ACM: Asbestos-containing material, any material with >1% asbestos;TSI: Thermal system insulation, ACM applied to pipes, fittings, boilers, ducts, etc. to prevent heat loss/gain; PACM: Presumed asbestos-containing material,TSI and surfacing material in buildings built ≤1980, treated as ACM until proven otherwise; PLM: Polarized light microscopy, microscopy technique to identify asbestos fibers; TEM: Transmission electron microscopy, high-resolution imaging method Thermal System Insulation (TSI) Understanding Asbestos and Thermal System Insulation What Is Asbestos-Containing Thermal System Insulation (TSI), and Where Is It Commonly Found in Buildings? UNDERSTANDING ASBESTOS AND THERMAL SYSTEM INSULATION How Can You Identify Asbestos-Containing Pipe Insulation in Commercial, Industrial, and Residential Buildings? Thermal system insulation is particularly important because many historical insulation products contain asbestos and some can release microscopic fibers when damaged or disturbed. Pipe insulation may deteriorate over time because of moisture, vibration, mechanical damage, maintenance activities, and aging. Fibers may become airborne when workers cut, drill, scrape, remove, or improperly repair asbestos-containing insulation. This creates potential exposure concerns for maintenance personnel, plumbers, HVAC technicians, construction workers, building occupants, and contractors. The risk depends on the material's asbestos content, condition, accessibility, and the activities being performed around it. Proper inspection, material identification, maintenance planning, and professional asbestos management help prevent unnecessary exposure. What Is the Difference Between Thermal System Insulation (TSI), Surfacing Materials, and Other Asbestos-Containing Building Materials? Several types of asbestos were used historically in insulation and other industrial products. The three commonly discussed commercial asbestos types are chrysotile, amosite, and crocidolite. Chrysotile is commonly called white asbestos . Amosite is commonly called brown asbestos. Crocidolite is commonly called blue asbestos . Chrysotile was widely used in numerous building and mechanical insulation products. Amosite and other amphibole asbestos types were also used in certain historical insulation applications. Crocidolite Is widely used in industrial applications due to its tensile strength and heat resistance. Typically found in insulation products, fireproof textiles, cement blends, spray-on coatings, plastics, pipe insulation, cigarette [Micronite] filters, brake liners, furnace and oven liners, and more. It's use has declined as result of Crocidolite's carcinogenic properties. The specific asbestos type cannot reliably be determined by looking at the material. Laboratory analysis by an appropriately qualified laboratory is necessary to identify asbestos and, when required, characterize the asbestos mineral type. Asbestos Identification, Inspection, and Testing Presumed Asbestos-Containing Material, or PACM, is a regulatory designation used under OSHA's asbestos construction standard. OSHA defines PACM as thermal system insulation and surfacing material found in buildings constructed no later than 1980. This means certain older pipe insulation, boiler insulation, and surfacing materials must be treated as presumed asbestos-containing materials unless the presumption is properly rebutted under applicable OSHA requirements. The designation is particularly important for contractors, employers, building owners, and maintenance personnel planning work that could disturb historical insulation. A building's construction date alone does not prove that every insulation product contains asbestos. However, the PACM designation establishes important workplace obligations. Qualified inspection, appropriate testing, and proper documentation can help determine the material's status . Asbestos Exposure, Safety, and Risk Management Is Asbestos-Containing Thermal System Insulation Dangerous If It Is Intact and Undisturbed? Intact, properly maintained asbestos-containing thermal system insulation generally presents a lower risk of fiber release than insulation that is damaged, deteriorating, or disturbed. Asbestos exposure occurs when microscopic fibers become airborne and are inhaled. However, intact material is not automatically harmless. Its condition, location, accessibility, and likelihood of future disturbance must be considered. If asbestos-containing insulation is in good condition and unlikely to be disturbed, professional management may be preferable to unnecessary removal. Building owners should maintain appropriate records, monitor material condition, and communicate relevant asbestos information to contractors and maintenance personnel. Any planned work that could disturb the insulation should be evaluated before work begins. USENVI expert takeaway: Asbestos management is not simply a decision to remove or leave material. It requires an informed evaluation of condition, exposure potential, and future building activities. Can Asbestos Fibers Become Airborne When Old Pipe Insulation Is Damaged or Disturbed? Yes. Asbestos fibers can become airborne when asbestos-containing pipe insulation is damaged, deteriorates, or is disturbed. Potential fiber-release activities include: Cutting or drilling. Scraping or sanding. Breaking or crushing. Mechanical demolition. Improper insulation removal. Certain maintenance and repair activities. Asbestos fibers are microscopic and cannot be reliably identified by looking at dust or debris. Air monitoring, when appropriate, must be conducted using recognized sampling and analytical procedures by qualified professionals. The presence of visible dust does not establish an asbestos concentration, and the absence of visible dust does not prove that airborne asbestos is absent. USENVI expert takeaway: Suspected asbestos insulation should be evaluated before disturbance, and potential exposure should be addressed through appropriate professional controls and assessment. What Should Contractors, Plumbers, HVAC Technicians, and Maintenance Workers Know Before Working Around Suspect Asbestos TSI? Address pre-work asbestos assessments, building surveys, worker awareness, applicable OSHA requirements, work planning, and the importance of not disturbing suspect insulation before appropriate evaluation. Should Asbestos-Containing Thermal System Insulation Be Removed, Repaired, or Encapsulated? Asbestos-containing thermal system insulation does not always need to be removed. The appropriate management decision depends on the material's condition, accessibility, potential for disturbance, building use, and planned renovation or demolition. When material is intact and properly maintained, continued management may be appropriate. When material is damaged, professional repair, encapsulation, or enclosure may be considered. Removal may be appropriate when asbestos-containing insulation interferes with construction, renovation, equipment replacement, or demolition. Encapsulation involves applying an appropriate material to help seal or bind asbestos fibers. Enclosure involves creating a protective barrier around the asbestos-containing material. Neither option is appropriate for every condition. A qualified asbestos professional should evaluate the material and recommend an appropriate management strategy. Chicago and Illinois Asbestos Regulations and Professional Services What Are the Federal, Illinois, and Chicago Asbestos Regulations Governing Thermal System Insulation? Several federal, state, and local regulations may apply to asbestos-containing thermal system insulation. The primary federal workplace regulations include OSHA's General Industry Asbestos Standard, 29 CFR 1910.1001, and Construction Asbestos Standard, 29 CFR 1926.1101. The U.S. Environmental Protection Agency administers federal asbestos requirements, including the National Emission Standards for Hazardous Air Pollutants, commonly called NESHAP. Illinois EPA administers the delegated asbestos NESHAP program in Illinois. The Illinois Department of Public Health administers state licensing requirements for covered asbestos-related activities in schools and public and commercial buildings. Chicago and other local jurisdictions may impose additional notification, permitting, or fee requirements. These regulations address different aspects of asbestos identification, worker protection, project notification, abatement, and disposal. The specific requirements depend on the building, material classification, quantity, work activity, and project location. Is an Asbestos Ins pection Required Before Renovating or Demolishing an Older Building in Chicago or Illinois? An asbestos inspection is generally an important prerequisite to regulated renovation and demolition work, and specific inspection and notification requirements apply under federal and Illinois regulations. Federal NESHAP requires a thorough inspection of affected facilities before covered demolition or renovation operations. Illinois EPA requires advance notification for applicable regulated asbestos removal projects when the amount exceeds specified thresholds. Illinois identifies notification thresholds of more than 160 square feet, 260 linear feet, or one cubic meter of regulated asbestos-containing material for applicable renovation projects. Notification generally must be submitted at least ten working days before the covered work begins. Demolition requirements must be evaluated separately; the notification obligation is not limited to whether asbestos removal is planned. Illinois Department of Public Health licensing requirements and local Chicago or county requirements may also apply. There are specific exemptions and distinctions based on building type and project circumstances, including certain residential structures. Who Is Qualified to Inspect, Sample, and Remove Asbestos-Containing Thermal System Insulation in Illinois? Different asbestos activities require different professional qualifications. An asbestos inspector identifies suspect materials, performs or oversees appropriate sampling, and documents findings. An asbestos project designer prepares specifications and plans for covered abatement projects. An asbestos supervisor oversees applicable abatement operations. An asbestos worker performs regulated asbestos abatement work. An asbestos contractor is responsible for conducting covered abatement projects and meeting applicable licensing and insurance requirements. An air-sampling professional performs appropriate air monitoring and clearance sampling within the scope of their qualifications. In Illinois, the Illinois Department of Public Health administers licensing requirements for asbestos-related activities in schools and covered public and commercial buildings. Property owners should verify the qualifications, licensing, and credentials of the individuals and companies performing the specific work. How do I know if I have asbestos in my home (in floor tile, ceiling tile, shingles, siding, etc.)? The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory. EPA only recommends testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material. Samples should be taken by a properly trained and accredited asbestos professional (inspector). What are the health risks if I have asbestos in my home, building, apartment, or school? Asbestos that is in good condition and left undisturbed is unlikely to present a health risk. The risks from asbestos occur when it is damaged or disturbed where asbestos fibers become airborne and can be inhaled. Managing asbestos in place and maintaining it in good repair is often the best approach. 3.Where can I find someone to remove the asbestos in my home? You can perform an internet search for “asbestos contractor” and the location of your home. Contact your state to determine what state training and accreditation requirements may exist for both the contractor and their workers. EPA recommends that you use an asbestos contractor that is properly trained to handle asbestos. 4.My attic has vermiculite insulation in it. Am I at risk? Should I take it out? If you have vermiculite insulation in your home, you should assume this material may be contaminated with asbestos and be aware of steps you can take to protect yourself and your family from exposure to asbestos. The EPA recommends that vermiculite insulation be left undisturbed. Airborne asbestos fibers present a health risk through inhalation, so the first step is to not disturb the material, which could release fibers into the air. If you disturb the insulation, you may inhale some asbestos fibers. The degree of health risk depends on how much and how often this occurred. If you choose to remove the vermiculite insulation, this work should be done by a trained and accredited asbestos abatement contractor that is separate and independent from the company that performed the assessment of the vermiculite insulation to avoid any conflict of interest. What are the health risks if I have asbestos in my home, building, apartment, or school? Asbestos that is in good condition and left undisturbed is unlikely to present a health risk.

I am thinking about buying a house but it has vermiculite attic insulation in it. Should I have it removed before or after I buy the house? Removal of the vermiculite insulation may not be necessary if it is confined in a manner where it will be left undisturbed. If you choose to have the vermiculite insulation removed, the EPA recommends that you use a trained and accredited asbestos contractor that is separate and independent from the company that performed the assessment of the vermiculite insulation to avoid any conflict of interest. I use/used vermiculite to enhance my potting soil. Should I be concerned? EPA's investigation (see report) into these products indicates that consumers face only a minimal health risk from using vermiculite products at home or in their gardens. To further reduce the risk associated with the occasional use of vermiculite products during gardening activities, EPA recommends that consumers: • Use vermiculite outdoors or in a well-ventilated area. Avoid creating dust by keeping vermiculite damp during use. Avoid bringing dust into the home on clothing. Although EPA does not endorse the use of any particular product, consumers may choose to use: Premixed potting soils, which ordinarily contain more moisture and less vermiculite than pure vermiculite products and are less likely to generate dust. Soil amendment materials other than vermiculite, such as peat, sawdust, perlite, or bark. How do I get certified as an asbestos professional? To become a properly trained and accredited asbestos professional you will need to seek training from a training provider that offers courses approved by the EPA or a state to conduct asbestos training pursuant to the Asbestos Model Accreditation Plan. Most states also require a license to perform this work. Your training course completion certificate is a general prerequisite to applying for such a license. The training courses vary in length from 2 to 5 days depending upon the type of work you wish to perform. Accredited asbestos training courses are offered in five separate disciplines; Asbestos Abatement Worker, Asbestos Abatement Supervisor, Inspector, Management Planner and Project Designer. Some states may refer to these training disciplines by different, yet similar names. Where can I find someone to test a material to see if it contains asbestos? You can perform an internet search for “asbestos inspection and assessment” and the location of your home. Also, make sure that the inspector is properly trained and accredited by your state.

Illinois has some of the highest radon potential areas in the country, with Northern Illinois frequently reporting elevated indoor radon levels. Because radon cannot be seen, smelled, or tasted, testing is the only reliable way to determine whether a property has elevated concentrations. Illinois health guidance recommends taking corrective action when radon levels exceed 4.0 pCi/L. Licensed professional radon measurements provide accurate results and help homeowners determine whether mitigation is necessary. Testing is particularly important during real estate transactions, basement finishing projects, and routine home safety evaluations. What is Radon? Radon is a radioactive noble gas formed from the decay of uranium in soil. It infiltrates structures through: Foundation cracks, Sump pits, Utility penetrations, Crawlspaces and slab joints Once inside, radon accumulates—especially in basements and lower levels. Health Risks: Why is Radon a Serious Threat? #1 cause of lung cancer among non-smokers Linked to thousands of U.S. deaths annually Long-term exposure significantly increases risk There are no immediate symptoms, making testing critical prepare for your radon test How to prepare for a closed building radon measurement: Preparing for a Closed-Building Radon Measurement Steps to Follow Before and During Testing by US Environmental Testing To ensure accurate radon measurement results, follow the steps below before and during the testing period. If you have any questions or concerns, contact US Environmental Testing for assistance. 1. Maintain Closed-Building Conditions Keep all exterior doors and windows closed for 12 hours prior to the start of the test. You may use exterior doors for normal entry and exit as needed. During the testing period, continue to keep all windows, doors, and other openings to the outside closed. 2. Set and Maintain the Indoor Temperature Set your thermostat to 72°F (±5°F) and switch it to "Auto" mode. Do not alter the testing environment in any way. This includes: Opening windows or doors Changing thermostat or fan settings Operating systems that introduce or remove outside air 3. Avoid Activities That May Affect Test Results Avoid using mechanical systems that draw air out of the building, as they can impact the accuracy of the test. Do not move or tamper with any testing devices once placed. If anything occurs that might violate testing conditions—such as unexpected changes to ventilation, HVAC settings, or open windows—immediately report it to US Environmental Testing. If the test conditions are compromised, we may need to conduct a re-test. 4. Do Not Remove Tamper Evident Seals When we place the radon monitors and start the test, we will install tamper-evident seals on all windows. Do not remove these seals until the test concludes. 5. Receive Your Results The test will conclude 48 hours after the start time. At the time of monitor retrieval, we will provide verbal results. Within 24 hours, you will receive a formal report via email or fax. We can also send a hard copy by mail upon request. Following these guidelines ensures the most accurate radon measurement possible.

A picocurie is a unit of radioactivity that is equivalent to one trillionth of a curie. In Perspective, one cure measures the rate of radioactive decay, specifically 3.7 x 10^10 disintegrations per second. What is an Action Level? The EPA recommends fixing homes when radon levels reach 4 pCi/L (150 Bq/m³) or higher. Since no known level of radon exposure is considered safe, the EPA also urges Americans to consider taking action when levels fall between 2 and 4 pCi/L (75–150 Bq/m³).
