Hubbard High School: Facility Background and Asbestos Exposure Risk

Facility Overview

Rosco L. Hubbard High School is a Chicago Public Schools facility located at 6200 South Hamlin Avenue in the Auburn Gresham neighborhood on Chicago’s South Side. The school opened in 1928—an era when asbestos-containing materials were the industry standard in large institutional construction.

Original construction and subsequent renovations through the 1980s reportedly incorporated asbestos-containing materials throughout the building:

Steam heating systems with asbestos-insulated pipes and boilers
Spray-applied fireproofing on structural steel
Pipe insulation, block insulation, and duct insulation throughout mechanical systems
Floor tiles, ceiling tiles, and acoustic insulation in classrooms and hallways
Electrical components and switchgear with asbestos-containing insulation
Roofing materials and asbestos-cement products

Chicago Public Schools faced mandatory inspection and abatement requirements under federal law. Workers may have been exposed to asbestos fibers for decades before any remediation occurred.

Why Asbestos Was Used — and Why Workers Were Not Warned

Properties That Made Asbestos Standard in Construction

Builders and manufacturers used asbestos because it delivered measurable performance advantages:

Withstands temperatures exceeding 2,000°F without degradation
Fibers stronger than steel wire of comparable diameter
Resists acids, alkalis, and corrosive substances
Non-conductive—suitable for electrical applications
Absorbs sound in large buildings
Low cost and readily available throughout the 20th century

What Manufacturers Knew — and Concealed

Major asbestos manufacturers—including Johns-Manville, Owens-Illinois, Owens Corning, W.R. Grace, Eagle-Picher, Garlock Sealing Technologies, Armstrong World Industries, Georgia-Pacific, Celotex, Crane Co., and Combustion Engineering—possessed internal knowledge of asbestos health hazards decades before workers or the public received any warning. Litigation documents establish that these manufacturers suppressed, distorted, and concealed evidence of asbestos-related disease risks from workers, customers, and government regulators.

The regulatory timeline tells the story plainly:

Before 1971: No enforceable OSHA exposure limits for asbestos
1971–1975: Weak standards with inadequate enforcement
1976–1985: Standards tightened gradually; widespread non-compliance continued
1986 onward: AHERA enacted, requiring school asbestos inspections and management plans

Workers at Hubbard High School may have handled asbestos-containing materials for 30 or more years with no respiratory protection, no hazard training, and no warning of documented health risks. The manufacturers knew. The workers did not.

Timeline of Reported Asbestos-Containing Material Use at Hubbard High School

Original Construction Era (Late 1920s–1940s)

During original construction and the decades that followed, mechanical and structural systems allegedly incorporated asbestos-containing materials as standard practice:

Pipe insulation on steam lines and hot water systems
Boiler insulation and insulating block
Spray-applied fireproofing on structural steel columns and beams
Electrical insulation on wiring and components
Gaskets and packing materials in pipes and valves

Mid-Century Renovation and Expansion (1950s–1970s)

Significant renovation work reportedly introduced asbestos-containing products from Johns-Manville, Owens-Illinois, W.R. Grace, Celotex, and Armstrong World Industries, while simultaneously disturbing legacy asbestos-containing materials already in place:

Floor tiles and vinyl asbestos tile (VAT)
Suspended ceiling tiles and acoustic insulation
Duct insulation on HVAC systems
Replacement pipe insulation products such as Kaylo and Thermobestos
Roofing and roofing felts
Joint compounds and spackling allegedly containing asbestos (Gold Bond and Sheetrock)

Ongoing Maintenance and Repair Work (1960s–1980s)

Routine maintenance throughout this period reportedly disturbed existing asbestos-containing materials on a recurring basis:

Boiler maintenance and repair—daily or weekly
Pipe repairs and valve replacement
Electrical upgrades and rewiring
Floor and ceiling repairs
Insulation patching and replacement

Every repair cycle was a potential exposure event. Workers performing these tasks typically received no hazard warnings and no respiratory protection.

AHERA-Required Inspections and Abatement (1986–Present)

Federal law required Chicago Public Schools to inspect and manage asbestos-containing materials under AHERA:

Mandatory building inspections and asbestos surveys
Development of asbestos management plans
Abatement and encapsulation activities—which themselves create exposure risk when performed without proper engineering controls

Occupational Groups with Highest Asbestos Exposure Risk

Exposure at Hubbard High School was not limited to workers who directly handled asbestos-containing materials. Fiber release from one trade’s work exposed workers in adjacent areas. Years of repeated short exposures accumulated into significant cumulative dose.

Three exposure categories matter in litigation:

Direct exposure: Workers cutting, fitting, or installing asbestos-containing materials
Bystander exposure: Workers in adjacent areas inhaling fibers released by others’ work
Cumulative exposure: Multiple short exposures over years or decades of employment

Maintenance Workers and Custodians

Maintenance workers and custodians logged daily time in mechanical rooms, boiler rooms, and pipe chases where asbestos-containing materials were reportedly present. They performed routine tasks that may have disturbed those materials—tightening fittings, replacing gaskets, patching insulation. A worker who spent 20 or 30 years in the same building may have accumulated exposure that only now produces disease. Most received no formal training and no respiratory protection.

Boilermakers and Stationary Engineers

Steam heating systems in large institutional buildings were typically insulated with asbestos-containing block insulation. Steam pipes throughout the building may have been wrapped with asbestos-containing pipe covering. Repair and maintenance required removing, cutting, and replacing that insulation—generating airborne fiber concentrations that building ventilation did not clear. Workers in boiler rooms faced repeated, prolonged exposure over entire careers.

Pipefitters and Plumbers

These trades may have directly handled asbestos-containing materials as a routine part of the job:

Cutting and fitting asbestos-containing pipe insulation products such as Kaylo and Thermobestos
Installing and removing asbestos-containing rope packing and gaskets allegedly manufactured by Johns-Manville and Garlock Sealing Technologies
Working with asbestos-containing valve stem packing requiring manual handling
Pipe repair, replacement, and system modifications throughout the building

Electricians

Electricians may have encountered asbestos-containing materials from multiple sources:

Electrical wiring insulation reportedly incorporating asbestos near heat sources
Work in close proximity to pipe insulation and structural fireproofing
Drilling through walls, ceilings, and floor assemblies containing asbestos-containing materials
Arc chutes, insulating panels, and switchgear components reportedly containing asbestos
Disassembly and repair of asbestos-containing electrical equipment

Insulators

Members of the International Association of Heat and Frost Insulators and Allied Workers represent one of the highest-risk occupational groups for asbestos-related disease in any industry. Their work required direct application and removal of asbestos-containing pipe insulation products—including Kaylo, Thermobestos, and products from Johns-Manville and Owens-Illinois—along with block insulation, boiler insulation, and duct insulation. Mesothelioma rates among insulators are among the highest documented in any occupational cohort.

Carpenters

Carpenters working at Hubbard High School may have encountered asbestos-containing building materials throughout renovation and maintenance work:

Cutting and fitting vinyl asbestos floor tiles
Removing and installing asbestos-containing ceiling tiles
Sanding, cutting, and drilling drywall and joint compounds allegedly containing asbestos (Gold Bond, Sheetrock)
Cutting and drilling operations that generate high airborne fiber concentrations

Painters

Painters may have encountered asbestos-containing materials in surface finishes and compounds:

Asbestos-containing textured paints on walls and ceilings
Asbestos-containing drywall joint compounds and spackling
Surface preparation—particularly sanding—generating asbestos dust
Spray application of asbestos-containing coatings

Teachers, Administrative Staff, and Students

Occupational exposure risk for non-trades workers is generally lower than for skilled trades. That said, these groups may have had legitimate exposure concerns:

Extended time in aging buildings with deteriorating asbestos-containing materials
Indoor air quality problems if asbestos-containing materials were damaged or disturbed
Potential exposure from inadequately controlled abatement work
Compromised asbestos-containing materials in older classrooms and common areas that were not properly managed

Asbestos-Containing Products Allegedly Present at Hubbard High School

Based on the building’s construction history and documented use of asbestos-containing products in Chicago Public Schools facilities of that era, the following materials are alleged to have been present:

Insulation Products

Pipe insulation (“85% magnesia,” “pipe wrap”) from Johns-Manville and Owens-Illinois—typically applied to steam and hot water pipes throughout the building’s mechanical systems
Block insulation from Johns-Manville and W.R. Grace—sectional insulation for boilers and large pipes, held in place with wire or banding
Boiler insulation including Kaylo and Thermobestos from Eagle-Picher and Johns-Manville—pre-formed asbestos-containing insulation on steam boilers
Duct insulation from multiple manufacturers—asbestos-containing insulation on HVAC ductwork
Equipment insulation from Crane Co. and others—covering pumps, valves, compressors, and mechanical equipment

Fireproofing and Structural Materials

Spray-applied fireproofing from W.R. Grace, Johns-Manville, and Combustion Engineering—applied to structural steel be
