The paper "Aspects of Asbestos Control" is a great example of a finance and accounting research paper. Using asbestos in construction and renovation of any building is not recommended. Although asbestos use is illegal, it is approximated that over 1.5 million properties in workplaces still have some quantity of asbestos. Most educational facilities undoubtedly have asbestos, though not known by staff until refurbishments and repairs are conducted. This paper discusses aspects of asbestos by focusing on its control. It will conclude by summarizing the aspects of asbestos control. Background information Asbestos occurs in different forms.
The most common types of asbestos found in buildings are blue, brown, and white asbestos. A typical example is chrysotile that is also called the white asbestos (CHR). This form belongs to the serpentine group, a type that is most common and therefore most used (Van Gosen, 2007). Its properties include most flexibility, soft, abundant, spun woven, and fiercest heat. The diagram below represents a picture of this form (Beard & Rook, 2000). Chrysotile (white) asbestos (CHR) (Picture x 10 magnifications - cement based sheeting with white asbestos) The second form of asbestos is the Amosite or brown asbestos (AMO) this type belongs to the amphibole category but also called grey or brown form.
Its features include resistance to heat, harsh spiky fibres, coarse nature, and good tensile strength (Van Gosen, 2007). A pictorial presentation of this form is shown below. Amosite (brown) asbestos (AMO) (Picture x 25 magnification - low-density board mix of brown and white asbestos) The least common form of asbestos is the crocidolite or the blue asbestos (CRO). This form belongs to the amphibole category. Its features include needle-like fibres, high resistivity to acids, strongest, and the ability to be stiffer as well as straight.
Its pictorial presentation is shown below. Crocidolite (blue) asbestos (CRO) (Picture x 25 magnification – cement based sheeting with blue asbestos) The white asbestos is the least dangerous of the three. It is advisable that if any building including a school or college built or renovated prior to 1985, be assumed to contain asbestos unless the contractors prove otherwise through appropriate testing. The most common route of entry of this substance into the body is inhalation.
Inhaled fibres become lodged within the lungs, this will expose the victim to several detrimental health effects like scarring as well as inflammation. The aftermath is interfered breaking leading to diseases. The most common side effects include non-malignant, mesothelioma, and lung cancer. The severity of effect depends on the exposure duration, concentration, the frequency, chemical makeup shape, and size of fibres inhaled (Roach et al. , 2002; Van Gosen, 2007). It is common to find materials containing asbestos in places like construction sites, asbestos mining sites, most processing plants (Sullivan, 2007).
Some of the common items in construction sites containing asbestos are roof cement plastic containers, asbestos cement sheets, and asbestos sheet joints shown in the pictures below. Employer’ s task in the control of asbestos It is the responsibility of employers to ensure that there is maximum control of asbestos in the work environment. They need to examine the workplace to verify if there is any asbestos present, what type of asbestos is present (if any), and what condition it is in. They also need to assume that all materials contain asbestos unless proven otherwise and keep a record of the asbestos location at all times.
A risk assessment test on all the components containing asbestos should be undertaken and a written plan drawn to control asbestos in places of work (Circo & Little, 2009). Actions to avoid and control contact of asbestos with staff and other people like students and pupils are worth instituting. These actions need frequent reviews and monitoring. In case of any clarifications on asbestos, trade union safety representatives would need consultation. Safety precautions and signs on asbestos should be put in places containing asbestos, to warn anybody likely to go near it.
It is Queensland educational policy that no one should be on the school site when asbestos removal is taking place. Any work or repairs that may bring about contact to asbestos should be conducted unless it has been verified if asbestos is present, the kind present, its material, and its condition. A copy of the asbestos policy in schools (such as the School’ s Built Environment Materials Information Register [BEMIR] Report) and colleges should be requested by safety representatives, containing information on the location of asbestos and measures that have been taken to supervise the position (Greene, 2005).
If there is not enough information within available reports, further testing should be undertaken prior to any works commencing. Removal of asbestos If asbestos is located in a building and will not be disturbed, typically the asbestos is acceptable to stay undisturbed. However, if the asbestos is going to be disturbed, then an asbestos specialist should be engaged to determine the appropriate method of removal (Lampl, 2006). It is important to note that asbestos removal is required to be undertaken by an expert in this field.
Furthermore, it is also important that the area of disturbance is not accessible to those parties not qualified as personal health can be affected. After the removal of asbestos, the area should be tested to ensure that the area has not been contaminated before reoccupation (Oberta, 2005).
