Pedro Susano Herrera Marquez (Herrera) was injured on December 31, 2019, while operating a power press while working for Research Metal Industries, Inc. (RMI). The injury occurred when a power press ram used for stamping metal parts unexpectedly stroked downward while Herrera’s hand was beneath it. Herrera received workers’ compensation benefits for this injury.
According to a California Occupational Safety and Health Administration (Cal-OSHA) summary prepared after the accident occurred, “At the completion of [the press] stamping a piece of metal, the ram of the punch press returned to the up position. As [Herrera] went to remove the piece of stamped metal from the punch press’s tooling the punch press ram began its next cycle and came down onto [Herrera]’s left hand.” “The malfunctioning of [the press’s] air control valve did not allow the punch press[’]s ram to lock in position after its upright stroke.”
In December 2020, Herrera sued RMI as well as Doe defendants. Herrera asserted a single cause of action against RMI for negligence pursuant to Labor Code section 4558 alleging that RMI failed to repair, maintain, or retrofit the power press and “removed the point of operation guard from the subject power press, rendering the safeguarding mechanism dysfunctional or unavailable for use.”
Federal Press manufactured the subject press, a Federal Press No. 10, in or about 1967. RMI purchased the press at auction in or about 2010. A Federal Press catalog obtained by Herrera after the accident depicted the company’s model No. 10 as having a two-button operator control mounted directly on the machine. At the time of Herrera’s injury, the subject press did not have such an original mounted two-button control. Rather, the press was equipped with a two-button control on a movable pedestal. Generally, two-button controls keep the operator’s hands out of the area where the ram strikes the item being shaped.
RMI had a third party install the two-handed control system. The two-button control was mounted on a movable pedestal that could be “moved out” “about three feet” away from the press.
RMI moved for summary judgment which the trial court granted. It found that because RMI submitted evidence that a functional two-button control was in use at the time of Herrera’s injury, RMI shifted the burden to Herrera to demonstrate a triable issue. Herrera attempted to do so by arguing that the two-button control did not comply with the manufacturer’s design or state and federal regulations and that the solenoid air valve did not comply with point of operation guarding requirements.
The Court of Appeal affirmed (although for a different reason than that relied upon by the trial court) in the unpublished case of Herrera Marquez v. Research Metal Industries -B329641 (February 2025).
Labor Code section 4558 provides that an injured employee may sue his employer in tort when the injury “is proximately caused by the employer’s knowing removal of, or knowing failure to install, a point of operation guard on a power press.” This narrow exception limits tort liability to cases where “the manufacturer designed, installed, required, or otherwise provided by specification for the attachment of the guards and conveyed knowledge of the same to the employer.”
RMI argued Herrera could not adduce evidence that “the manufacturer designed, installed, required, or otherwise provided by specification for the attachment of [the] guards and conveyed knowledge of [the] same to [RMI]” as required under subdivision (c) of section 4558. Herrera argued RMI had failed to shift the burden to him to demonstrate a triable issue. “The parties (like the trial court did) focus on whether RMI’s independent installation of a two-button control means RMI failed to install or removed a point of operation guard.”
However, under section 4558, “the culpable conduct is the employer’s ignoring of the manufacturer’s safety directive.” (Aguilera v. Henry Soss & Co. (1996) 42 Cal.App.4th 1724, 1730; see Award Metals, Inc. v. Superior Court (1991) 228 Cal.App.3d 1128, 1134 [“From the plain language of section 4558, it is clear that an exception . . . only arises for a power press injury where the employer has been expressly informed by the manufacturer that a point of operation guard is required”].)
“Here, the summary judgment record shows that when RMI purchased the subject press at auction approximately 45 years after Federal Press had manufactured it, the press did not include a two-button hand control. Nor did RMI receive a Federal Press manual or other documentation at the time of purchase.
Thus, RMI made a prima facie showing that Federal Press did not convey any information to RMI concerning a point of operation guard. This shifted the burden to Herrera to demonstrate a triable issue of fact as to what Federal Press conveyed to RMI. He failed to do so.
Accordingly, Herrera failed to carry his burden to demonstrate a triable issue that Federal Press ‘designed, installed, required, or otherwise provided by specification for the attachment of the guards and conveyed knowledge of the same to [RMI].’ (§ 4558, subd. (c).) As this is dispositive, we need not consider Herrera”
