De Laval Steam Turbine Asbestos Exposure
De Laval Steam Turbine Company made turbines, pumps, gears and other industrial and naval machinery. A New Jersey appellate opinion concerning its successor, IMO Industries, reports that some components in De Laval products made from the 1940s through the 1980s contained asbestos. The record supports investigation of particular equipment and work, not an assumption that every De Laval turbine or installation contained asbestos.
For a person who serviced steam machinery, the useful questions are which unit was involved, what material was disturbed, who supplied it and when the work occurred. This guide separates De Laval’s documented history from possible exposure through original parts, replacement materials and surrounding equipment.
🏢 De Laval Steam Turbine Company History
The 2014 appellate decision in IMO Industries Inc. v. Transamerica Corp. traces IMO’s origins to the Delaval Steam Turbine Company in 1901. It describes production of turbines, pumps, gears and machinery for industrial and military applications, including U.S. Navy ships. The opinion uses “Delaval”; the heading here follows the commonly searched “De Laval” spelling. Historical name variations matter when searching drawings, invoices or older legal records.
| Period | Documented development | Research implication |
|---|---|---|
| 1901 | Company began as Delaval Steam Turbine Company. | Search older files under Delaval. |
| 1940s–1980s | Some product components contained asbestos. | Identify the particular model and component. |
| 1963 | Transamerica acquired Delaval. | Use acquisition dates to interpret records. |
| 1986 | Business was spun off and became IMO Industries. | Later records may use IMO’s name. |
| Name in a file | Possible meaning | Further check |
|---|---|---|
| Delaval or De Laval | Historic manufacturer or brand. | Read equipment plate and purchase order. |
| Transamerica subsidiary | Corporate ownership during part of the history. | Confirm relevant subsidiary and year. |
| IMO Industries | Later corporate name described by court. | Trace the equipment and legal entity. |
| Another supplier | Contractor or maker of a nearby material. | Separate its work from De Laval’s. |
The decision concerns allocation of insurance responsibilities after asbestos claims. It is a useful company-history source, but it does not decide whether any particular person’s disease resulted from a specific De Laval unit. Company ownership, a recognizable nameplate and evidence of exposure each answer a different question.
Search under both the old company name and IMO when requesting archival drawings. A machine could have been built before a corporate change and repaired afterward. Record the date printed on each document so a later maintenance entry is not mistaken for the original equipment specification.
⚙️ Turbines, Pumps and Potential Asbestos Materials
Steam turbines operate in high-temperature systems. Historically, asbestos appeared in some insulation, gaskets and packing because it resisted heat; EPA describes these broader uses. The appellate record goes further for this company by identifying asbestos-containing components in some De Laval products. Neither source identifies every model, component, replacement part or period of use at a specific job site.
| Location | Material to investigate | Key distinction |
|---|---|---|
| Turbine casing | Thermal covering or removable insulation. | Confirm installer and material maker. |
| Flanged connection | Gasket removed during opening. | Original and replacement parts may differ. |
| Pump shaft | Packing changed during maintenance. | Find pump model and packing supplier. |
| Steam piping | Pipe covering near the machinery. | Nearby material need not be a De Laval product. |
| Equipment enclosure | Insulation or other protective material. | Verify asbestos content and work date. |
| Record | What it can show | What it cannot show alone |
|---|---|---|
| Equipment plate | Maker, model or serial number. | Asbestos content of a changed part. |
| Original parts list | Specified components at installation. | Later field substitutions. |
| Maintenance invoice | Parts ordered for a repair. | Whether a worker handled each part. |
| Material specification | Specified composition or supplier. | Which material was actually installed. |
For example, a turbine bearing a De Laval plate might have adjacent pipe insulation installed by a different contractor. A later gasket could also have come from another supplier. Examine equipment files and work orders before assigning either material to the manufacturer. This distinction makes the exposure account more precise and avoids treating all dust in a powerhouse as one company’s product.
If a manual describes a seal without specifying its composition, preserve the manual but look for a dated parts revision, purchase invoice or retained sample. Material labels may have changed over the service life of a machine. The same model designation is therefore only a lead, not proof of what was inside an individual installation.
👷 Workers and Job Sites Where Exposure May Be Investigated
Industrial plants and Navy ships appear in the court’s description of De Laval machinery. Workers who installed, repaired or worked near such equipment may have encountered suspect materials when they were disturbed. A vessel assignment or power plant job is a starting point, not proof that the worker encountered asbestos from a De Laval product.
| Worker | Possible task | Detail to record |
|---|---|---|
| Turbine mechanic | Opened casing or serviced seals. | Unit number, dates and removed part. |
| Machinist | Rebuilt pump or turbine assembly. | Model and shop work order. |
| Pipefitter | Separated steam flanges or lines. | Gasket source and work area. |
| Insulator | Removed or applied thermal covering. | Material label and contractor. |
| Shipyard worker | Worked in or near an engine room. | Vessel, compartment and assignment. |
| Setting | Useful identifier | Supporting source |
|---|---|---|
| Power station | Plant, unit and outage. | Plant maintenance logs. |
| Industrial facility | Building and equipment tag. | Process drawings and payroll. |
| Navy ship | Vessel, hull and machinery space. | Service and ship repair records. |
| Repair shop | Customer unit and rebuild number. | Shop tickets and parts orders. |
See the site’s power plant exposure guide for broader plant context. Marine assignments require their own vessel and equipment records. Coworkers may remember the location and task, while contemporaneous documents may establish dates and equipment identity.

🌫️ How De Laval-Related Asbestos Exposure Could Occur
Asbestos is most concerning when fibers become airborne and are inhaled. EPA explains that disturbance of asbestos-containing materials can release fibers. Servicing a historic steam system might involve cutting insulation, scraping a gasket or removing packing. Whether that task involved asbestos and whether it was connected to De Laval must be established for the actual job.
| Task | Potential release | Proof to seek |
|---|---|---|
| Opening turbine casing | Disturbance of covering or seals. | Outage scope and material records. |
| Scraping flange | Residue from an old gasket. | Part identification and replacement date. |
| Repacking a pump | Handling used packing. | Pump identity and packing specification. |
| Removing pipe covering | Dust around adjacent steam lines. | Insulation contractor and product source. |
| Cleaning after a repair | Contact with settled debris. | Crew activity and cleaning method. |
| Factor | Practical question |
|---|---|
| Distance | Was the person handling the material or nearby? |
| Duration | How long did each job last? |
| Frequency | Was the work repeated across outages? |
| Condition | Was the material intact or being removed? |
| Ventilation | Was the work in a confined machinery space? |
Secondhand exposure should also be evaluated through the specific dust source, transfer route and household contact. It cannot be inferred solely from a relative’s employment. Medical literature recognizes that asbestos exposure is linked to mesothelioma, lung cancer and other diseases; diagnosis, latency and exposure history require individual clinical review.
Work descriptions are more useful when they specify whether the material was cut, pulled out, brushed away or left undisturbed. Note protective measures, any visible debris and the people in the same space. Such details can help distinguish direct handling from nearby work without guessing at a dose.
⚖️ De Laval Claims and Compensation Questions
IMO’s appellate litigation involved insurers and the financial allocation of asbestos liabilities. That opinion does not create a claimant payment schedule, establish a De Laval settlement amount or determine an individual’s eligibility. No dedicated De Laval trust was confirmed in the reviewed official materials. A claimant should verify any proposed filing channel against current official trust or court documents rather than assuming that a trust exists.
| Path | What to verify | Important limit |
|---|---|---|
| Product liability action | Defendant identity, product and exposure. | Corporate history alone is insufficient. |
| Other product claim | Separate makers of replacement materials. | Do not attribute outside parts automatically. |
| Asbestos trust | Official trust, criteria and relevant product. | Do not assume a De Laval trust. |
| Employment or service benefits | Applicable program and service record. | Eligibility varies by program. |
| Question | Why it matters |
|---|---|
| Which company made the specific item? | Identifies a potentially relevant party. |
| Who sold or installed a replacement? | Distinguishes later material from original equipment. |
| Where and when was the exposure? | Connects work to records and governing law. |
| What diagnosis is documented? | Establishes a medical starting point. |
| What filing deadline applies? | Timeliness depends on case and jurisdiction. |
Compensation is never established by a company name alone. Relevant law, product identification, medical evidence and the defendant’s response affect the outcome. Keep any insurer-coverage litigation separate from a person’s exposure claim: a court deciding which insurer pays a company has not thereby decided a worker’s case.
Ask a reviewer to check the filing period promptly because deadlines depend on the jurisdiction and type of claim. Preserve records even if the original employer closed or the equipment was replaced; archived payroll, service files and supplier documents may still help reconstruct the history.
📚 Documented Records and Their Limits
The appellate opinion is unusually direct about the De Laval asbestos connection: it identifies both a historical corporate sequence and asbestos-containing components in some products made over several decades. It does not list every affected turbine model or name every exposed worker. EPA and the National Cancer Institute provide general scientific context, not company-specific proof.
| Source | Supported fact | Boundary |
|---|---|---|
| 2014 New Jersey appellate decision | Delaval history and some asbestos-containing components. | No complete inventory of affected units. |
| EPA asbestos overview | Historical uses and potential disturbance. | No De Laval site-specific identification. |
| National Cancer Institute | Asbestos health risks and latency. | No individual causation finding. |
| Proposed statement | Evidence status |
|---|---|
| De Laval produced steam machinery for naval use. | Supported by appellate opinion. |
| Some historic product components contained asbestos. | Supported by appellate opinion. |
| Every turbine had asbestos insulation. | Not established by these records. |
| A specific worker inhaled De Laval dust. | Needs individual task and material evidence. |
| There is a fixed De Laval payout. | Not established by insurance opinion. |
When reading older reports, note whether “Delaval” refers to the manufacturer, an equipment brand or a later business. A public case opinion can guide research, but a claim still calls for the actual equipment and material history at the relevant job site.
🗂️ Evidence to Gather for a De Laval Exposure Review
Start with a timeline: employer or military assignment, facility or vessel, unit, tasks, coworkers and dates. Next connect the suspected material to a product specification or supply record. Keep the original wording of documents, especially where “Delaval,” “De Laval” or “IMO” appears; changing names in transcriptions can obscure a useful match.
| Document | What it may establish |
|---|---|
| Employment or service record | Dates, location, role and unit. |
| Equipment list or plate photo | Manufacturer and model. |
| Outage or ship repair order | Task, machinery and work period. |
| Parts catalog and invoices | Original or replacement material supplier. |
| Coworker account | How work occurred and who was nearby. |
| Pathology and clinical records | Diagnosis and medical history. |
| Check | Why it helps |
|---|---|
| Match dates | Parts can change over decades. |
| Match unit identifiers | A large plant may have several makers’ machines. |
| Separate insulation from machine parts | Supply and installation may involve other companies. |
| Keep full document pages | Context can qualify a short excerpt. |
| Verify current filing rules | Procedures and deadlines may differ. |
A family member gathering records after a death may also need documents establishing authority to act. For marine work, identify the vessel and compartment; for stationary plants, identify the unit and outage. The site’s power and electrical companies category and marine transportation category can help organize leads to other companies, without substituting for proof about De Laval.
❓ Frequently Asked Questions
Did De Laval make asbestos-containing products?
The New Jersey appellate opinion says some components in products made from the 1940s through the 1980s contained asbestos. Identify the relevant product and period before drawing conclusions about one job.
Were all De Laval steam turbines insulated with asbestos?
The reviewed court record does not establish that. Insulation could vary by model, location, installation and later maintenance.
Is Delaval the same spelling as De Laval?
The court uses “Delaval Steam Turbine Company.” Both spellings may be useful in a historical search; confirm the exact entity named in each record.
Does a De Laval nameplate prove exposure?
No. It identifies equipment, while exposure requires evidence of an asbestos-containing material, disturbance, proximity and timing.
Could Navy engine-room work be relevant?
Yes. The court describes equipment used on Navy ships. Identify the vessel, machinery, compartment and repair activity to investigate a specific history.
Is there a De Laval asbestos trust?
No dedicated De Laval trust was confirmed in the official materials reviewed for this page. Verify any suggested trust against its current governing documents and product criteria.
