Evaluation of Risk Due to Noise Hazard and Control

Question: Discuss about the Evaluation of Risk Due to Noise Hazard and Control. Answer: Introduction Physical hazards can be any factor that can cause harm to the body without actual physical contact with the body. There are number examples which come under the category of corporal hazards like continuous loud noise and vibration, radiation, heights, pressure, extreme temperatures (Loftis, 2007). Noise and vibrations linked with each other as it originates from a vibrating object. Noise and vibrations have related physics as they are transmitted in the form of waves. The noise hazards have grave health impacts and most of the workplaces expose to noise, the louder it is, and it can cause more damage to the extent of temporary to permanent loss of hearing. This report discusses the potential risk of the physical agent noise to employees at the organization Ooredoo, Qatar and specifies the prevention and control approach that should be implemented. Organizations require a noise management plan as noise inconvenience will not go away if ignored and they are likely to get worse if not d ealt. The purpose of this paper is to lead through those measures. Evaluation and Potential Risk Noise is the most common physical agent causing occupational health hazards. This physical agent can be found in industrial and manufacturing environments, while farming, in cafeterias and permanent auditory loss, is the key health concern. Infuriation, constant worry, and interference with verbal communication are the key concerns in noisy offices, schools, and computer rooms. Potential hazards to the employee can be a hearing loss depends on the force of the noise, its extent, and how repeatedly the exposure occurs. This physical agent is an undesired sound which could cause damage to the health of the employees or hearing impairment. Different kinds of noise have kind of effects on the health of the employees at workplaces. The key areas having noise troubles are recognized, including the music and entertainment segment. Some of the chronic health effects due to exposure to the noise hazard at workplace over the years may lead to irreparable hearing failure if the everyday sound e xposure level gets to or go beyond 85 dB(A) (Osha.gov, 2016).Consequent exposure to blare causes the symptoms to be getting appalling over a period. Noise can be issue at the place of work if there is a ringing or humming sound in the ears when workers have left work or people have to shout to their co-workers who at arms length from them. Deafening blare can be the grounds for hearing loss both gradually, and by exposures in a given time period. Harm can happen instantaneously by exposure to extreme reverberation produced by a likely to explode sounds like firing of guns, explosion or cartridge operated equipment. Noise is the menacing of the entire industrial noxious waste, concerning all industry and basis of harsh hearing failure in many countries. Anybody could be vulnerable to unwarranted noise levels. People employed in loud workplaces, industrial units and plants, cell phone companies, and the sharp ear-splitting environments such as repair of roads, airports, and erection site are most vulnerable to this peril. The potential risks faced by workers at the organization Ooredoo, a cell phone company in Qatar. There has been an increasing demand for quicker cell phone service and network speeds have resulted in an increase in communications tower work that has resulted in increased risk for workers in Ooredoo. Over the last decade, mobile phone usage has matured exponentially with the introduction of better communication processes and systems and better phone. Nevertheless, how much people use cell phones these days, that doctor testify that most of hearing loss among users. Too much use of cell phones can cause the dangerous of health hazards for its user like hearing loss, neuroendocrine disruption, hormonal imbalance, and c ancer amongst the many harmful effects. Some of their potential risk faced by the workers of Ooredoo could be the dangerous radiation emitting from the cell phone towers (?liwi?ski, 2013). The workers are bared to the following risk of the auditory system, permanent and temporary audio failure, tinnitus, hearing impairment, noise management steps in the area of work, closed spaces, hurdles, and different kinds of unsafe working environment. Laws and Regulations The Qatar State Environmental Protection Law (2002), Annex (3/ 5th), provides maximum allowable ambient noise limits in Qatar. Noise disorder is created with the appliances and apparatus used especially the generator sets, should not increase more than the maximum limit of dB levels, as per rule when sleeping it should not more than40 dBA max; entertainment 45 dBA is the limit; Eating outlets up to 45 dBA . Vibration restrictions can be according to the BS 6841 (*d,e) (Osha.gov, 2016). A member of staff or employee is under obligations by the set of laws to use the hearing guard, a company or service provider shall make available permit hearing protectors. Where feasible, the company or the contractor shall make sure that a hearing protection is provided under the subsection which diminish the sound levels received into the workers ears can be up to 85 dBA only(Qf.org.qa, 2016). The Qatar Labour Law endorses the minimum standard of rights and advantages for employees to which the employers must adhere as well as the obligations of employees working in Qatar. The Laws of country safeguard the workers against the health hazards and following are some of the rules are put in place. The corporation should provide wide-ranging medical insurance to its workers. The company shall make available all-inclusive medical insurance to his workers. The company will be responsible for the compensation of Workers health insurance. Workers, who are at risk to the work-related perils, shall undergo regular health checkups in accordance with the recognized medical rules and the expenditure to be borne by the organization (Sudan et al., 2013). The company is required to pay the salaries and wages to its workers if they are undergoing any medical treatment caused due to occupational hazards as per the law (Kopke, 2007). The criterion for health care conveniences in the boarding and lodgings of workforce are also established. The noise hazard signage should be appropriately used. Where noise levels, whether ambient noise or occupational noise, exceed limits s tipulated in the Qatar State Environmental Protection Law (2002), appropriate hazard signage should be posted to inform workers, students, visitors, contractors and others who might be exposed to this physical agent. The language of this signage should be understood by everybody and also notify the concerned of the requirement of the protection (Canfeng, Shujie, and Dong, 2012). Training shall be imparted to the workers exposed to noise hazard above the limits stipulated in the Qatar State Environmental Protection Law (2002) and such training would be provided during induction. Prevention and Control Strategy Exposure to hazard and its prevention and control in the workplace requires knowledge and inventiveness. Effective control usually does not necessarily require expensive and complex measures (Jacques, 2009). Risk control can be achieved through right technology, which can be very simple. It can also consist of simple improvements and changes such as placing an impermanent barrier between an ultraviolet source and an employee, or training staff in secure work practices(Tak, Davis, and Calvert, 2009). The physical agent -noise, is a considerable physical vulnerability, which can be curbed by a range of methods (Price, 2012). The effect of clamor danger can be compacted by settling types of gear and frameworks that have been built, outlined, and worked to work indistinctly; by encasing or protecting commotion making hardware and by taking definite steps so that paraphernalia is in good state and suitably maintained with all damaged and unstable parts reinstated; by keeping noisy apparatus and machinery at higher levels to decrease the disturbance. Furthermore, the workplaces should also install silencers, mufflers, or baffles. The organizations should hire an occupational hygienist who should be able to foresee the potential health hazards that may result from workplaces business processes and its operations and equipment used, and accordingly advise the organization on planning and designing their hazard free workplace (Stanbury, Rafferty, and Rosenman, 2008). The hygienist should be able to distinguish and understand, in the work environment, the happening (real or impending) of chemical, physical and biological causes and stresses, and their interactions with other aspects, which could have an effect on the health and welfare of personnel. Constant evaluations, throughout the environmental monitoring and health supervision, should be the part of any risk prevention and control strategy (Menounou and Papaefthymiou, 2009). The strategy to be followed for prevention and controlling the risk posed due to noise should have the following three stages. Firstly should be observation at the workplace by the workers or employees and to recognize the problem, find out the simple and straight forward solutions for risk identified and seek assistance and aid when required. Secondly, to analyze the hazard with the help of an occupation health consultant which is more complex but would the right information. (Reza Monazzam and Momen Bellah Fard, 2011). To prevent noise in affecting the workers, the noise path should be customized by erecting enclosures around the machines and equipment to curb the amount of noise that is being emitted in the workplace setting. Barriers can also be put up to block the path of the noise or disturbance and also by positioning the noise sources far away from the workers. A few strategies to control commotion at source are a case, by utilizing the sound-deadening or suppressing, clamor boundaries, and disengagement. To get the authoritative commotion control measures e.g. preparing and training, work pivot, upgrading the lists to reduce the quantity of representatives being presented to clamour (Chalupka, 2013). To make accessible a defensive gear and contraptions (PPE) case, ear covers, and earplugs. Then again, if specialists are always required to carry PPE to lessen the danger of listening to misfortune from a commotion contact that surpasses the introduction standard, then an audiometric testing fr amework must be set up in the association (Kurmis and Apps, 2007). The next step in prevention and controlling is reviewing the measures implemented regularly and revised or updated regularly, to the measure are working as planned and minimize the risk of exposure to the physical agent being discussed and to continuously maintain the workplace environment (Lin, Nassar, and Evans, 2013). To control the hazard the regular noise surveys should be scheduled to understand the concerns of the noise levels. Keeping the workers informed regarding where the noise exposure is above the upper exposure action value and offered relevant information regarding from hearing protection is procured or can be provided, make available appropriate training and instructions on right fitting, maintenance and suitable storage space (Stanbury, Rafferty, and Rosenman, 2008). Assessing the utility of hearing protectors the SNR method. The SNR is the simplest prediction way, and it uses the SNR value repeatedly provided with their products by hearing protection sellers. The measurement that is required is of the C-weighted sound pressure level at the working spot. The SNR value is subtracted from the C-weighted level to get a prediction of the A-weighted protected level Conclusion The example of auditory health hazards could be acoustic trauma, tinnitus, hearing impairment, temporary or permanent. To handle the with noise hazard, there is a need to follow a methodical series of steps and continuously evaluate monitor, re-implement if required and control it. Noise could be safety risk which can distract attention. It can go down out the sound of an out of order machine, an alarm indicator or somebody shouting. People find that this physical agent adds to the weariness of work and also makes it difficult to focus. Productivity can be impacted as a result. Failing to take action on the predicament of noise, jeopardize the hearing damage and add on costs as per the serious fines under the Health and Safety in Employment Acts of various countries. Workers can lodge a claim for compensation with the ACC for hearing dent caused by noise at the workplace, which will have consequential financial penalties for the organization. Rehabilitation costs are incurred if a wo rker or employee needs to be retrained and relocated. Organisations should allocate funds on the management of noise which could attract an investment, to ensure dependable occupational health and safety practice in the workplace; to comply with legal obligations and to reduce the organizations liability through compensation or claims. To provide a safer, more dynamic and satisfying working environment; minimize the chances of workforce hearing being afflicted with hearing disorders and improve the image the workplace or organization in acting responsibly towards its workers (Dube, Ingale, and Ingale, 2011).
