''Bauer v. Boeing'', No. 87593-1-I (Wash. Ct. App. Div. I, May 18, 2026), is a published Washington Court of Appeals decision holding that (1) Washington negligence law recognizes an employer's preconception duty of care to a not-yet-conceived offspring of its employee, subject to foreseeability limits, and (2) the exclusive-remedy provision of the Washington Industrial Insurance Act (IIA), Revised Code of Washington (RCW) 51.04.010, does not bar a subsequently conceived child's personal injury claim when the child's injuries are separate and distinct from the worker-parent's workplace injuries.

The case concerns Thomas Bauer, an electrical installer at the Boeing manufacturing plant in Everett, Washington, who was exposed to volatile organic solvents and heavy metals during commercial aircraft production. His son Milo Bauer was born in 2017 with permanent and disabling birth defects, including ventricular septal defect, tricuspid atresia, pulmonary stenosis, VACTERL syndrome, congenital hip dysplasia, ano-rectal malformation, urethral duplication, and spinal tethering. The Bauers alleged that Boeing had decades of internal awareness — including a 1986 internal toxicologist list of chemicals associated with developmental toxicity and 1996 memoranda on paternal organic solvent exposure and birth-defect potential — and yet failed to warn workers, prevent the exposures, monitor reproductive-harm risks, or offer less chemical-intensive work to employees attempting to have children.

The Court of Appeals, in an opinion authored by Judge Birk, unanimously affirmed the Snohomish County Superior Court's denial of Boeing's Civil Rule (CR) 12(b)(6) motion to dismiss and answered both certified questions in favor of the Bauer family. The decision returns the case to trial for proceedings on the merits.

Although the chemicals at issue in ''Bauer'' are aerospace solvents and heavy metals — not asbestos — the ruling extends Washington's take-home asbestos exposure doctrine line of authority (''Lunsford v. Saberhagen Holdings''; ''Arnold v. Saberhagen Holdings'') to the preconception scenario, and is directly relevant to mesothelioma plaintiffs evaluating whether IIA exclusivity bars a third-party or family-member claim against a Washington employer. For Washington asbestos and mesothelioma cases, ''Bauer'' confirms three things: the take-home doctrine cases remain controlling and unmodified; the IIA's exclusivity bar to family-member civil claims remains narrow and applies only to derivative claims (loss of consortium, NIED arising from the worker's injury); and the foreseeability framework that supports take-home liability also supports duty extension along other foreseeable chemical-exposure pathways when an employer has documented internal awareness of the hazard.

== Executive Summary ==

''Bauer v. Boeing'', No. 87593-1-I, is a 2026 Washington Court of Appeals decision that answers two questions of first impression for Washington tort law in the workplace chemical-exposure context. The first question is whether Washington recognizes an employer's preconception duty of care to the not-yet-conceived offspring of its employee. The court held that it does, subject to the same foreseeability limits the Washington Supreme Court established in ''Harbeson v. Parke-Davis, Inc.'', 98 Wn.2d 460, 656 P.2d 483 (1983), and reaffirmed in ''Pacheco v. United States'', 200 Wn.2d 171, 515 P.3d 510 (2022). The second question is whether the IIA's exclusive-remedy provision in RCW 51.04.010 — the "grand bargain" under which Washington workers surrender their common-law right to sue employers in exchange for guaranteed no-fault workers' compensation — bars the subsequently conceived child's civil personal injury claim. The court held it does not, applying the rule of ''Meyer v. Burger King Corp.'', 144 Wn.2d 160, 26 P.3d 925 (2001), that the IIA does not apply to third parties, family members, or dependents who themselves suffer an injury that is not legally dependent on the employee's workplace injury. The court relied substantially on Washington's take-home asbestos exposure line of authority — ''Lunsford v. Saberhagen Holdings, Inc.'', 125 Wn. App. 784, 106 P.3d 808 (2005), and ''Arnold v. Saberhagen Holdings, Inc.'', 157 Wn. App. 649, 240 P.3d 162 (2010) — for the foreseeability principle that an employer's chemical exposure of its workforce foreseeably reaches household members of those workers, and extended that principle to encompass the workers' subsequently conceived children. Although the ''Bauer'' chemicals at issue are aerospace solvents and heavy metals rather than asbestos, the ruling has direct implications for Washington asbestos and mesothelioma plaintiffs in two ways: it confirms the continued vitality of the take-home exposure doctrine cases in Washington, and it clarifies the doctrinal line between derivative family-member claims (barred by the IIA) and independent personal-injury claims of family members (not barred). The decision returns the case to the Snohomish County Superior Court for proceedings on the merits; Boeing's CR 12(b)(6) dismissal motion is denied.

== What Did the Court Decide in Bauer v. Boeing? ==

''Bauer v. Boeing'' answered two certified questions of law on discretionary review from the Snohomish County Superior Court's denial of Boeing's CR 12(b)(6) motion to dismiss. Both questions were resolved in favor of the Bauer family.

''Certified Question 1: Does Washington law recognize a duty on the part of an employer to the not-yet-conceived offspring of its employees (a "preconception" duty)?'' The Court of Appeals held: yes, subject to foreseeability limits. The duty is grounded in the Washington Supreme Court's decision in ''Harbeson v. Parke-Davis, Inc.'', 98 Wn.2d 460, 656 P.2d 483 (1983), in which the court held that "a duty may extend to persons not yet conceived at the time of a negligent act or omission" and that the duty is "limited, like any other duty, by the element of foreseeability." ''Harbeson''′s reach is not confined to the healthcare context — the court there said the duty applies to "[a] provider of health care, ''or anyone else''" who foreseeably endangers others (emphasis in original). The Court of Appeals in ''Bauer'' read this language as plainly extending beyond healthcare and rejected Boeing's narrower reading.<ref name="bauer_slip_op" /><ref name="harbeson_1983" />

''Certified Question 2: Does the IIA's exclusivity provision (RCW 51.04.010) bar the claim when it arises from an occupational disease impairing the employee's reproductive system?'' The Court of Appeals held: no. The IIA bars only claims by family members that are "logically or legally dependent" on the worker's injury — derivative claims like loss of consortium or negligent infliction of emotional distress arising from the worker's injury. The IIA does not bar claims that the family member brings for separate, personal injuries that are causally connected to, but legally independent of, the worker's injury. Applying ''Meyer v. Burger King Corp.'', 144 Wn.2d 160, 26 P.3d 925 (2001), the Court of Appeals found that Milo's congenital birth defects are separate and distinct injuries from Thomas's workplace injury (damage to his reproductive system) — and therefore not derivative.<ref name="bauer_slip_op" /><ref name="meyer_burger_king_2001" />

The disposition: affirmed. The Snohomish County Superior Court's denial of Boeing's CR 12(b)(6) motion is upheld. The case returns to the trial court for proceedings on the merits.<ref name="bauer_slip_op" />

== What Are the Facts of Bauer v. Boeing? ==

''The facts below are drawn from the Bauers' complaint and treated as true for purposes of Boeing's CR 12(b)(6) motion. They are allegations, not findings of fact after trial.''

Thomas Bauer is an electrical installer at the Boeing manufacturing plant in Everett, Washington, where he has worked since 2011. The complaint alleges that, as part of his work, Thomas is regularly exposed to "a mixture of chemicals that, individually and collectively, are capable of harming the unborn child and future offspring, including through genetic, epigenetic and/or other mechanisms that damage sperm and/or otherwise impair the processes of conception and pregnancy." The chemicals include volatile organic solvents and heavy metals, with exposure through inhalation, ingestion, and dermal contact.<ref name="bauer_slip_op" />

Thomas and Teela Bauer conceived their son Milo while Thomas was working at Boeing's Everett facility. Milo was born in 2017 with permanent and disabling birth defects: ventricular septal defect, tricuspid atresia, pulmonary stenosis, VACTERL syndrome, congenital heart anomalies, congenital hip dysplasia, ano-rectal malformation, urethral duplication, and spinal tethering.<ref name="bauer_slip_op" />

The complaint alleges that Boeing had decades of internal awareness that paternal workplace chemical exposures could cause birth defects. Specific allegations include peer-reviewed epidemiological studies since the 1970s linking paternal occupational exposures to birth defects; scientific recognition since at least 1980 of genetic damage to unborn children from paternal chemical exposures; testimony that a Boeing corporate representative acknowledged the company's awareness no later than 1984; a 1986 internal list maintained by Boeing toxicologists identifying chemicals associated with developmental toxicity that included chemicals Thomas worked with; 1996 Boeing toxicologist memoranda addressing paternal organic solvent exposure and birth-defect potential; and a 1999 State of Washington booklet acknowledging that preconception exposure in men may affect child development.<ref name="bauer_slip_op" />

The complaint further alleges that Boeing failed to provide adequate warnings, education, and training; failed to prevent chemical exposures; failed to monitor and investigate reproductive harm risks; and failed to offer less chemical-intensive assignments to workers attempting to have children.<ref name="bauer_slip_op" />

== How Did the Court Analyze the Preconception Duty? ==

The Washington negligence framework requires four elements: duty, breach, injury, and proximate cause. ''Degel v. Majestic Mobile Manor, Inc.'', 129 Wn.2d 43, 48, 914 P.2d 728 (1996). The existence and scope of a duty are questions of law, determined by weighing logic, common sense, justice, policy, and precedent. ''Centurion Props. III, LLC v. Chicago Title Ins. Co.'', 186 Wn.2d 58, 65, 375 P.3d 651 (2016).<ref name="bauer_slip_op" />

The Court of Appeals identified three converging lines of authority supporting recognition of an employer's preconception duty.

''Harbeson v. Parke-Davis, Inc.'', 98 Wn.2d 460, 656 P.2d 483 (1983), is the foundational Washington preconception duty case. The plaintiff was prescribed the anticonvulsant Dilantin (phenytoin) during three pregnancies; two children were born with fetal hydantoin syndrome. The Washington Supreme Court held that "a duty may extend to persons not yet conceived at the time of a negligent act or omission. Such a duty is limited, like any other duty, by the element of foreseeability." The court further stated that "a provider of health care, or anyone else, will be liable only to those persons foreseeably endangered by this conduct" (emphasis in original) — the "or anyone else" phrasing that the ''Bauer'' court read as extending the duty beyond the healthcare context.<ref name="harbeson_1983" />

''Pacheco v. United States'', 200 Wn.2d 171, 515 P.3d 510 (2022), reaffirmed ''Harbeson''. A healthcare provider mistakenly administered the wrong injection (not the intended contraceptive); the patient later gave birth to a child with a congenital defect and permanent disabilities. The Washington Supreme Court adopted the umbrella term "negligent reproductive healthcare," awarded $2.5 million in emotional distress damages, and noted that "no one suggests that we should disavow ''Harbeson'' now, and the approach we took there shows a clear intent to apply negligence principles equitably." The ''Bauer'' court read ''Pacheco'' as not limiting ''Harbeson'' to medical contexts.<ref name="pacheco_2022" />

The court also drew on Washington's own take-home asbestos exposure line of authority. ''Lunsford v. Saberhagen Holdings, Inc.'', 125 Wn. App. 784, 106 P.3d 808 (2005), extended an asbestos manufacturer's strict liability to the child of a worker who carried asbestos fibers home on clothing. ''Arnold v. Saberhagen Holdings, Inc.'', 157 Wn. App. 649, 240 P.3d 162 (2010), recognized a shipyard operator's duty to prevent take-home asbestos exposure to household members of an independent contractor's employee. The ''Bauer'' court reasoned: "It is just as foreseeable that workers, in general, will conceive children within their household."<ref name="lunsford_2005" /><ref name="arnold_2010" /><ref name="bauer_slip_op" />

Boeing's principal counterarguments — that preconception duty exists only in healthcare; that the court should follow California's ''Elsheref v. Applied Materials'', 223 Cal. App. 4th 451 (2014); that recognizing the duty would create unpredictable downstream liability; that employers would be forced to interrogate employees about reproductive plans; that claims would involve complex science and be stale and meritless; and that only misfeasance can give rise to liability — were each rejected. The court noted that ''Elsheref'' relied on ''Oddone v. Superior Court'', which the California Supreme Court itself later disapproved in ''Kesner v. Superior Court'', 1 Cal. 5th 1132 (2016) (recognizing a take-home asbestos duty limited to household members). Concerns about liability "run amok" can be addressed through conventional concepts of the measure and scope of a duty of care; employers need only fully inform employees of risks and not act negligently (''Meyer v. Burger King Corp.'', 144 Wn.2d at 170); and "difficulty of proof does not prevent the assertion of a legal right."<ref name="bauer_slip_op" /><ref name="kesner_2016" /><ref name="meyer_burger_king_2001" />

The court grounded its public-policy analysis in Washington Constitution Article II, Section 35, which mandates that the legislature "shall pass necessary laws for the protection of persons working in mines, factories and other employments dangerous to life or deleterious to health" — what the Washington Supreme Court has called "a fundamental right of Washington workers to health and safety protection." ''Martinez-Cuevas v. DeRuyter Bros. Dairy, Inc.'', 196 Wn.2d 506, 520, 475 P.3d 164 (2020).<ref name="wa_const_art_II_35" /><ref name="bauer_slip_op" />

The duty is limited by foreseeability to the worker's immediate offspring — not extended to remote or unforeseeable plaintiffs. The foreseeability anchor is analogous to the California Supreme Court's limit in ''Kesner'' to household members.<ref name="bauer_slip_op" /><ref name="kesner_2016" />

== How Does the IIA Exclusive-Remedy Provision Apply Here? ==

RCW 51.04.010, enacted in 1911 and amended in 1961, 1972, and 1977, is the cornerstone of the Washington Industrial Insurance Act (IIA), Title 51 RCW. It establishes the "grand bargain": workers surrender their common-law right to sue employers for workplace injuries in exchange for guaranteed no-fault workers' compensation administered through the Washington Department of Labor and Industries (L&I). The statute declares that all civil actions and civil causes of action for workplace personal injuries are "abolished" except as the title provides.<ref name="rcw_51_04_010" /><ref name="title_51_rcw" />

The IIA's exclusivity bar reaches more than the worker's own civil claim. It also bars certain civil claims by family members of injured workers — those that are "logically or legally dependent" on the worker's injury. The doctrinal line is between derivative claims (barred) and independent claims (not barred):<ref name="bauer_slip_op" />

* '''Derivative claims (barred):''' Loss of consortium, negligent infliction of emotional distress (NIED) arising from the worker's injury, and other claims whose viability depends on proving the worker's compensable workplace injury. Examples: ''West v. Zeibell'', 87 Wn.2d 198, 550 P.2d 522 (1976) (parents' wrongful death claim barred); ''Provost v. Puget Sound Power & Light Co.'', 103 Wn.2d 750, 696 P.2d 1238 (1985) (wife and child's NIED and loss of consortium claims barred).<ref name="west_v_zeibell_1976" /><ref name="provost_1985" />

* '''Independent claims (not barred):''' Claims for personal injuries to the family member that are causally connected to, but legally independent of, the worker's injury. The dispositive Washington case is ''Meyer v. Burger King Corp.'', 144 Wn.2d 160, 26 P.3d 925 (2001), in which a 35-week-pregnant Burger King employee struck her abdomen on a table corner; her child Patricia was later born with massive brain damage from oxygen deprivation due to placental abruption. The Washington Supreme Court held Patricia's injuries (brain damage) were "separate and distinct" from the mother's injuries (uterine and placental trauma): "While the mother and child in utero are physically connected, an injury to one is not necessarily an injury to the other." The court stated the controlling rule: "The [IIA] does not apply to third parties, family or dependents, who themselves suffer an injury not legally dependent on the employee's injury."<ref name="meyer_burger_king_2001" />

The ''Bauer'' court applied ''Meyer''′s reasoning to the preconception scenario. Boeing argued that ''Meyer'' was distinguishable because Patricia was in utero at the worksite, whereas Milo was conceived only after Thomas's exposures. The court rejected the distinction: "Boeing's argument is essentially a retread of the same argument rejected in ''Meyer'' — that the child's injuries are a causal result of the parent's injuries." Thomas's injury (damage to his reproductive system) and Milo's injuries (congenital birth defects) are causally connected but separate and distinct injuries; Milo's injuries are "personal to him."<ref name="bauer_slip_op" />

The IIA's exclusive-remedy provision therefore does not bar Milo's civil claim against Boeing. Thomas's own claim for any reproductive-system occupational disease remains an IIA matter handled through L&I; the two pathways operate in parallel.

== How Does Bauer Connect to Take-Home Asbestos Doctrine? ==

''Bauer'' is not a mesothelioma case, but it sits directly on the doctrinal foundation that Washington's take-home asbestos cases established. The take-home doctrine recognizes that an asbestos manufacturer, premises owner, or employer may owe a duty of care to household members of workers whose chemical exposures travel home on clothing, hair, skin, and tools — exposures that have, for decades, been a documented pathway to mesothelioma diagnoses in spouses, children, and other co-residents of asbestos workers. See [[Secondary_Asbestos_Exposure]] for the broader framework.

In ''Lunsford'', the court extended an asbestos manufacturer's strict liability to the child of a worker who carried asbestos fibers home on his work clothing. In ''Arnold'', the court recognized a shipyard operator's duty to prevent take-home asbestos exposure to household members of an independent contractor's employee. The doctrinal point is foreseeability: the manufacturer and premises owner foresee that fibers will leave the workplace on a worker's clothing and that household members will be exposed.<ref name="lunsford_2005" /><ref name="arnold_2010" />

The ''Bauer'' court used the same foreseeability principle to extend duty to the worker's not-yet-conceived offspring: it is just as foreseeable that workers will conceive children within their household as it is that workers will have household members exposed via take-home pathways. The chemicals at issue in ''Bauer'' are aerospace solvents and heavy metals rather than asbestos, but the doctrinal step — extending the duty along a foreseeable, biologically plausible exposure pathway — is the same step Washington courts took in the take-home asbestos line.<ref name="bauer_slip_op" />

The companion case ''Quinn v. GE'' (Maryland, 2026) addresses parallel third-party/take-home duty doctrine from a different state jurisdiction. A dedicated WikiMesothelioma page on ''Quinn'' is a planned follow-on; the cross-jurisdiction comparison will be added once both pages are live.

== What Does Bauer Mean for Mesothelioma Plaintiffs in Washington? ==

''Bauer'' has three direct implications for Washington asbestos and mesothelioma plaintiffs and the attorneys evaluating their claims.

''First, the IIA exclusivity bar to civil claims by family members remains narrow under Washington law.'' A spouse or child diagnosed with mesothelioma decades after take-home exposure to a Washington asbestos worker's clothing is not bringing a derivative claim — they are bringing a claim for their own personal injury caused by the employer or premises owner's failure to control fiber release. The ''Meyer'' / ''Bauer'' line of authority confirms that such claims are not barred by RCW 51.04.010. The worker's own claim for asbestos-related occupational disease remains an L&I matter; the family member's claim proceeds in civil court.

''Second, the take-home doctrine cases (''Lunsford'' and ''Arnold'') remain controlling.'' ''Bauer'' did not modify or limit these holdings — it relied on them as the foreseeability foundation for the preconception extension. Counsel for Washington mesothelioma plaintiffs evaluating take-home or secondary exposure claims can continue to rely on the ''Lunsford'' / ''Arnold'' framework.<ref name="lunsford_2005" /><ref name="arnold_2010" />

''Third, the foreseeability anchor for duty is grounded in the employer's documented internal awareness of the exposure hazard.'' The ''Bauer'' complaint's allegations of decades of Boeing internal knowledge of paternal-exposure birth-defect risk were factually parallel to the historical record of asbestos manufacturer and employer knowledge of mesothelioma risk — knowledge that has been documented across decades of asbestos litigation discovery. The doctrinal lesson is that ''documented internal knowledge of the hazard, coupled with foreseeable exposure pathways to a defined class of foreseeable plaintiffs, supports recognition of a duty of care'' — the same framework that has long supported take-home asbestos liability in Washington.<ref name="bauer_slip_op" />

== What Does Bauer Not Decide? ==

''Bauer'' is procedurally a CR 12(b)(6) ruling on certified questions of law. It does not decide the merits of the Bauer family's negligence claim. Several factual and legal questions remain for resolution at trial or in subsequent proceedings:<ref name="bauer_slip_op" />

* '''Breach.''' Whether Boeing's specific conduct — including its knowledge, training programs, hazard communication, and chemical-control measures at the Everett facility during the relevant period — fell below the standard of care.

* '''Causation.''' Whether Thomas's chemical exposures caused damage to his reproductive system; whether that damage caused Milo's specific congenital birth defects; and what the relative contribution of preconception vs. postconception vs. genetic/familial factors is to the cluster of conditions Milo presents.

* '''Damages.''' The scope and measure of damages for Milo's permanent disability, and any independent damages of Teela and Thomas Bauer as guardians and parents.

* '''Defendant-specific liability.''' The complaint named several co-defendants (Exotic Metals Forming, Giddens Industries/Cadence Aerospace, Hytek Finishes, Newco/Newco Columbia, Toray Composites) in addition to Boeing; the certified questions addressed Boeing as employer, but the duty analysis as to non-employer co-defendants will involve distinct doctrinal frameworks.

* '''Scope of duty in non-employment chemical-exposure contexts.''' The duty recognized in ''Bauer'' is an employer's duty to its employee's not-yet-conceived offspring. The ruling does not directly resolve duty questions for chemical manufacturers, landlords, or others who are not the worker's employer. Those questions will turn on the same foreseeability analysis but with different doctrinal anchors.

The ruling is also subject to potential further review by the Washington Supreme Court. Boeing may petition for discretionary review; the Washington Supreme Court has discretion whether to accept the case.

== Compensation, Trust Funds, and Legal Resources for Washington Asbestos Plaintiffs ==

Washington mesothelioma plaintiffs typically pursue compensation through multiple parallel pathways. Asbestos trust funds — established under Section 524(g) of the U.S. Bankruptcy Code — currently hold an aggregate of approximately $30 billion to compensate mesothelioma patients exposed to manufacturers who have since filed for bankruptcy. Filing against active trusts requires documentation of asbestos exposure history and a confirmed mesothelioma diagnosis with histologic subtyping. See [[Asbestos_Trust_Funds]] for the trust framework.

For workers covered by the Washington IIA, the worker's own claim for asbestos-related occupational disease is administered by the Washington Department of Labor and Industries through Title 51 RCW. The IIA's no-fault structure provides medical and disability benefits without requiring proof of employer fault. For family members or third parties suffering separate, personal injuries (such as a spouse who developed mesothelioma from take-home exposure), the ''Meyer'' / ''Bauer'' line confirms that civil claims against the employer remain available because such injuries are independent of the worker's IIA-compensable injury.<ref name="title_51_rcw" /><ref name="meyer_burger_king_2001" /><ref name="bauer_slip_op" />

Outside the IIA framework, plaintiffs may pursue product liability claims against asbestos manufacturers and their successors, and premises liability claims against site owners whose negligence permitted asbestos exposure. The take-home doctrine cases (''Lunsford''; ''Arnold'') govern third-party take-home exposure claims.

== Frequently Asked Questions ==

=== Can Boeing workers sue for asbestos-related injuries in Washington? ===

The Washington Industrial Insurance Act (IIA), RCW 51.04.010, generally provides the exclusive remedy for a worker's own workplace injuries and occupational diseases — including asbestos-related diseases such as mesothelioma, asbestos-related lung cancer, and asbestosis. The worker files a Department of Labor and Industries (L&I) occupational disease claim. However, ''Bauer v. Boeing'' confirms that family members suffering separate, personal injuries causally connected to the workplace exposure may bring civil claims against the employer — such claims are not barred by IIA exclusivity because they are not legally dependent on the worker's injury. Outside the employment relationship, claims against asbestos product manufacturers and premises owners proceed under standard product liability and premises liability law.<ref name="rcw_51_04_010" /><ref name="bauer_slip_op" /><ref name="meyer_burger_king_2001" />

=== What is the Washington IIA exclusivity rule for chemical exposure? ===

RCW 51.04.010 establishes that all civil actions and civil causes of action for workplace personal injuries are "abolished" except as Title 51 provides. The worker's exclusive remedy is the IIA workers' compensation system, administered by the Washington Department of Labor and Industries. The IIA also bars derivative civil claims by family members — claims that are logically or legally dependent on the worker's workplace injury (e.g., loss of consortium, NIED arising from the worker's injury). The IIA does not bar claims by family members for separate, personal injuries that are causally connected to, but legally independent of, the worker's injury (''Meyer v. Burger King Corp.''; ''Bauer v. Boeing'').<ref name="rcw_51_04_010" /><ref name="meyer_burger_king_2001" /><ref name="bauer_slip_op" />

=== Does Washington workers' comp cover birth defects from chemical exposure? ===

A worker's own injury claim — including reproductive-system damage from chemical exposure — is administered through the L&I occupational disease system under Title 51 RCW. The child's separate personal injury (the birth defects themselves) is not the worker's injury and is therefore not within the IIA system. ''Bauer v. Boeing'' confirms that the child may bring a civil tort claim against the employer for birth defects caused by the employer's negligent chemical exposure of the worker-parent, and that the IIA exclusivity provision does not bar that claim.<ref name="bauer_slip_op" /><ref name="title_51_rcw" />

=== What did the Bauer v. Boeing 2026 ruling decide? ===

The Washington Court of Appeals, Division I, in a published opinion authored by Judge Birk filed May 18, 2026 (No. 87593-1-I), affirmed the Snohomish County Superior Court's denial of Boeing's CR 12(b)(6) motion to dismiss. The court answered two certified questions: (1) Washington law recognizes an employer's preconception duty of care to the not-yet-conceived offspring of its employees, limited by foreseeability per ''Harbeson v. Parke-Davis, Inc.'' (1983) and ''Pacheco v. United States'' (2022); and (2) the IIA's exclusive-remedy provision (RCW 51.04.010) does not bar the child's civil claim because the child's injuries are separate and distinct from the worker-parent's injuries per ''Meyer v. Burger King Corp.'' (2001). The case returns to the trial court for proceedings on the merits.<ref name="bauer_slip_op" />

=== How does Bauer connect to take-home asbestos exposure cases? ===

''Bauer'' relies directly on Washington's take-home asbestos exposure line of authority — ''Lunsford v. Saberhagen Holdings'' (2005) and ''Arnold v. Saberhagen Holdings'' (2010) — for the foreseeability principle that workplace chemical exposure foreseeably reaches household members, including the worker's children. The court extended that principle to the worker's not-yet-conceived offspring on the reasoning that it is just as foreseeable that workers will conceive children within their household as it is that workers will have household members exposed via take-home pathways. The ruling reinforces the continued vitality of the take-home doctrine in Washington.<ref name="lunsford_2005" /><ref name="arnold_2010" /><ref name="bauer_slip_op" />
