Personal Protective Equipment in Safety and Health Essay Example for Free

Personal Protective Equipment in Safety and Health Essay This involves imposing a barrier (physical barrier or distance) between the hazard and the worker. Local and General Ventilation is used to dilute or divert toxic contaminants from the workers. ADMINISTRATIVE CONTROL Safe operating procedures (SOP), Shift work and training of workers can reduce the risk to the workers handling chemicals. PERSONAL PROTECTION EQUIPMENT If it is not possible to reduce chemical hazards to an acceptable level, by either elimination or guarding/isolation, the worker should be given certain protective equipment to prevent contact of the hazards with the body. This equipment forms a barrier between the toxic and the route of entry. Failure of equipment means immediate exposure to the hazard. Thus, personal protective equipment should not be regarded as a primary means to control hazards but rather as a supplement to other types of control measure. Injury will occur if hazards come into contact with our body, the degree of injury are depends on the magnititute of hazards and susceptibility of person. Protective clothing, gloves, apron, goggles and shoes – design to prevent absorption of chemical splash to the skin ? Safety helmet-to prevent from the sharp object falling on the head The effectiveness and efficiency of protection depends on proper use, maintenance and replacement of the PPE. If the PPE not used properly it can be more dangerous than not using as the worker would think that he is protected but in actual practice he is not protected. Factor to consider in the selection of PPE PPE should be carefully selected. The following criteria should be met when choosing PPE Give adequate protection against the specific hazard i. e right type and model ? Fit , minimum weight cause minimum discomfort and , if with attachment , it should be easily fitted and removed. ?Not restrict movement or sensory perception essential to the job ? Be easily worn and the eight to be supported by body ?Be durable and harmonious to the wear1`s culture and religion ? Not introduce additional hazards ?Be made to acceptable standards ?Be maintenance fee if possible, if maintenance is required , should be easily maintained ? Be replaced when necessary Used of respirators will prevent the entry of chemicals into the body by inhalation It is frequently used in industry where other forms of control are not practicable Type of respiratory protection : Are basically design to give protection against one or more of the following . †¢Contaminants in particulate forms †¢Contaminants in gaseous forms †¢Deficiency of oxygen With Full face mask or Half face mask Powered air is drawn through by a fan Non powered – air is drawn through by wearer inhalation Particulate filter come in various classes depending on their filtering efficiency. Gas filters are available for specific gases (e. g organic vapours, hydrogen, cyanide) Supplied air respirators (SARS) ?The air is supplied is not pressurized. It can be supplied by use of a fan , compressed air source or wearer inhalation. . ?The air supplied is pressurized and comes from a compressor or gas cylinder via an air line . Pressure is reduced prior to entering the respirator. ?The air is supplied from cylinders strapped to the wearer`s back Suppliers air respirators can have a negative pressure inside the face piece or a positive pressure. The positive types give a significantly higher evel of protection . Continuous flow types are also available for use with hoods. Protection factors This is a measure of the level of protection given by a respirator is defined as the ratio between the concentration of contaminant outside the respirator and the concentration inside the respirator(i. e the air breathed) Protection factor = ambient air concentration Concentration inhaled inside respirator For air purifying respirator it depends on the type of face mask and the efficiency of the filter. A full mask provide a higher level of protection than a half mask. For supplied air respirator it depends on pressure inside the mask(as well as the type of mask) . The protection factor is a major consideration when selecting a respirator. Selection of respirators; depends on:- †¢The contaminant †¢Task †¢Operator The contaminant i. The nature ,toxicity, physical form and concentration the contaminant, whether : particulate gas vapour or combination of both ii. whether failure of the device can result in a situation which is immediately dangerous to life and health. iii. The need to wear other personal protective equipment eg. Eye or skin protection to protect against irritants. iv. The adequacy of warning given by the contaminant v. The possibility of the contaminated atmosphere being flammable. Task. i. whether the device is for regular use for emergency or rescue purposes. ii. The probable length of time during which the wearer will be in the contaminated atmosphere. iii. The expected level of activity and mobility required of the wearer. iv. The access to and nature of the working environment and its location with respect to a source of air suitable for breathing. v. Vision and communication requirements. vi. Maintenance requirement. Operator factor †¢Basic physiology †¢Facial fit †¢User acceptance Fit testing is an important part of the selection process, particularly when the respirator design relies on a good seal. A range of respirators may need to be tried to fit individuals with different facial characteristics. Facial air can also reduce the effectiveness of seal significantly. Recognised test methods are available for initial fit testing. These are to design to detect or measure the amount of leakage around the seal of the respirator. Fit testing must be carried out when first issuing a respirator to a worker. Crude test (such as covering the openings and taking a vigorous breath) can be used in the field to check fit. Maintenance and storage All respirator (other than disposable types) need cleaning , maintenance and storage. Inhalation and exhalation valves need checking and replacement as do straps. Seals need to be disinfected , cleaned and check for damage.

The causes and effects of the stock crashes Essay -- essays papers

The causes and effects of the stock crashes Almost 75 years and almost 20 years ago, there were huge crashes in New York. These crashes caused an uproar throughout the nation. Number of people died, billions of dollars lost and damaged lots of lives. Those crashes had been called most severe of the 20th century. Those crashes are symbolized as Black Days. Well, you might think that those crashes could be car crashes or plane crashes or train crashes. You might also think that if nation could have lost billions of dollars and lots of lives, those could be car or plane or train crashes. But as you thought, those were not car or plane or train crashes 75 and 20 years ago. The reasons were different than what you are thinking. The main reasons to lost billions of dollars, lost precious lives and lots of damages to the nation were the Stock Market Crashes. On Thursday October 24, 1929 and on Monday October 19, 1987, there was a crash of stock prices on New York stock Exchange. It was a huge crash of stock prices in a single day. Billions of dollars and a number of precious lives were lost. But what we particularly think about Stock Crashes and how does it affect to common lives. The stock markets crashes and its affects are interrelated. The term stock crash came in to English Dictionary around 200 years ago. There was a first stock market crash in the history of economy and in early industrialization era, in the year 1878. It occurred in Wall Street and followed by huge opposition of stock system. But, if we define stock crash, it is a devaluation of stocks or shares of different industries since their price on the vary day. The devaluation of stocks may goes down from 1% to 50 %. It depends on the time and the parameters. And also we need to know what is the stock market. The Stock Market is a place of commerce where people can come and buy or sell parts of companies called "stocks" or "shares". For example, if you wanted to buy 30 shares of "Hevini Enterprise’s stock for $5.00 a share, you spend $150.00. Then you sell 20 shares to your friend Joe at $20.00 a share. That means that you make a net income of $250. This is the reason that the Stock Market is so popular with investors. This is how investors make their money. A stock is a certificate of a share of ownership in a business corporation, entitling it's owner to dividends, that i... ...before. People jumped from buildings to death. That was the Great Depression. World wide economic crisis has been raised following the New York Stock market crash in 1929. The stock market crash symbolizes the superficiality and greed of industrialization. It is caused by the thousands of people and it does affect millions of people. The crash teaches people to stop taking great risks and living carefree lives and be more responsible. The crashes break the nerves of economy and the nation. Following crash nation may lose all its economical growth and financial stability. So, Stock market crash is as danger as one might not think. Crash can be deadly like other disaster. It damages economy, thousands of lives and the it does affect psychologically. Bibliography: Works Cited â€Å"Analytical essay on the 1920’s† , January 21, 2000.

Local and National Provision for Hockey Essay

Sport’s a big part of today’s society, with hockey featuring highly. This is mainly due to the popularity of the sport within secondary schools and the national curriculum. With about 1150 hockey clubs in England, a National Governing Body (NGB) essentially organises the country’s hockey. England Hockey replaced the England Hockey Association (2002). It coordinates involvement and development with nationally run competitions and leagues. Much work’s also pumped into developing the foundations for future hockey: the young players of today. With high profile names involved in local schemes such as ‘Slazenger Stick Skills’, youngsters are encouraged to participate with rewards e.g. badges and certificates. The National Lottery helps develop all levels of hockey with funding via Sport England. It’s also in conjunction with the Youth Sports Trust and the Central Council for Physical Recreation. Through funding, Regional schemes such as Active Sports Talent Camps exist to develop the regions county and talented players. Lucazade often get involved with these local to territorial ‘stepping stones’. Locally, clubs such as Bradford and Halifax Hockey Club also exist and have junior teams to involve younger, future players. Local area teams like Calderdale compete against others, such as Wakefield, in developmental tournaments such as the Millennium Youth Games. This type of basic introductory competition promotes basic principals of hockey: fun whilst gaining experience and skill. Clubs receive private sponsors to fund kit, but main funding comes from the players i.e. hiring the pitch is paid for by subs. Some clubs may organise fund raising events such as ‘bag-packs’ at supermarkets. Sponsorship at national level is more serious with England Hockey leading the way in developing its image with investors such as Harrods and high status associations such as Great Britain Olympic Hockey and World Class Hockey. Hockey’s usually introduced at secondary school as part of the National PE Curriculum, but younger players may be introduced to junior sections of clubs through siblings etc. As a traditional sport that’s stereotyped for females (especially school level) private schools emphasise its’ importance by being in conjunction with local clubs to provide pathways for progression e.g. Bradford Girls Grammar School and Bradford Hockey Club. By regular club training and competition, a player may develop and be entered for local schemes/trials e.g. representing Kirklees in the West Yorkshire Youth Games. This can lead to scouting for county trials. Through higher standards of training and competition, development may continue and progression to a territorial level e.g. North England. Opportunities through trials and training weekends are provided and thus, following the pattern, international trials and competition. As seen by the diagram the different stages become more demanding with less players meeting the higher standards and progressing upwards. There’s ranging competition at all levels e.g. school- u12, to u18 and clubs varying from u11 up to numerous open age teams. Currently in England hockey is not a professional and therefore technically paid sport as it is in various other countries such as Holland. There is no provision for this level but with an increase of water based pitches and the senior men’s and women’s English hockey Leagues’ continuously improving standards of competition, the international scene is well established and provided for. By playing in the Senior National League a player has reached the top level of competition before international level, and thus it often leads to opportunities to trials for these highly developed players. There are however both male and female international competitions via club tournaments, and representative events for the England teams such as the Olympics, World and European Championships. Aside from the other agencies mentioned in connection with England Hockey the school link programme PESSCL partner the NGB to re-enforce participation in the education zone. They work together to implement it within secondary schools, but as yet there is no such scheme for primary schools such as ‘High 5 Netball’. This information is generally based on female participants but many clubs have male teams that are involved in national, regional and sub divisions. E.g. Sheffield has long standing, devoted men’s teams. Equality exists with popular, yet more social as most players are initially committed to gender specific teams. However colleges such as Greenhead provide for mixed team players and participate in regular competition. Although more profiled as a ‘female sport’ the National Men’s league has a higher status through more media and sponsorship coverage than the women’s league with early sponsors like ‘à ¯Ã‚ ¿Ã‚ ½ Stretcher and much more consistent media coverage from Sky Sports.’ Although sparse, Zone Hockey is a full flowing scheme that provides access to hockey for the disabled. It can be played on an equal level with able bodied players and is simply and adapted version of the original. It was developed between Nottingham Trent University, the Youth Sport Trust and England Hockey. It’s widely supported by associations such as the British Wheelchair Sports Foundation. A 5-a-side game that is fully adaptable to different playing surfaces and wheelchairs, that provides all boys and girls with a high scoring, fast moving, fun game. However there is no involvement at an elite level such as at the Paralympics due to its sparse global popularity and no record of an international English representative side Evaluating the situation of Hockey within England, it’s fair to say there’s a solid structure that can still be built on. Equality exists within the sport to the extent of mixed teams, of which most major sports in England do not provide for at senior level e.g. soccer. Also disabled access exists and is strong in many parts of the country but not to the extent of international competition. However, without professionalism, Hockey lacks funding that marketing, TV coverage rights, ticket sales etc. could provide. Fantastic facilities become ever more prominent (e.g. water based pitches), there is surely a gap waiting to be filled that would provide more access and opportunity locally and nationally including disabled athletes. This is certainly an aspect to consider for improvement and standard of the sport for all.

Jane Austens Influence on Literature Pride and Prejudice

Even though today Jane Austen is regarded for her writing, during her time she couldn’t even publish her work under her own name, because it was considered unladylike for women to be intellectual figures. Unlike J. K. Rowling and other English female writers today, who are well known for their works even without using their full names, Jane Austen lived within the sanctuary of a close-knit family and always published her works under a pseudonym that could not be traced back to her (jasna.org).

In her earlier works that were small pieces Austen worked on during her childhood, she exposed false literature and attacked sentimental novels. In all of her other works, Austen refused to write about the unusual or what she did not know. Instead, Austen forced herself to create plots dealing with ordinary, daily life (Pinion 135).
