Office Building Workers Asbestos Exposure

Office Building Workers and Asbestos Exposure

Office buildings can contain asbestos-containing materials that remain in place for decades. EPA explains that an operations and maintenance program may be appropriate for office buildings, shopping centers, apartment buildings, hospitals and similar facilities containing asbestos materials that can be safely managed in place.

The presence of asbestos-containing material does not automatically establish that an office employee inhaled asbestos. EPA’s management approach focuses on keeping material in good condition, monitoring it and preventing disturbance or fiber release.

Exposure concern becomes more specific when material deteriorates, is damaged by leaks or building work, or is disturbed during maintenance, repair, renovation or demolition.

NIOSH’s evaluation of the Fallon Federal Office Building illustrates this distinction. Investigators identified asbestos-containing fireproofing and warned that deterioration or disturbance during renovation or maintenance could potentially result in hazardous asbestos exposure to office workers.

Related resources include public sector, government and institutional workers asbestos exposure, asbestos exposure in buildings, maintenance workers asbestos exposure and building inspectors asbestos exposure.

Asbestos-Containing Materials in Office Buildings

OSHA defines asbestos-containing material as material containing more than 1% asbestos. For purposes of its general-industry asbestos standard, certain thermal-system insulation and sprayed-on or troweled-on surfacing materials in buildings constructed no later than 1980 are treated as presumed asbestos-containing material unless the presumption is properly rebutted.

EPA’s building-management guidance groups asbestos-containing materials into categories that include surfacing material and thermal-system insulation.

Materials and Locations Worth Investigating

• Documented asbestos-containing sprayed or troweled fireproofing
• Acoustical or decorative surfacing material confirmed to contain asbestos
• Asbestos-containing insulation on pipes, boilers, tanks or ducts
• Flooring and associated materials identified as asbestos-containing
• Mechanical-room materials documented as asbestos-containing
• Other office-building materials confirmed by survey, sampling or reliable records

OSHA requires building and facility owners in covered workplaces to determine the presence, location and quantity of asbestos-containing material and presumed asbestos-containing material and retain relevant records during ownership.

A building’s age can help identify which records deserve review, but age alone does not establish that a particular material contained asbestos or that an employee was exposed.

Maintenance, Renovation and Fiber Release

Maintenance and renovation can change the condition of asbestos-containing material. EPA states that its asbestos NESHAP work-practice requirements apply to covered demolitions and renovations of structures, installations and buildings.

Office-worker exposure questions can arise when asbestos-containing materials are disturbed in or near occupied areas.

Activities Worth Investigating

• Ceiling or wall work disturbing confirmed asbestos surfacing material
• Repair of pipes, boilers, ducts or other systems with asbestos insulation
• Removal of asbestos-containing flooring or other building materials
• Renovation performed next to occupied offices
• Water damage affecting asbestos-containing fireproofing or insulation
• Fiber-release episodes followed by cleanup or reoccupation
• Demolition or major remodeling involving documented asbestos materials

NIOSH’s Fallon Building evaluation recommended contaminant barriers, worker protection, wetting agents, proper cleanup, waste disposal and air monitoring when renovation or maintenance disturbed asbestos-containing fireproofing.

Related occupation resources include maintenance mechanics asbestos exposure, demolition workers asbestos exposure and electricians, plumbers and HVAC technicians at risk.

Office Occupants, Custodians and Building Staff

Office occupants, custodians and maintenance employees can have very different exposure histories even when they work in the same building.

OSHA specifically states that housekeeping employees in public and commercial buildings with installed asbestos-containing materials may be exposed to asbestos fibers. Building owners and employers must inform employees performing housekeeping activities in areas containing asbestos-containing or presumed asbestos-containing material about its presence and location.

OSHA also requires asbestos-awareness training for employees who perform housekeeping operations in areas containing such material. The training covers asbestos health effects, locations of asbestos-containing material, recognition of damage and deterioration, housekeeping requirements and response to fiber-release episodes.

For ordinary office employees, the strongest evidence generally involves documented deterioration, airborne or surface contamination, renovation activity or a fiber-release episode affecting the occupied work area.

NIOSH’s Federal Office Building evaluation in Evansville, Indiana, found chrysotile asbestos in sprayed-on fireproofing and asbestos in settled-dust samples. Investigators concluded that a potential health hazard existed because of deteriorating and water-damaged fireproofing and recommended removal, operations-and-maintenance procedures, surveillance, medical monitoring and employee education.

Building Records, Monitoring and O&M Programs

Office-building asbestos investigations can benefit from records created by building owners, employers, industrial hygienists and contractors.

EPA describes an asbestos operations and maintenance program as a plan involving training, cleaning, work practices and surveillance designed to maintain asbestos-containing materials in good condition and minimize exposure of building occupants to asbestos fibers.

Records Worth Requesting

• Asbestos surveys and bulk-sample laboratory reports
• Operations and maintenance plans
• Records identifying the location and quantity of asbestos-containing material
• Periodic surveillance and condition assessments
• Air-monitoring and surface-sampling results
• Water-damage and repair records
• Renovation, abatement and demolition files
• Fiber-release incident and cleanup records
• Employee notices, warning signs and asbestos-awareness training records

OSHA requires covered building owners to maintain information concerning the presence, location and quantity of asbestos-containing and presumed asbestos-containing material for the duration of ownership and transfer those records to successive owners.

Historical NIOSH office-building investigations show how air samples, settled-dust samples, bulk samples and visual inspection can be combined to evaluate whether deteriorating asbestos-containing material may affect occupied areas.

Mesothelioma and Other Asbestos-Related Health Risks

NIOSH’s scientific review recognizes occupational asbestos exposure as a carcinogenic hazard. Diseases associated with asbestos exposure include malignant mesothelioma, lung cancer and asbestosis.

Office buildings can also have respiratory hazards unrelated to asbestos. NIOSH, for example, has documented health effects associated with dampness and mold in office buildings, schools and other nonindustrial buildings. Mold, dampness and asbestos are distinct hazards and should not be conflated.

Asbestos-related disease can develop after a long latency period. Former office employees may therefore need decades-old building records, employment documents, renovation files and coworker accounts to reconstruct a potential historical exposure.

Working in a building containing asbestos does not by itself establish disease causation. Exposure opportunity, dose-related circumstances, medical evidence and other relevant factors must be evaluated individually.

Medical questions about prior occupational asbestos exposure, symptoms, screening or diagnosis should be discussed with a qualified healthcare professional.

Documenting Office Building Asbestos Exposure

A useful office-worker exposure history combines employment evidence with building-specific asbestos documentation.

• Employment: employer, agency, dates, job title and department
• Location: building, floor, office, workstation and regularly used common areas
• Building evidence: asbestos surveys, O&M plans, sampling and inspection records
• Material evidence: type, location and condition of asbestos-containing material
• Disturbance: renovation, maintenance, water damage, abatement or demolition
• Environmental evidence: air samples, surface samples and fiber-release records
• Communications: employee notices, warning signs, emails and safety reports
• Witnesses: coworkers, custodians, maintenance staff, building managers and contractors

Questions That Can Strengthen an Exposure History

Which building and years? Which floor and office? Was asbestos-containing material documented nearby? Was it damaged or deteriorating? Did renovation, maintenance or water damage occur? Were employees notified? Are surveys, monitoring results, photographs, work orders or coworkers available?

Lawsuits, Trust Funds and Compensation

An office building worker diagnosed with mesothelioma or another asbestos-related disease may have potential legal or compensation options when evidence supports occupational asbestos exposure and applicable requirements are met.

Office employment alone does not establish asbestos exposure, causation, liability, trust eligibility or compensation. Depending on the evidence and jurisdiction, potential issues can involve asbestos-product companies, contractors, premises-related parties, workers’ compensation systems or asbestos bankruptcy trusts.

Government office employees may also be subject to jurisdiction-specific procedural rules or deadlines. Compensation is not guaranteed.

Office Building Workers Asbestos Exposure FAQ

Were all office building workers exposed to asbestos?

No. Office employment does not establish asbestos exposure. The building, material, condition, disturbance, work location and time period should be documented.

Can an office building contain asbestos without exposing workers?

Yes. EPA provides guidance for safely managing asbestos-containing material in place when it remains in good condition. Exposure concern increases when material deteriorates or is disturbed.

What asbestos materials may be found in office buildings?

Depending on the building, documented materials can include surfacing or fireproofing material, thermal-system insulation and flooring or other building products confirmed to contain asbestos.

Can renovation increase asbestos exposure concerns?

Potentially. Renovation, repair or demolition can disturb asbestos-containing materials and release fibers if appropriate controls are not used.

Are custodial workers treated differently from ordinary office occupants?

OSHA specifically addresses housekeeping employees working in areas containing asbestos-containing or presumed asbestos-containing material and requires information and asbestos-awareness training in covered situations.

What is an asbestos operations and maintenance program?

EPA describes it as a plan using training, cleaning, work practices and surveillance to keep asbestos-containing materials in good condition and minimize exposure of building occupants.

What records can help document office-building asbestos exposure?

Asbestos surveys, O&M plans, bulk and air sampling, renovation records, water-damage files, employee notices, incident reports, photographs and coworker statements can help reconstruct exposure.

Can office workers qualify for asbestos trust fund claims?

Some may qualify if they meet a trust’s medical and exposure requirements and can connect their exposure to a covered asbestos company, product, site or qualifying period. Office employment alone does not establish eligibility.
