the Hy-Vee Fast & Fresh convenience store in Prairie Village, Kansas, to purchase gas. The gas station’s fuel pump islands are shaped like an “H” and also referred to by the parties as a “dog bone” shape. The fuel pump islands are elevated above the parking lot pavement. While at Defendant’s gas station, Plaintiff tripped over a fuel pump island and suffered serious injuries. Plaintiff’s alleged injuries are extensive and she asserts that she will need lifetime medical care as a result.

Plaintiff asserted a claim of negligence against Defendant. Plaintiff contended that the fuel pump island was an unreasonably dangerous tripping hazard, that Defendant had knowledge or should have known that it was dangerous, that the design was not in accordance with industry standards, and it lacked safety features of Defendant’s standard pump and the industry standards. Both parties will present expert testimony at trial. Plaintiff has identified two experts that will testify as to the dangerousness of the fuel pump island: [Lila Laux](https://expertwitnessprofiler.com/expert-witness/Lila-Laux/1521283), a human factors expert, and [Albert Kerelis](https://expertwitnessprofiler.com/expert-witness/Albert-Kerelis/1542219), a licensed architect. Defendant has identified Richard Serignese as a non-retained expert to testify about the design and maintenance of fuel pumps. The parties have filed motions to exclude the opinions of these experts.

## **Discussion by the Court**

### **Lila Laux**

Laux’s opinions include the following: Plaintiff behaved how most people would behave at a gas station; the fuel pump created a hazard because Plaintiff’s attention was not attracted to the “extended lobe in her path” and she was unlikely to see it; the extended lobe of the fuel pump created an unexpected trip hazard that caused Plaintiff to trip; it is unreasonable to expect that people walking between the store and the fuel pump would expect or detect the unmarked and undifferentiated pump pedestal protruding into their path; and it was foreseeable that customers could fail to detect the raised pedestal and trip as they walked to their vehicle.

#### **Qualifications**

Defendant made a cursory attempt to exclude Lila Laux’s testimony on the basis that she is not qualified.

 A review of Laux’s resume shows that she has decades of experience on human factors and her opinions largely relate to how individuals and Plaintiff would navigate the obstacle of the fuel pump and whether they would be aware of the elevated fuel pump in their path based on her experience. The Court finds that she is qualified to offer such opinions based on her education and experience.

#### **Helpfulness**

Defendant argued that Laux’s opinions would not assist the jury in understanding the evidence or facts in this case because what ordinary people see in situations and how they understand their surroundings are within the common understating of a juror. 

Here, the Court found that Laux’s opinions and testimony would not be helpful to the jury. Laux offers opinions regarding the types of customers that would go to a gas station, how customers would walk from the fuel pump to the convenience store, whether customers would expect to see or detect the raised fuel pump, and whether it was foreseeable that someone would trip on the raised fuel pump. Such opinions are not helpful here because the average juror has experience getting gas at a gas station. An average juror also has experience walking from a fuel pump to the convenience store to either pay for the gas or to go inside and purchase additional items.

#### **Albert Kerelis**

Kerelis is a licensed architect and will provide the following opinions at trial: 1) the edge of the fuel pump island was dangerous and caused Plaintiff to fall; 2) the edge of the fuel pump island was a low obstruction in a foreseeable pedestrian path that violated the standard of care for safe walkways; 3) the property owners should have known it was dangerous and provided warnings to pedestrians; 4) the failure to eliminate the hazardous condition or provide warnings was a violation of the standard of care for safe walkways and created the hazardous condition that caused Plaintiff’s injury; and 5) the owner violated nationally recognized standards of care and the city’s codes and ordinances.

#### **Qualifications**

Defendant asserted that Kerelis is not qualified to provide expert testimony on the fuel pump island because he has not prepared design drawings in the past five years, has not designed any projects in Kansas, and has not prepared a design with a fuel pump island in at least 15 years. Kerelis is a licensed architect with decades of experience who has designed hundreds of sites. He testified extensively regarding his experiences in site design and the related considerations of safety for pedestrians and users of sites when designing sites. The Court held that Defendant’s arguments called into question the weight of his testimony rather than his qualifications.

#### **Reliability**

Essentially, Defendant argued that the expert’s opinions are not reliable because he fails to cite any publications regarding the design and maintenance of fuel pump islands. Defendant took issue with Kerelis’ reliance on several national publications which he has identified as standards of care in the industry because they are not publications regarding the design and maintenance of fuel pump islands. Kerelis’ opinions, however, clearly stated that Defendant violated the standards of care regarding safe walkways and warnings regarding obstructions. His expert report cites to various publications, including a publication by ASTM International, formerly the American Society for Testing and Materials (ASTM), which is a “globally recognized leader in the development and delivery of professional consensus standards.”

In the report, Kerelis states that ASTM’s publication, “Standard Practice for Safe Walking Surfaces, is a nationally recognized standard of care for the safe construction and maintenance of walkways to prevent pedestrian falls.” That publication states that “in situations where a short flight stair or single step transition exists or cannot be avoided, obvious visual cues shall be provided to facilitate step identification.”

The Court held that Defendant’s arguments claiming Kerelis failed to cite publications on fuel pump islands are unpersuasive. The standards cited by Kerelis relate to obstructions in a walkway and based on the facts in this case and the expert opinions, a jury could conclude that the fuel pump island extended into the walkway. 

#### **Richard Serignese**

Defendant identified Richard Serignese as a non-retained expert that will “testify that the shape, size, color, and condition of the fuel pump island is within industry standards and that Hy-Vee did not violate any standard of care in regard to the maintenance of the fuel pump islands.”

Serignese is the Vice Presicent and General Manager of Simon Surfaces and will testify based on his “knowledge, education, training, and experience in the fuel island industry.” 

With respect to his opinions, Serignese testified that he actually doesn’t “know the exact industry standard” for fuel pump island designs and that his “understanding has always been people pick what they want to pick. It’s a matter of preference. I don’t know that — I don’t know what the — anybody could tell you what the exact industry standard is.” He then reiterated that he did not know the industry standard for fuel islands and admitted that he could not say that this particular design is or is not industry standard.

Defendant argued that Serignese’s inability to articulate an industry standard should not preclude him from testifying because his testimony is that he doesn’t think there is an industry standard. Defendant, however, offered Serignese as an expert who will testify as to the industry standard and that Defendant’s fuel pump island is within that standard. The Court held that Serignese is not qualified to opine as to these issues and his deposition makes clear that he has no opinion on these issues.

Defendant designated Serignese as an expert who will testify that Defendant met the standard of care for maintaining the fuel pump island. The Court held that his deposition testimony, however, made it clear that he has no expertise in that area.

## **Held**

1. The Court granted the Defendant’s motion to exclude the testimony of Lila Laux.

2. The Court denied the Defendant’s motion to exclude the testimony of Albert Kerelis.

3. The Court granted the Plaintiff’s motion to exclude the testimony of Richard Serignese.

## **Key Takeaways:**

- Laux offers opinions regarding the types of customers that would go to a gas station, how customers would walk from the fuel pump to the convenience store, whether customers would expect to see or detect the raised fuel pump, and whether it was foreseeable that someone would trip on the raised fuel pump. Such opinions are not helpful here because the average juror has experience getting gas at a gas station.

- Kerelis’ opinions, however, clearly stated that Defendant violated the standards of care regarding safe walkways and warnings regarding obstructions. His expert report cites to various publications, including a publication by ASTM International, formerly the American Society for Testing and Materials (ASTM), which is a “globally recognized leader in the development and delivery of professional consensus standards.” The Court held that Defendant’s arguments claiming Kerelis failed to cite publications on fuel pump islands are unpersuasive.
