I. INTRODUCTION

Patricia Cesena sued Southern California Edison Company (Edison) for injuries she sustained when she fell on a ramp while working at Edison’s San Onofre Nuclear Generation Station (SONGS). Cesena moved in limine to exclude on relevance grounds evidence showing there had never been an accident on that ramp in its 18-plus-year history. The trial court granted the motion in part, allowing this “safety history evidence” for the limited purpose of proving whether Edison had notice of a dangerous condition on its property, but not for proving the underlying question of whether the ramp constituted a dangerous condition in the first place. The court gave a special jury instruction implementing this ruling. Following a nearly three-week trial, the jury found in Cesena’s favor and awarded her over $3.3 million. On appeal, Edison contends the trial court committed prejudicial instructional error by instructing the jury about the limited purpose for which it could consider the safety history evidence. Although we disagree with Edison’s characterization of its challenge as being aimed at the special limiting instruction — we view it as being aimed at the underlying evidentiary ruling admitting the evidence for a limited purpose — we agree the trial court erred in excluding the safety history evidence as irrelevant to the issue of whether the ramp constituted a dangerous condition. Under established California law, safety history evidence is relevant to the question of whether a dangerous condition exists because the evidence has a “tendency

in reason to prove” that condition. (Evid. Code,1 § 210; see Beauchamp v. Los Gatos Golf Course (1969) 273 Cal.App.2d 20, 37 (Beauchamp); Lupash v. City of Seal Beach (1999) 75 Cal.App.4th 1428, 1435 (Lupash).) Therefore, the trial court’s categorical exclusion of the safety history evidence for this

2 purpose was error. Based on our review of the entire record, however, we further conclude the error did not prejudice Edison. Accordingly, the judgment is affirmed.

II. FACTUAL AND PROCEDURAL BACKGROUND

A. SONGS

SONGS began operating in the early 1980s. In 2013, Edison ceased power generation operations at SONGS and began decommissioning (i.e., safely shutting down) the plant. Cesena’s accident occurred in the SONGS Unit 3 spent fuel room, where radioactive fuel removed from the reactors was stored while it cooled in a swimming pool-like facility. In the room, a “machine . . . kind of like a rail car” operated on train-like rails to move spent fuel around the pool. Sometime in the 1990s, Edison installed an elevated walkway over these rails to eliminate them as a tripping hazard. A ramp at each end of the elevated walkway sloped down to ground level. The ramp at issue here was six feet wide and descended about eight inches in height over a length of about 26 inches, resulting in a 35-percent grade sloping downwards toward the spent fuel room’s exit door. “Diamond plate” metal with approximately four-inch- wide lateral strips of nonslip tape spaced about every four inches covered the ramp surface. Between the bottom of this ramp and the exit door was a 37- inch-long landing. The exit door from the spent fuel room to other parts of the Unit 3 facility swung outward and required considerable effort to open due to “differential pressure” inside and outside the spent fuel room. This differential pressure resulted from federal regulations that required maintaining the spent fuel room in a “negative pressure” state to facilitate 3 radiation monitoring and containment. The differential pressure varied “depend[ing] on . . . the alignment of the air of the ventilation systems” throughout the building. One Edison employee testified the differential pressure made it “a challenge for anybody other than a full-size football player to open [the door].” For this reason, in the 1990s Edison installed a “mechanical assistive device” — commonly called the “breaker bar” — to help pry the door open by breaking the differential pressure seal and allowing the door to open more easily. Edison records showed that the breaker bar sometimes broke but was working properly the day of the accident.

B. Cesena’s Accident

Cesena worked at SONGS consistently from 1994 to 2003, and on “temporary stints” in 2016 and 2017 before returning full-time in August of

2017.2 Upon her full-time return, Cesena underwent safety training and began a role requiring her to access the spent fuel room. Cesena worked at SONGS five to seven days per week and was “very familiar” with the spent fuel room. The accident occurred on December 2, 2017. Cesena was waiting to leave the spent fuel room and, as she typically did, asked a coworker to open the door for her. Cesena waited on the ramp’s flat, elevated walkway “above the slope” as her coworker Arturo — a “big guy” and “a boilermaker” — opened the exit door. Cesena described the accident at trial: “When he opened the door, . . . the wind came . . . towards us from the pressure. And I

2 In 2017 Cesena worked for a third-party contractor that Edison hired to perform decommissioning work. 4 saw him come towards me. And when he came towards me, I went back. And then I slipped on the ramp and I slammed on the wall.” The day after Cesena’s accident, SONGS workers replaced the nonslip tape strips on the ramp with wider strips that covered more of the ramp’s surface “for better footing.” As we discuss further below, it is essentially undisputed that there were no accidents on the ramp in the 18-plus-year period preceding Cesena’s accident.

C. Pretrial Proceedings

Cesena sued Edison for negligence, alleging that the pressurized door and the ramp were dangerous conditions. About a week before the initial trial date, Cesena moved in limine to “exclud[e] all testimony, references to testimony, or argument relating to the absence of evidence of prior incidents” at her accident site. She argued this evidence was irrelevant and was “not admissible to disprove the existence of a dangerous condition.” Cesena relied, in part, on Thompson v. B.F. Goodrich Co. (1941) 48 Cal.App.2d 723, in which a patron tripped over an elevated platform in a tire shop while stepping around “an easel-like advertising display rack.” (Id. at p. 726.) The appellate court in Thompson concluded the trial court properly excluded “evidence to the effect that many persons had passed [the relevant area] . . . and nobody had ever fallen over the platform before.” (Id. at p.
