Limited Undertaking, Limited Duty: Vendor Pump Training Does Not Create a General Workplace-Safety Duty Under Restatement § 324A

Introduction

This appeal arose from a fatal fire in a paint-mixing room at the Letterkenny Army Depot in Pennsylvania. The Depot used pumps to transfer paint and paint thinner from drums into a mixing system. Finishing Systems was hired to upgrade pumps; its subcontractor purchased pumps from Carlisle Fluid Technologies. Carlisle installed the pumps and provided short, basic instruction on operation and maintenance.

Two months later, a worker opened an “empty” thinner drum, vapors escaped, and a static discharge allegedly ignited a fire. Two workers died and another was severely burned; others claimed emotional distress. Plaintiffs sued multiple defendants, but on appeal only claims against Carlisle remained—principally that Carlisle negligently failed to provide adequate safety training.

The central legal issue was duty: whether Carlisle’s limited contractual undertaking to install equipment and “assist and train” personnel on “use, care and maintenance” created a broader tort duty under Pennsylvania law (Restatement (Second) of Torts § 324A) to train workers comprehensively about workplace safety hazards (notably anti-static clothing and flammable vapors).

Summary of the Opinion

Judge Bibas, writing for the panel, affirmed summary judgment for Carlisle. Applying Pennsylvania law, the Court held that Carlisle owed no duty to provide comprehensive safety training because it never undertook that responsibility. Carlisle agreed to sell and install pumps and to provide basic training on “use, care and maintenance,” which it did (roughly 30 minutes to two hours of operational instruction). The record did not show that Carlisle:

• negligently performed its undertaking in a way that increased the risk of harm,
• assumed the Depot’s independent duty to provide workplace safety training, or
• induced reliance such that the Depot or employees forgone safety measures expecting Carlisle to provide them.

Plaintiffs’ attempt to expand duty based on Carlisle’s “superior knowledge” of hazards and its provision of manuals/warnings failed because § 324A liability turns on the undertaking, not generalized expertise or foreseeability untethered to an assumed service.

Analysis

Standard of review and the “duty” question

The Court reiterated that whether a defendant owed a duty is reviewed de novo at summary judgment, citing Tundo v. County of Passaic, 923 F.3d 283, 286-87 (3d Cir. 2019). This framed duty as a threshold legal issue: absent duty, negligence claims fail regardless of tragedy or causation disputes.

Pennsylvania’s adoption of Restatement § 324A (negligent undertaking)

The Court relied on Cantwell v. Allegheny County, 483 A.2d 1350, 1353 (Pa. 1984) for the proposition that Pennsylvania follows the Second Restatement. The operative doctrine was Restatement (Second) of Torts § 324A: one who undertakes to render services to another may be liable to third persons for negligent performance in limited circumstances.

Importantly, the Court emphasized (with a “Cf.” cite) Sheridan v. NGK Metals Corp., 609 F.3d 239, 263 (3d Cir. 2010) for the limiting principle: the duty extends no further than the undertaking itself. This is the opinion’s organizing idea and the axis on which all three § 324A pathways turn.

§ 324A(1): “increased risk of harm” requires making things worse

The Court used Restatement illustrations to show what counts as increasing risk (e.g., negligent dispatching causing a train wreck; careless repair causing a fixture to fall). It then anchored the point with Alderwoods (Pa.), Inc. v. Duquesne Light Co., 106 A.3d 27, 29-30, 42 (Pa. 2014), where negligent repair contributed to a fire. Those examples share a feature missing here: the defendant’s performance introduced or aggravated a hazard (a misrepair, defective fix, or negligent operational control).

Carlisle’s installation and training did not allegedly malfunction, misrepair, or create a new ignition risk; plaintiffs’ theory was essentially an omission—failure to provide broader safety training. The Court treated that as not fitting § 324A(1) absent proof that Carlisle’s performance made the situation more dangerous than if Carlisle had not acted.

§ 324A(2): assuming another’s duty requires a specific undertaking—often contract-defined

The Court explained that assumption of duty is usually defined by contract terms and closely tied to the services voluntarily undertaken. The key workplace-safety comparison was Farabaugh v. Pa. Tpk. Comm'n, 911 A.2d 1264, 1268-69, 1283 (Pa. 2006), where a contractor explicitly agreed to monitor jobsite safety and thus owed duties to workers.

The opinion then drew a boundary by citing Farabaugh’s distinction from Marshall v. Port Auth. of Allegheny Cnty., 568 A.2d 931, 936-37 (Pa. 1990): where a contractor did not agree to assure compliance with safety procedures, no duty arose. This contrast did the main analytical work: Carlisle’s undertaking resembled the “no assumed safety compliance” side of the line.

§ 324A(3): reliance is limited to what was promised

The Court collected reliance cases to show that an undertaking both creates and limits duty:

• Feld v. Merriam, 485 A.2d 742, 746-47 (Pa. 1984): a landlord who voluntarily provides security owes a duty to do what it promised—but tenants cannot expect more (one guard is not two).
• Evans v. Otis Elevator Co., 168 A.2d 573, 575-76 (Pa. 1961): an elevator inspector owes a duty to inspect with reasonable care within the scope of the inspection services.
• Scampone v. Grane Healthcare Co., 169 A.3d 600, 618-19 (Pa. Super. Ct. 2017): promised ongoing oversight of patient care created duties to perform that oversight reasonably.

For workplace inspections, the Court emphasized that limited safety-related services do not become general guardianship:

• Evans v. Liberty Mut. Ins. Co., 398 F.2d 665, 667 (3d Cir. 1968): insurer inspections/advice do not create a duty to identify every hazard (such as a missing machine guard) absent an undertaking to do so.
• Walls v. FTS Int'l, Inc., 2019 WL 96247, at *4-5 (W.D. Pa. Jan. 2, 2019): general training materials and guidance did not create a duty to ensure overall workplace safety.

Plaintiffs’ contrary authority—K.H. ex rel. H.S. v. Kumar, 122 A.3d 1080, 1096-97 (Pa. Super. Ct. 2015)—was distinguished as resting on the special doctor-patient relationship, not a generic undertaking theory. The Third Circuit used Kumar to sharpen a doctrinal boundary: some duties arise from status-based special relationships; Carlisle had no comparable relationship with Depot employees.

2) Legal Reasoning

The Court’s reasoning proceeds in disciplined Restatement steps.

a) The undertaking defines the duty (and its limits)

Carlisle’s contract language—“assist and train … personnel in the correct use, care and maintenance of the equipment”—was treated as an operational undertaking. The opinion accepts that Carlisle did provide basic instruction (how to start the pump, read gauges, adjust pressures, and transfer material). But it rejects the idea that this operational instruction silently included comprehensive fire-prevention training about flammable vapors and anti-static apparel.

Two specific arguments for expanding duty were rejected:

• “Superior knowledge” does not expand the undertaking. Even if Carlisle knew more about pump-related hazards, § 324A liability attaches to what services the defendant undertook to render, not merely to the defendant’s expertise or the foreseeability of harm.
• Manuals and general warnings do not convert limited training into broad safety oversight. Providing materials or encouraging training does not itself amount to Carlisle assuming the employer’s general obligation to run a safe facility.

b) Why each § 324A pathway failed on this record

• Increased risk (§ 324A(1)): Plaintiffs did not allege that Carlisle’s installation or maintenance work was defective or created a new hazard (e.g., sparks, leaks, miswiring). The alleged wrong was an omission—failure to teach broader safety. The Court treated that as not “increasing” risk absent evidence that Carlisle’s conduct left workers worse off than if Carlisle had never been involved.
• Assumption of another’s duty (§ 324A(2)): The Depot’s duty (if any) to train workers about handling flammable thinners remained with the Depot because Carlisle did not specifically undertake to ensure safety compliance in the paint room. Like the “no duty” contractor in Farabaugh’s distinction from Marshall, Carlisle’s agreement was limited to equipment operation and maintenance.
• Reliance (§ 324A(3)): There was no showing that the Depot or employees abandoned other safety measures because they relied on Carlisle to provide comprehensive safety training. And even if some reliance existed, Feld’s logic limits reliance to what was promised: one cannot reasonably rely on short equipment-operation instruction to substitute for an employer’s comprehensive fire and static-control program.

c) The opinion’s policy posture: tort duty is not a tragedy-driven solvent

The opening admonition—“tragedy does not create duty”—signals a policy throughline: negligence law must maintain stable duty boundaries so that liability tracks voluntary undertakings and recognized relationships, not the magnitude of harm. The Court’s approach keeps § 324A from becoming a general “deep-pocket” doctrine against vendors who enter worksites to install and demonstrate equipment.

3) Impact

Practical implications for vendors, contractors, and employers

• Equipment vendors who provide start-up training gain a clearer safe harbor: In Pennsylvania (as predicted by this Third Circuit interpretation), brief operational training and manuals will not, without an explicit undertaking, transform the vendor into a workplace-safety guarantor.
• Contracts and scopes of work will matter even more: Farabaugh remains the warning case—if a contractor expressly undertakes safety monitoring/oversight, tort duties to third parties expand accordingly. Post-Byers, parties can expect sharper litigation focus on written scope language (e.g., “safety compliance,” “hazard analysis,” “OSHA training,” “static-control procedures”).
• Plaintiff theories may pivot to product warnings/design or employer negligence: Because negligent-undertaking duty is confined, future plaintiffs may more aggressively plead failure-to-warn (product liability), negligent design, or premises/employer-based duties where the legal responsibility for safety training more naturally resides.
• Reliance must be evidenced, not presumed: The decision reinforces that reliance under § 324A(3) is fact-specific—courts will look for proof that the plaintiff (or the party receiving services) actually changed behavior because of the defendant’s undertaking.

Doctrinal implications

• Re-centering § 324A on “undertaking” rather than “foreseeability”: The Court’s rejection of “superior knowledge” as a duty-expander signals resistance to sliding from undertaking into generalized foreseeability-based duty in contractor/vendor contexts.
• Clear separation of special-relationship duties: By distinguishing Kumar, the Court underscores that status-based duties (doctor-patient) should not be imported into commercial installation/training relationships absent a recognized special relationship.

Complex Concepts Simplified

• “Duty” (in negligence): A legal obligation to act with reasonable care toward another. Without duty, a negligence claim fails even if harm was foreseeable and severe.
• Summary judgment: A ruling without trial when no genuine dispute of material fact exists and the moving party is entitled to judgment as a matter of law. Here, the key “law” question was duty.
• Restatement (Second) of Torts § 324A (“negligent undertaking”): If you voluntarily take on services for someone, you may owe duties to third persons harmed by your negligent performance—but typically only if (1) you made the situation more dangerous, (2) you took over someone else’s duty, or (3) others relied on your undertaking.
• “Scope of the undertaking”: The specific services you agreed (explicitly or through conduct) to provide. The undertaking is both the source and the boundary of any § 324A duty.
• “Reliance” under § 324A: The injured party (or the party receiving services) must have actually depended on the defendant’s promised services and changed behavior accordingly (e.g., skipped other safety measures).
• “Special relationship”: Certain relationships (like doctor-patient) can create affirmative duties that do not depend on a contractual undertaking. The Court held no such relationship existed between an equipment manufacturer and workplace employees.

Conclusion

The Third Circuit’s decision reinforces a crisp rule for negligent-undertaking claims under Pennsylvania law: liability to third parties tracks the defendant’s actual undertaking, not the magnitude of the harm, the defendant’s expertise, or generalized safety foreseeability. Because Carlisle undertook only to install pumps and provide basic operational instruction, and because none of § 324A’s three liability pathways (increased risk, assumption of duty, or reliance) was satisfied, Carlisle owed no duty to provide comprehensive workplace-safety training. The opinion thus tightens the doctrinal boundary between operational vendor support and true safety oversight—and signals that, absent a specific undertaking, “tragedy does not create duty.”
