About Firrium Desloge Hospital

Firmin Desloge Hospital, part of the SSM Health Saint Louis University Hospital system, was built and expanded during decades when asbestos-containing materials were the industry standard for fireproofing, thermal insulation, and building construction. Skilled tradesmen who kept this large urban hospital running worked daily in its mechanical spaces. That work may have meant repeated, sustained exposure to airborne asbestos fibers — exposure now alleged to be linked to mesothelioma, lung cancer, and asbestosis.

Large Missouri hospitals of the mid-twentieth century were not simply medical buildings — they were small industrial complexes. They required central steam plants, miles of insulated piping running through pipe chases and ceiling plenums, and a constant workforce of skilled tradesmen performing installation, repair, and renovation work. At a facility of Firmin Desloge Hospital’s scale and age, that work allegedly brought tradesmen into close, repeated contact with asbestos-containing insulation, fireproofing, and building materials.

Hospitals like Firmin Desloge depended on high-pressure steam generated in large central boiler plants to heat the facility, sterilize surgical equipment, and power laundry operations. Boilers manufactured by, and were commonly insulated with asbestos-containing materials designed to withstand temperatures regularly exceeding 400 degrees Fahrenheit. From the central boiler plant, steam traveled through an extensive network of pipes running through basement corridors, pipe tunnels, mechanical rooms, and vertical pipe chases. These pipes were wrapped in pre-formed asbestos pipe covering. HVAC systems installed during this era reportedly incorporated asbestos-containing duct insulation lining air handling equipment and return plenums, flexible asbestos fabric connectors joining ductwork sections, and Transite board (calcium silicate and asbestos-cement panels) used to construct air handling equipment housings and pipe chase enclosures.

General Equipment at Firrium Desloge Hospital

The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.

Documented Asbestos Evidence

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri DNR) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

No Missouri DNR NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at Firrium Desloge Hospital

Workers in the following trades are alleged to have experienced the highest levels of asbestos exposure at hospital facilities like Firmin Desloge Hospital:

Boilermakers worked directly with boiler shells, fireboxes, and high-temperature fittings surrounded by asbestos insulation, cutting, fitting, and replacing asbestos block and blanket insulation on equipment, and handling gaskets and packing materials during assembly and maintenance.

Pipefitters and Steamfitters, members of Plumbers and Pipefitters UA Local 562 (St. Louis) and UA Local 268 (Kansas City), are alleged to have worked extensively with asbestos-insulated steam systems at Missouri hospital facilities. They cut, fitted, and replaced pre-formed asbestos pipe covering throughout the steam distribution system, measured and fitted asbestos insulation sections in confined pipe chases and mechanical rooms, and removed old spray-applied fireproofing and pre-formed pipe insulation during pipe replacement and renovation work.

Heat and Frost Insulators, members of Heat and Frost Insulators Local 1 (St. Louis) and Local 27 (Kansas City), had primary job functions involving applying, repairing, and removing asbestos-containing insulation products. They worked directly with asbestos-containing insulation in boiler rooms, pipe tunnels, and mechanical equipment spaces with sustained, direct contact with friable asbestos materials, and removed and replaced transite board pipe chase enclosures.

HVAC Mechanics worked in plenum spaces and mechanical rooms where asbestos duct insulation and transite board were allegedly present, installing, modifying, and removing asbestos-containing ductwork components and spray-applied fireproofing around air handling units, and replacing aging equipment surrounded by asbestos insulation.

Electricians ran conduit through pipe chases and ceiling spaces where asbestos insulation may have been disturbed overhead, worked in confined mechanical rooms where asbestos dust from aged spray-applied fireproofing and transite board allegedly accumulated on surfaces and in the air, and installed electrical systems in newly constructed or renovated areas containing asbestos materials.

Maintenance Workers and Stationary Engineers performed daily rounds and repairs in boiler rooms and mechanical spaces containing asbestos-insulated equipment, responded to steam leaks in systems wrapped with asbestos pipe insulation, and sustained chronic, low-level exposure over years or decades in spaces where spray-applied fireproofing-coated structural steel and transite enclosures had aged and crumbled.

⚠️ Critical Filing Deadline

Missouri law gives mesothelioma and asbestos-disease victims 5 years from the date of medical diagnosis to file a personal injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). Miss either deadline by a single day and the right to file is permanently gone. No exceptions, no extensions.

About the two deadlines: Missouri keeps the personal-injury clock (Mo. Rev. Stat. § 516.120) and the wrongful-death clock (Mo. Rev. Stat. § 537.100) on separate tracks. The 5 years personal-injury deadline runs from the date of diagnosis and applies to the diagnosed person's own claim while they are alive. The 3 years wrongful-death deadline runs from the date of death and applies to surviving family members. The two are independent — preserving one does not extend the other, and an asbestos attorney with experience in Missouri can keep both options open as the situation evolves.

The personal-injury clock runs from the date of medical diagnosis — not from the date of asbestos exposure. Mesothelioma can take 20 to 50 years to develop after exposure. Many workers are only now receiving diagnoses from exposures that occurred decades ago.

Treat the 5 years deadline as a hard outer limit, not a planning horizon.

⚠️ Why You Must Act Now

Missouri's filing window may sound like ample time. It is not. Every month that passes after a mesothelioma diagnosis is a month in which your case gets harder to build and your options narrow.

Witnesses Become Harder to Reach

The tradespeople who worked alongside mesothelioma victims at facilities of this era are now in their 70s and 80s. Witnesses from many years ago are harder and harder to contact by the day — coworkers who can testify about which asbestos-containing materials were used, who supplied them, and how the work was done are increasingly difficult to locate. Once first-hand testimony becomes unavailable, that record is gone.

Records Disappear

Employment records, union records, purchasing records, and product invoices that document exactly which asbestos-containing materials were used at this facility are being lost every year. Plants close. Corporate owners change. Storage facilities are cleared. Records that existed five years ago may not exist today.

Mesothelioma Cases Are Complex to Build

Identifying every responsible manufacturer and every jobsite across a tradesperson's career requires intensive investigation by experienced toxic-tort counsel. A case against the manufacturers who supplied asbestos-containing materials to this facility may involve dozens of defendants. That investigation takes time that waiting families do not have.

Asbestos Trust Fund Claims Run on a Separate Track

More than 60 asbestos bankruptcy trusts exist to compensate victims whose exposures came from manufacturers that have since gone bankrupt — including the Manville Personal Injury Settlement Trust, established after the 1982 Johns-Manville bankruptcy. Each trust has its own claim forms, exposure criteria, documentation requirements, and processing timelines. Pursuing trust-fund compensation in parallel with a lawsuit takes months. The trust-fund process should start now, not after you decide whether to file suit.

What To Do Next

If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease — and you worked at this facility, lived with someone who did, or worked at neighboring industrial sites in the corridor — the practical next steps are:

  1. Speak with an asbestos attorney with experience in Missouri. The first conversation is free, confidential, and creates no obligation. An experienced attorney will help you understand which trust-fund claims may apply, which civil claims are viable, and what documentation you should start gathering.
  2. Gather what you can about your work history. Pay stubs, W-2s, union cards, photographs, names of coworkers, and dates of employment all become important evidence. The WorkChain widget on this page can help you organize and email yourself a copy of your facility list.
  3. Preserve your medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests all become part of the legal record. Ask your treating physicians for full copies of everything in your chart.
  4. Identify household members who may also have been exposed. Spouses who laundered work clothing and children who hugged a parent returning from the plant are eligible for secondary-exposure claims when they have been diagnosed with an asbestos-related disease.
  5. Act before the filing deadline runs. Missouri's statute of limitations is a hard outer limit. Even if you are still in the middle of treatment decisions, beginning the legal process early preserves your options.

Asbestos-Related Diseases

Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.

Mesothelioma

A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.

Asbestosis

A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.

Lung Cancer

Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.

Other Recognized Diseases

Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.

If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
