Tank Products Asbestos Exposure

Tank Products and Historical Asbestos Use

Industrial tanks can store, mix, process or heat liquids, chemicals, fuels and other materials. Some tanks operate at elevated temperatures or connect to steam, hot-water, pumping or process systems that require insulation and heat-resistant sealing products.

Historically, some asbestos-containing products were used around tanks for thermal insulation, fire protection and sealing. Potentially relevant materials could be installed on the tank exterior, around manways and flanges, on steam jackets, on connected piping, around valves and pumps, or inside nearby electrical and control equipment.

The presence of an older tank does not prove asbestos exposure. The exact tank type, manufacturer, process, attached equipment, facility, service period and maintenance history should be evaluated whenever possible.

Tank-System Materials That May Have Involved Asbestos

Depending on manufacturer, application and year, historical asbestos-containing tank-system materials may have included:

• thermal insulation on tank exteriors;
• insulation on steam jackets or heating coils;
• pipe insulation on connected steam, hot-water or process lines;
• flange and manway gaskets;
• valve and pump packing;
• heat-resistant rope and sealing materials;
• insulating cement around fittings or irregular surfaces;
• heat-resistant tape or cloth wrapping;
• insulating boards or heat shields near hot equipment;
• electrical insulation in nearby controls or motors;
• fireproofing around tank and process areas; and
• other specialty materials selected for heat or fire resistance.

Each material should be evaluated separately because a tank system can include many products with different asbestos histories.

How Asbestos Exposure Could Occur

A potential exposure pathway requires asbestos-containing material and work that disturbs it. Intact insulation or gaskets may present a different exposure potential than materials that are deteriorated, cut, scraped or removed.

Potential disturbance could occur during tasks such as:

• removing tank or steam-jacket insulation;
• cutting insulation from connected piping;
• replacing manway or flange gaskets;
• scraping old gasket residue from metal surfaces;
• removing valve or pump packing;
• repairing insulated heating coils or jackets;
• cutting heat-resistant rope, tape or cloth;
• servicing nearby motors, controls or electrical equipment;
• removing obsolete tanks or process systems; and
• cleaning debris after insulation or gasket work.

Actual exposure depends on asbestos content, material condition, disturbance method, frequency, duration, proximity, ventilation and controls.

Workers and Job Sites That May Have Encountered Tank Systems

Workers who installed, operated, maintained, insulated, repaired or removed historical tank systems may have encountered asbestos-containing products if those materials were present and disturbed. A job title alone does not establish exposure.

Potentially relevant occupations may include maintenance mechanics, millwrights, pipefitters, plumbers, insulators, boilermakers, refinery workers, chemical-plant workers, electricians and demolition workers.

Possible settings include refineries, chemical plants, factories, power plants, food-processing facilities, shipyards, military installations, utility facilities and other industrial sites using storage or process tanks.

Nearby workers may also be relevant when insulation removal, gasket scraping or piping repairs generated dust in shared work areas.

Tank Maintenance, Repair and Removal Risks

Tank insulation work

Some process or heated tanks were insulated to control temperature. If the insulation contained asbestos, cutting or stripping it could release fibers.

Gasket replacement

Manways, flanges, heating connections and process piping may use heat-resistant gaskets. Some historical gaskets contained asbestos, and scraping hardened residue can disturb fibers.

Valve and pump packing

Connected valves and pumps may use packing to control leakage. Removing asbestos-containing packing could generate dust when present.

Steam jackets and heating systems

Tanks that used steam or hot-water jackets may have asbestos-containing insulation on the jacket, piping, valves or fittings even when the tank shell itself was not asbestos-containing.

Tank removal and demolition

Removing an obsolete tank can disturb insulation, gaskets, packing, pipe covering, fireproofing and nearby building materials at the same time. Each possible source should be identified separately.

Evidence That May Identify Asbestos-Containing Tank Materials

Exposure reconstruction is strongest when evidence identifies the exact tank, attached equipment or applied material, manufacturer, facility, service period and work performed.

Useful evidence may include:

• tank manufacturer, model and serial numbers;
• equipment nameplates and vessel records;
• engineering drawings and piping diagrams;
• insulation and process specifications;
• gasket and packing part numbers;
• parts catalogs and maintenance manuals;
• purchase orders, invoices and supplier records;
• maintenance logs and work orders;
• tank inspection and repair records;
• facility equipment inventories;
• historic photographs of tanks and process areas;
• asbestos surveys and abatement records;
• laboratory reports for surviving insulation, gaskets, packing, rope or cloth;
• employer, union or military records documenting assignments; and
• coworker or supervisor statements identifying materials and tasks.

Testing and documentation should distinguish tank insulation, pipe insulation, gaskets, packing, rope, tape, fireproofing and nearby building materials whenever those products can be separately identified.

Medical and pathology records may document an asbestos-related diagnosis but do not establish which historical tank-system material was an exposure source.

Secondhand Exposure and Health Risks

If work with asbestos-containing tank materials generated fibers that accumulated on clothing, shoes, tools or belongings, asbestos could potentially have been carried away from the job site. This is a possible secondhand exposure pathway, but family relationship alone does not establish exposure.

Asbestos exposure is associated with mesothelioma, asbestos-related lung cancer, asbestosis and other asbestos-related disease. Working around older tank systems does not diagnose disease and does not establish individual medical causation.

Anyone concerned about historical occupational asbestos exposure should discuss their work history and health with a qualified healthcare professional.

Legal and Compensation Considerations

Depending on the evidence and circumstances, legal options may be available to a person diagnosed with an asbestos-related disease after documented exposure to a specific asbestos-containing tank-system product or component.

A legal review may consider the tank and component manufacturers, product suppliers, facility or job site, service period, tasks performed, frequency and duration of exposure, diagnosis, jurisdiction and filing deadlines.

Identifying a tank manufacturer, insulation supplier, contractor or facility owner does not automatically establish legal responsibility. Liability is case-specific and depends on product evidence, exposure evidence and governing law.

Some matters may involve asbestos trust funds, but each trust has its own product, exposure and medical documentation requirements. Eligibility is not automatic, and compensation is not guaranteed.

Exposure that occurred decades ago does not by itself determine whether a claim is timely. Statutes of limitation and other deadlines vary by jurisdiction and circumstances and should be reviewed individually.
