Asbestos

Asbestos meaning

Asbestos is a generic name for a group of natural materials. It had commercial advantage in the past due to its extraordinary resistance to tensile strength, poor heat conductivity, and relative resistance to chemical attacks. Asbestos is carcinogenic to humans, and may cause mesothelioma, lung cancer, and laryngeal and ovarian cancers. It may cause other diseases, such as asbestos disease (pulmonary fibrosis), lung membrane plaques, thickenings and effusions.

Asbestos symptoms

The effects of long-term exposure to asbestos usually do not appear until 10 to 40 years after the initial exposure. Symptoms can vary. Other signs and symptoms of asbestos may include :

  • shortness of breath
  • Dry and chronic cough
  • With loss of appetite and weight loss
  • Forefoot and toenails appear larger and more rounded than usual (clubbing)
  • Chest tightness or pain

Asbestos exposure

If you are exposed to high levels of asbestos dust over a long period of time some airborne fibers can settle inside the alveoli which are the small sacs inside your lungs where oxygen is exchanged for carbon dioxide in the blood. Asbestos fibers irritate and scar the lung tissue, leading to hardening lungs and this makes breathing difficult.

As asbestosis progresses, more and more lung tissue becomes scarred, and eventually lung tissue becomes too stiff to contract and expand normally.

Smoking appears to increase the retention of asbestos fibers in the lungs, often leading to faster disease progression.

If you have asbestosis, you are at increased risk of lung cancer, especially if you are a smoker or have a history of smoking. Rarely, cancer of tissue around the lung occurs after many years of exposure to asbestos.

People with asbestosis also have a higher risk of developing other serious conditions, such as :

  • Pleurisy is the thickening of the lining that covers the lungs, ie the pleura.
  • Mesothelioma is a cancer of the lining of the lungs, abdomen, heart or testicles.
  • Lung Cancer.

Asbestos removal

Reducing exposure to asbestos is the best way to prevent asbestosis. In the United States of America, federal laws require that employees of industries that deal with asbestos products, such as the construction industry, take special safety measures.

Many homes, schools, and other buildings built before the 1970s contain materials that contain asbestos, such as pipes and floor tiles. In general, there is no danger of exposure to asbestos as long as it is surrounded and not rubbed. However, when materials containing asbestos are damaged, there is a risk of asbestos fibers being released into the air and inhaled.

There is no treatment to reverse the effects of asbestos on the alveoli. Instead, treatment focuses on slowing the progression of the disease, relieving symptoms, and preventing complications.

You’ll need regular follow-up care, such as a chest X-ray or CT scan and lung function tests, at regular intervals depending on the severity of your condition.

Your doctor may prescribe supplemental oxygen therapy to relieve difficulty breathing caused by advanced asbestosis. This treatment is given through a thin plastic tube with a tooth root inserted into the nostrils, or a thin tube connected to a mask worn over the nose and mouth.

Participation in a pulmonary rehabilitation program may help some people. This program consists of educational and other materials explaining exercises such as breathing and relaxation techniques, ways to improve physical activity habits, and a culture of improving general health.

If your symptoms are severe, you may be a candidate for a lung transplant.

Abestos test

Asbestos is a natural mineral composed of fine, tightly packed fibers. Due to its strength, asbestos is commonly used in the manufacture of insulation, fireproofing and other building materials. Unfortunately, asbestos has been found to pose a serious health hazard when its fibers become loose and airborne, as inhaling it can cause scarring of the tissue lining mesothelioma in the lungs and even lung cancer. You can check for signs of asbestos yourself, but the test must be carried out by a certified professional using special equipment. If asbestos is present, have a contractor repair or remove materials that contain it to ensure the safety of the people using the building.

  1. Determine the construction time of the building in question. Asbestos was used extensively between 1920 and 1989, after which the Environmental Protection Agency (EPA) began regulating materials containing asbestos. Asbestos can be commonly found in buildings, but also in gas heaters, hair dryers, some clothing, and car brakes.

Walls, floors, pipes, woven paints, insulation, fire-retardant materials, pipes, electrical wires, and even boards built between 1920 and 1989 may contain asbestos. If the building was constructed between 1920 and 1989, it is likely that something in the building was constructed with asbestos-containing materials.
Few of the materials made today are made of asbestos. Items containing asbestos are now classified as such.

2. Check for signs of disturbed asbestos material. You can’t tell if an item contains asbestos just by looking at it. Instead, look for warning signs of deteriorating building materials. Asbestos isn’t dangerous when it’s in good condition, but when it begins to decompose and the fibers are released into the air, it becomes toxic. Look for signs of old materials that have become worn or damaged.

Disintegration of pipes, insulation, walls, tiles, vinyl floors, stove pads, and other old materials that have been in the building since its construction are signs to look out for.
Look for cracks, dusty areas, and spots where the material appears to be in the process of crumbling and crumbling

3. Decide if you want to test the area. If you don’t see signs of building material deteriorating, you may not need to test the area, as asbestos is only dangerous when it becomes airborne. However, if you see signs of offensive material, or if you simply want to err on the side of safety, you should opt for area testing by a certified professional for asbestos testing and handle it safely.

Another scenario in which you may want to test the area is if you plan to do new construction or replace old materials. Even if the materials are still in good shape, they will be disturbed during the construction process and may release fibers into the air.
While you can purchase the equipment required to perform an asbestos test, it is not recommended that you try it yourself. Asbestos testing must be performed by a person who has undergone training and knows how to handle the material without causing health hazards to the building occupants. If you haven’t trained, you could end up disturbing and inhaling asbestos or putting others at risk of doing so.

Asbestos siding

Owning an older home in the Delaware Valley raises the possibility that its siding may contain asbestos. Houses constructed prior to 1979 could have this hazardous material in the siding. Asbestos was commonly used as an insulating and fire-retarding additive in building materials. However, not every manufacturer used it, and building age alone does not automatically mean your home has asbestos. When you’re wondering how to identify asbestos siding, you begin by determining your home’s age. If the siding materials appear suspect, then you’ll ultimately need a laboratory test to confirm the presence of asbestos.

HOW TO IDENTIFY ASBESTOS SIDING

  • Determine the age of your home by looking at the property deed or any other records about its construction.
  • Inspect your siding.
  • Look specifically for any printed information that identifies the siding manufacturer or date of installation.
  • Most siding created after the 1960s did not include asbestos.
  • Count layers of paint because many layers indicate age and therefore a greater chance of asbestos.
  • Examine areas around replaced windows and doors if they have newer siding next to them.
  • Examine areas around replaced windows and doors if they have newer siding next to them.
  • Compare the newer siding to older siding areas and look for evidence that indicates age.
  • Asbestos was particularly prevalent in siding that resembles shingles or was made to look like wood grain.
  • If your siding has these characteristics, then asbestos could be present.
  • You may choose to take a sample of siding from a damaged area of siding.
  • Put on a mask and scrape away some siding material into a baggie.
  • Contact an accredited testing lab in your area to analyze your sample.
