British Workers Ignorant to the Dangers of Asbestos

A British Lung Foundation survey has revealed that most tradespeople are unaware of the health risks posed by asbestos. Out of 400 people in this survey relating to asbestos, it was found that 75% had not received any form of asbestos awareness training. The survey showed that asbestos related diseases are currently the main cause of work related ill health. The asbestos related survey estimated that approximately 3000 people die each year due to exposure to the mineral dust.Asbestos was commonly used in the construction of many buildings due to its insulation and fire retardant properties. Asbestos was used in some building materials until 1999; however most was phased out in the early 1980s. Tradespeople now have the highest risk of developing asbestos related lung cancers, mesothelioma and asbestosis as they regularly disturb and come into contact with materials that may contain asbestos fibres. Building owners should always consider having an asbestos survey carried out on their premise. An asbestos survey can help evaluate the presence and extent of any suspect asbestos containing materials in any building and assess their condition.

The British Lung Foundation survey relating to asbestos concentrated on builders, carpenters, plumbers, electricians, joiners and gas fitters. The survey found one in 10 had felt under pressure to continue working even if they had not seen an asbestos survey for the building and suspected that asbestos was present. In addition, nearly a third of those in the survey mistakenly believed that they did not need to see any types of asbestos survey because asbestos had already been removed from all British buildings.

The majority of tradesmen - 81% in the British Lung Foundation’s asbestos survey - said they never, rarely or only sometimes asked if the site they were working on had been checked for asbestos via an official asbestos survey, before they started a job - even though it is a legal requirement for them to see an Asbestos survey which informs them of the presence of asbestos.

Under the Control of Asbestos Regulations 2006, it is a legal requirement that all those that may disturb the fabric of any building must have Asbestos Awareness Training. This form of awareness training for asbestos helps tradespeople increase their general awareness of asbestos within their working environment. It has been estimated that as many as 20 tradespeople die every week as a result of exposure to asbestos in their workplace. In fact exposure to asbestos has been deemed as one of Britain’s biggest workplace killers.

So why isn’t asbestos awareness training a number one priority for all tradespeople because with better training they would reduce their risks of asbestos related lung disease and mesothelioma. However if the British tradespeople continue their ignorance to the dangers of asbestos and don’t put their own health first then campaigns, like those run by the British Lung Foundation, to eliminate asbestos related cancers such as mesothelioma and make them a disease of the past, are a lost cause.

So lets all strive to make our British tradespeople more aware of the dangers of asbestos by making sure asbestos awareness training is a core skill they all own and all tradespeople are presented with an official asbestos survey before they start a job on a particular site.

Australian Workers Report of Mesothelioma

As many as 900 Australians a year may be at risk for death due to mesothelioma cancer because of the rapidly rising number of mesothelioma diagnosis.The Australian workforce once relied heavily on jobs from asbestos-related processing and construction companies and now is finding that they are becoming victims of their one-time employment.

Mesothelioma Death Rates

A professor for the London School of Hygiene and Tropical Medicine used World Health Organization (WHO) figures and found that the UK and Australia both currently lead in the number of mesothelioma-related deaths worldwide.

Professor Julian Peto, head of the Cancer Research UK Epidemiology and Genetics Group, speculated that the death rate from asbestos-related diseases will only increase, especially among men who are currently 40 years of age, and who will become nearly 100 times more likely to die by the time they reach 80 years of age.

Peto also speculated that since the 1980s, there have been approximately 10,000 cases of mesothelioma reported in Australia alone. He also concluded that within the next 40 years, more than 25,000 Australians could die from asbestosis.

Asbestos and Mesothelioma Diagnosis

At its peak, in the 1970s, nearly 10,000 tonnes (equivalent to more than 22 million pounds) of brown asbestos was being imported into Australia for use in the construction industry, largely affecting construction workers, carpenters, plumbers, electricians and shipyard workers.

According to Peto, who presented his findings at a public lecture at the University of Melbourne in April 2008, nearly 500 Australian men and 100 Australian women are diagnosed each year with asbestos-related conditions including mesothelioma cancer.

What is Asbestos and How Does it Cause Mesothelioma?

Vermiculite is a mineral for which asbestos comes from. There are several types of asbestos found throughout the world, and the use of asbestos was wide spread during the 20th century worldwide, as it was a heat-resistant product that was inexpensively produced, offering the construction industry a cheaply made and easily mass produced product.

In Australia, not only was asbestos mined, but it was imported as well. Over the years, any exposure to asbestos may have infected an individual with mesothelioma cancer.

Inhaling asbestos dust may cause mesothelioma cancer, an aggressive form of lung cancer. It is often misdiagnosed and even when symptoms are present, it can be difficult to diagnose.

Often termed “a silent killer” because it remains dormant for years, showing no signs or symptoms in victims. Mesothelioma can be a dormant condition, not revealing symptoms for decades in an individual.

Types of Asbestos

There are six types of asbestos commonly found including, chrysotile (white), amosite (brown), crocidolite (blue), tremolite, anthophyllite and actinolite. Blue, brown and white were the most commonly used types of asbestos. Chrysotile is considered a more flexible form of asbestos and its use was implemented into a range of products including cement roofing sheets for buildings, brake linings, pipe insulation, floor tiles, and even for fire protection within fuses. In the United States, chrysotile is the most common type of asbestos found and a large contributor for mesothelioma there.

Both the brown and blue, amosite and crocidolite asbestos, had been banned in Australia in the 1980s. Crocidolite is also predominately found in Australia and Africa.

Regulations for brown and blue asbestos didn’t occur until the 1980s.

Australian Mesothelioma Treatment Facilities Increase

Due to the high rate of asbestosis cases reported in Australia, with no relief in site, many medical facilities and mesothelioma research centers are setting up headquarters there.

For example, the Asbestos Diseases Foundation of Australia and the Queensland Asbestos Related Disease Support Society are two groups working to offer mesothelioma victims support and information regarding their condition as well as funding for the research of mesothelioma treatments.

While mesothelioma treatment research continues there are no known cures for asbestos-related illnesses. Individuals are advised to speak with an experienced mesothelioma law firm to learn more about developing mesothelioma litigation.

Because of the preventable nature of mesothelioma and the high costs associated with managing the disease, developing a mesothelioma lawsuit may provide monetary compensation as a potential outcome for victims seeking relief.

  1. What is asbestos?
    • Chrysotile, or white asbestos;
    • Crocidolite, or blue asbestos;
    • Amosite, which usually has brown fibers; and
    • Anthophyllite, which usually has gray fibers.
  2. Asbestos” is the name given to a group of minerals that occur naturally as bundles of fibers which can be separated into thin threads. These fibers are not affected by heat or chemicals and do not conduct electricity. For these reasons, asbestos has been widely used in many industries. Four types of asbestos have been used commercially:

    Chrysotile asbestos, with its curly fibers, is in the serpentine family of minerals. The other types of asbestos, which all have rod-like fibers, are known as amphiboles.

    Asbestos fiber masses tend to break easily into a dust composed of tiny particles that can float in the air and stick to clothes. The fibers may be easily inhaled or swallowed and can cause serious health problems.

    Comment: Mesothelioma can be caused by exposure to all types of asbestos.

  3. How is asbestos used?

    Asbestos was mined and used commercially in North America beginning in the late 1800s. Its use increased greatly during World War II. Since then, it has been used in many industries. For example, the building and construction industry has used it for strengthening cement and plastics as well as for insulation, fireproofing, and sound absorption. The shipbuilding industry has used asbestos to insulate boilers, steampipes, and hot water pipes. The automotive industry uses asbestos in vehicle brakeshoes and clutch pads. More than 5,000 products contain or have contained asbestos. Some of them are listed below:

    • Asbestos cement sheet and pipe products used for water supply and sewage piping, roofing and siding, casings for electrical wires, fire protection material, electrical switchboards and components, and residential and industrial building materials;
    • Friction products, such as clutch facings, brake linings for automobiles, gaskets, and industrial friction materials;
    • Products containing asbestos paper, such as table pads and heat-protective mats, heat and electrical wire insulation, industrial filters for beverages, and underlying material for sheet flooring;
    • Asbestos textile products, such as packing components, roofing materials, and heat- and fire-resistant fabrics (including blankets and curtains); and
    • Other products, including ceiling and floor tile; gaskets and packings; paints, coatings, and adhesives; caulking and patching tape; artificial ashes and embers for use in gas-fired fireplaces; plastics; vermiculite-containing consumer garden products; and some talc-containing crayons.

    In the late 1970s, the U.S. Consumer Product Safety Commission (CPSC) banned the use of asbestos in wallboard patching compounds and gas fireplaces because the asbestos fibers in these products could be released into the environment during use. Additionally, asbestos was voluntarily withdrawn by manufacturers of electric hair dryers. In 1989, the U.S. Environmental Protection Agency (EPA) banned all new uses of asbestos; uses established prior to 1989 are still allowed.

    The EPA has established regulations that require school systems to inspect for damaged asbestos and to eliminate or reduce the exposure to occupants by removing the asbestos or encasing it. In June 2000, the CPSC concluded that the risk of children’s exposure to asbestos fibers in crayons was extremely low. However, the U.S. manufacturers of these crayons agreed to reformulate their products within a year. In August 2000, the EPA recommended that consumers reduce possible asbestos exposure from vermiculite-containing garden products by limiting the amount of dust produced during use. The EPA suggested that consumers use vermiculite outdoors or in a well-ventilated area; keep vermiculite damp while using it; avoid bringing dust from vermiculite use into the home on clothing; and use premixed potting soil, which is less likely to generate dust.

    The regulations described above and other actions, coupled with widespread public concern about the hazards of asbestos, have resulted in a significant annual decline in U.S. use of asbestos: Domestic consumption of asbestos amounted to about 719,000 metric tons in 1973, but it had dropped to about 9,000 metric tons by 2002. Asbestos is currently used most frequently in gaskets and in roofing and friction products.

  4. What are the health hazards of exposure to asbestos?

    Exposure to asbestos may increase the risk of several serious diseases:

    • Asbestosis-a chronic lung ailment that can produce shortness of breath, coughing, and permanent lung damage;
    • Lung cancer;
    • Mesothelioma-a relatively rare cancer of the thin membranes that line the chest and abdomen; and
    • Other cancers, such as those of the larynx, oropharynx, gastrointestinal tract, and kidney.
  5. Who is at risk?

    Nearly everyone is exposed to asbestos at some time during their life. However, most people do not become ill from their exposure. People who become ill from asbestos are usually those who are exposed to it on a regular basis, most often in a job where they work directly with the material or through substantial environmental contact.

    Since the early 1940s, millions of American workers have been exposed to asbestos. Health hazards from asbestos fibers have been recognized in workers exposed in shipbuilding trades, asbestos mining and milling, manufacturing of asbestos textiles and other asbestos products, insulation work in the construction and building trades, brake repair, and a variety of other trades. Demolition workers, drywall removers, and firefighters also may be exposed to asbestos fibers. As a result of Government regulations and improved work practices, today’s workers (those without previous exposure) are likely to face smaller risks than did those exposed in the past.

    Although it is known that the risk to workers increases with heavier exposure and longer exposure time, investigators have found asbestos-related diseases in individuals with only brief exposures. Generally, those who develop asbestos-related diseases show no signs of illness for a long time after their first exposure. It can take from 10 to 40 years for symptoms of an asbestos-related condition to appear.

    There is some evidence that family members of workers heavily exposed to asbestos face an increased risk of developing mesothelioma. This risk is thought to result from exposure to asbestos fibers brought into the home on the shoes, clothing, skin, and hair of workers. This type of exposure is called paraoccupational exposure. To decrease these exposures, people exposed to asbestos at work are required to shower and change their clothing before leaving the workplace.

  6. How great is the risk?

    Not all workers exposed to asbestos will develop diseases related to their exposure. The risk of developing asbestos-related diseases varies with the type of industry in which the exposure occurred and with the extent of the exposure. Asbestos that is bonded into finished products such as walls and tiles poses no risk to health as long as it is not damaged or disturbed (for example, by sawing or drilling) in such a way as to release fibers into the air. When asbestos fibers are set free and inhaled, however, exposed individuals are at risk of developing an asbestos-related disease.

  7. How does smoking affect risk?

    Many studies have shown that the combination of smoking and asbestos exposure is particularly hazardous. Smokers who are also exposed to asbestos have a greatly increased risk of lung cancer. However, smoking combined with asbestos exposure does not appear to increase the risk of mesothelioma.

    There is evidence that quitting smoking will reduce the risk of lung cancer among asbestos-exposed workers. People who were exposed to asbestos on the job at any time during their life or who suspect they may have been exposed should not smoke. If they smoke, they should stop.

  8. Who needs to be examined?

    Individuals who have been exposed (or suspect they have been exposed) to asbestos fibers on the job or at home via a family contact should inform their physician of their exposure history and any symptoms. Asbestos fibers can be measured in urine, feces, mucus, or material rinsed out of the lungs. A thorough physical examination, including a chest x-ray and lung function tests, may be recommended. It is important to note that chest x-rays cannot detect asbestos fibers in the lungs, but they can help identify any lung changes resulting from asbestos exposure. Interpretation of the chest x-ray may require the help of a specialist who is experienced in reading x-rays for asbestos-related diseases. Other tests also may be necessary.

    As noted earlier, the symptoms of asbestos-related diseases may not become apparent for many decades after exposure. If any of the following symptoms develop, a physical examination should be scheduled without delay:

    • Shortness of breath;
    • A cough or a change in cough pattern;
    • Blood in the sputum (fluid) coughed up from the lungs;
    • Pain in the chest or abdomen;
    • Difficulty in swallowing or prolonged hoarseness; and/or
    • Significant weight loss.

  9. How can workers protect themselves?

    Employers are required to follow regulations dealing with asbestos exposure on the job that have been issued by the Occupational Safety and Health Administration (OSHA), the Federal agency responsible for health and safety regulations in maritime, construction, manufacturing, and service workplaces. The Mine Safety and Health Administration (MSHA) enforces regulations related to mine safety. Workers should use all protective equipment provided by their employers and follow recommended work practices and safety procedures. For example, National Institute of Occupational Safety and Health (NIOSH)-approved respirators that fit properly should be worn by workers when required.

    Workers who are concerned about asbestos exposure in the workplace should discuss the situation with other employees, their employee health and safety representative, and their employers. If necessary, OSHA can provide more information or make an inspection. Regional offices of OSHA are listed in the “United States Government” section of telephone directories’ blue pages (under “Department of Labor”). Regional offices can also be located at http://www.osha-slc.gov/html/RAmap.html on the Internet, or by contacting OSHA’s national office at:

  10. Will the Government provide examinations and treatment for asbestos-related conditions? What about insurance coverage?

    Medical services related to asbestos exposure are available through the Government for certain groups of eligible individuals. In general, individuals must pay for their own medical services unless they are covered by private or Government health insurance. Some people with symptoms of asbestos-related illness may be eligible for Medicare coverage. Information about benefits is available from the Medicare office serving each state. For the telephone number of the nearest office, call toll-free 1-800-633-4227 (1-800-MEDICARE) or visit http://www.medicare.gov on the Internet.

    People with asbestos-related diseases also may qualify for financial help, including medical payments, under state workers’ compensation laws. Because eligibility requirements vary from state to state, workers should contact the workers’ compensation program in their state. Contact information for the workers’ compensation program in each state may be found in the blue pages of a local telephone directory or at http://www.dol.gov/esa/regs/compliance/owcp/wc.htm on the Internet.

    If exposure occurred during employment with a Federal agency (military or civilian), medical expenses and other compensation may be covered by the Federal Employees’ Compensation Program. Workers who are or were employed in a shipyard by a private employer may be covered under the Longshoremen and Harbor Workers’ Compensation Act. Information about eligibility and how to file a claim is available from:

    Organization: Office of Worker’s Compensation Programs
    Employment Standards Administration
    U.S. Department of Labor
    Address: Room S-3229

    Workers also may wish to contact their international union for information on other sources of medical help and insurance matters.

    Eligible veterans and their dependents may receive health care at a Department of Veterans Affairs (VA) Medical Center. Treatment for service-connected and nonservice-connected conditions is provided. If the VA cannot provide the necessary medical care, they will arrange for enrolled veterans to receive care in their community. Information about eligibility and benefits is available from the VA Health Benefits Service Center at 1-877-222-8387 (1-877-222-VETS) or on the VA Web site at http://www.va.gov/health_benefits on the Internet.

  11. Is there a danger of nonoccupational exposure from the environment and products contaminated with asbestos fibers?

    Asbestos is so widely used that the entire population has been exposed to some degree. Air, drinking water, and a variety of consumer products all may contain small amounts of asbestos. In addition, asbestos fibers are released into the environment from natural deposits in the earth and as a result of wear and deterioration of asbestos products. Disease is unlikely to result from a single, high-level exposure, or from a short period of exposure to lower levels of asbestos.

  12. What other organizations offer information related to asbestos exposure?

    The organizations listed below can provide more information about asbestos exposure.

    The Agency for Toxic Substances and Disease Registry (ATSDR) is responsible for preventing exposure, adverse human health effects, and diminished quality of life associated with exposure to hazardous substances from waste sites, unplanned releases, and other sources of pollution present in the environment. The ATSDR provides information about asbestos and where to find occupational and environmental health clinics. The ATSDR Information Center can be reached at:
