Professional Asbestos Removal for a Safe and Clean Environment

Leave a Comment

Asbestos is a hazardous mineral fiber known for its heat resistance and insulating properties. Prolonged exposure to its fibers can lead to serious health risks, including lung diseases like lung cancer, asbestosis, and mesothelioma. Due to their harmful effects, the removal and disposal of asbestos-containing materials must be handled by trained professionals following specific safety protocols.

This article will explore the dangers associated with asbestos exposure and its health effects. It will also examine the methods and safety protocols used by asbestos removal contractors during removal and abatement processes.

Common Asbestos-Related Dangers

Respiratory Issues

Inhalation of asbestos fibers can lead to various respiratory problems. Asbestos exposure is linked to the development of asbestosis, a chronic lung disease characterized by scarring of lung tissue. This can cause breathing difficulties and respiratory failure over time.

Lung Cancer

Inhaled asbestos fibers can cause inflammation and scarring in the lungs, eventually leading to the formation of cancerous tumors. Smokers who are exposed to asbestos have a particularly high risk of developing lung cancer.


Asbestos exposure is the only known cause of mesothelioma, a rare cancer that affects the lining of the lungs, abdomen, or heart. The latency period for this disease can be decades, with symptoms often not appearing until it has reached an advanced stage.

Asbestos-Related Pleural Disease (ARPD)

ARPD encompasses various non-cancerous lung conditions caused by asbestos exposure, including pleural plaques, thickening, and effusion. While these conditions may not be life-threatening, they can cause discomfort and impair lung function.

Gastrointestinal and Other Cancers

Asbestos exposure has been associated with an increased risk of developing cancers of the esophagus, stomach, colon, and other organs. Although less common than lung-related diseases, these cancers are still significant health risks for individuals exposed to asbestos.

Secondary Exposure Risks

Before the dangers of asbestos were fully known, individuals who lived with asbestos workers or who regularly came into contact with asbestos-contaminated environments, faced health risks through secondary exposure. Fibers can cling to clothing, skin, and hair, potentially exposing family members and others in the vicinity to asbestos dust.

Methods and Protocols Employed by Asbestos Removal Contractors

The following methods and protocols help asbestos removal contractors effectively mitigate the risks associated with exposure:

Risk Assessment

An environmental hygienist will evaluate the site, and conduct sampling to determine the extent of contamination and location of asbestos, and make recommendations for removal or abatement. A tailored removal plan will ensure that all necessary precautions are taken to minimize risks, protect occupants and the environment, and guard against hazards to workers. The hygienist may conduct final clearance sampling to confirm that the asbestos has been safely and properly removed.


Containment prevents the spread of asbestos fibers and minimizes the risk of exposure to workers and the public. Asbestos removal contractors use containment barriers, such as heavy plastic sheeting and negative air pressure systems, to seal off the area and isolate asbestos-containing materials. This eliminates the potential for airborne dispersion and secondary contamination.

Personal Protective Equipment (PPE)

During remediation activities, PPE is essential for minimizing worker exposure to airborne asbestos fibers. Contractors provide workers with appropriate PPE, including respirators with high-efficiency particulate air (HEPA) filters, disposable coveralls, gloves, and protective eyewear. Proper training, fit-testing and a medical evaluation for wearing a respirator must be completed before any worker can be exposed to an asbestos work environment.

Wet Methods

Wet methods suppress the release of airborne fibers and minimize the risk of exposure to workers and the surrounding environment. Asbestos removal contractors utilize misting or spraying techniques to completely wet down the asbestos-containing materials before any removal. Surfactants are added to water to promote penetration into the material and to prevent fiber dispersion into the air.

Careful Handling and Disposal

After removal, asbestos-containing materials (ACM) are handled with extreme care to prevent fiber release and minimize the risk of exposure to the environment. Contractors adhere to strict protocols for containing, labeling, and transporting asbestos waste to a permitted disposal facility.

Decontamination Procedures

After completing asbestos removal tasks, workers undergo procedures to remove any fibers adhering to their PPE or clothing. Decontamination units have showers and clean changing areas to facilitate the safe removal and disposal of contaminated PPE. These are critical for protecting workers, preventing secondary exposure risks, and ensuring that asbestos removal projects are conducted safely.

Insulation for Maximum Performance in Facilities

Leave a Comment

Insulation Uses:

  1. Thermal control: Prevents heat gain or loss. Keeps processes at a controlled regulated temperature.
  2. Freeze Protection: For water systems susceptible to below-freezing temperatures, insulation in combination with electric heat tracing is a technique used to prevent ruptured pipes and equipment.
  3. Condensation control: Prevents sweating or water buildup on the surface or other areas of a facility
  4. Fireproofing and protection of mechanical systems from corrosion, ultraviolet light, impact, heat, dust and debris
  5. Personnel Protection: Protects those working around these systems from burns, extreme cold and caustic and acidic environments.
  6. Energy efficiency and cost savings: Prevents wasted energy from leaving the system and added cost to replace that energy. Easy to calculate investment payback and savings from year to year.
  7. Acoustics: Reduction in facility noise levels from circulation of fluids in piping, air velocity in ductwork and vibration caused noises in a system.

Types of Insulation


Fiberglass and Mineral wool are produced by taking glass or basalt type rocks, melting them and spinning the fibers into a mat or board or pipe shape. Fibrous insulations have a wide temperature range making them useful for multiple applications in a facility. They have moderate to good R-values per inch and are easily fabricated using knives or scissors.

Closed Cell Foams

These insulations can be flexible and rubber-like, such as Armaflex and K-flex, for use on piping,and curved surfaces of ducts and equipment. They can also be rigid foams such as Foamglas ( cellular Glass), Polyisocyanurate, phenolic foam or extruded polystyrene foam-boards. Typically these foams have a better R-value than fibrous insulation and maintain that characteristic by not retaining moisture in their unique cell structure. They are typically not suitable for higher temperatures.

Open Cell Foams

These can be spray applied foams which can fill large cavities, or polyimide foams which are flexible/bendable and have excellent fire protection capabilities. Open-cell foams can absorb and retain some moisture so protection is required to avoid this issue. They typically have good R-values per inch. and are easily fabricated.


These insulations rely on reflecting radiant heat either away from the source or directing it to the source. They are usually very flexible and have applications on piping, ductwork and building insulation. They are clean and easy to fabricate, with moderate R-values per inch.


These insulations are often dusty and difficult to fabricate or bend, however, they maintain the highest R-value levels per inch and therefore can be readily used in tight areas where there is limited space for thicker insulations.

Cryogenic Systems

Cryogenic insulation involves maintaining extremely low temperatures for storing or transporting cryogenic liquids like liquefied natural gas (LNG) or liquid nitrogen. Materials like foams, aerogels, and multilayer insulation are employed to minimize heat transfer and prevent temperature fluctuations. This approach ensures the safe operation of industrial processes involving the handling of cryogenic fluids.

Insulation Jacketing

Insulation jacketing covers insulation materials with protective jackets or wraps, typically made from metal, PVC, or other durable materials. These jackets provide mechanical protection against physical damage, weathering, corrosion, and UV exposure, extending the lifespan of insulation systems.

Vacuum Insulation Panels (VIPs)

VIPs comprise a core material enclosed in a gas-tight envelope, with the air evacuated to create a vacuum. This reduces heat transfer through conduction and convection. Despite their thin profile, VIPs offer high thermal resistance, making them ideal for space-constrained industrial projects, appliances, equipment and areas with limited insulation thickness allowances.
