risks of electricity

Introduction

WHAT ARE THE RISKS FROM ELECTRICITY? Harm can be caused to any person when they are exposed to 'live parts' that are either touched directly or indirectly by means of some conducting object or material. Voltages over 50 volts AC or 120 volts DC are considered hazardous. Electricity can kill. Each year about 1000 accidents at work involving electric shocks or burns are reported to the Health and Safety Executive (HSE). Around 30 of these are fatal, most of them arising from contact with overhead or underground power cables. WHO IS MOST AT RISK FROM ELECTRICITY? Anyone can be exposed to the dangers of electricity while at work and everyone should be made aware of the dangers. Most electrical accidents occur because individuals: * are working on or near equipment which is thought to be dead but which is, in fact, live * misuse equipment or use electrical equipment which they know to be faulty. ...read more.

Also, contact with live parts can cause shocks and burns. Fire Electrical faults can cause fires. This is particularly true where the equipment contains a heat source (e.g. heaters, including water heaters, washing machines, ovens, heat-seal packaging equipment). Flammable or explosive atmospheres Electricity can be a source of ignition in a potentially flammable or explosive atmosphere, e.g. in spray paint booths or around refuelling areas. WHERE AND HOW ELECTRICITY IS USED The risks from electricity are greatest in harsh conditions.In wet conditions, unsuitable equipment can easily become live and can make its surroundings live. While outdoors, equipment may not only become wet but may be at greater risk of damage. In cramped or confined spaces with a lot of earthed metalwork, such as inside tanks, ducts and silos, if an electrical fault develops it can be very difficult to avoid a shock. TYPES OF EQUIPMENT IN USE Some items of equipment can also involve greater risk than others. ...read more.

Conclusion

Reduce the voltage: Using lower voltages can reduce or eliminate the risks of electric shocks and burns:. Use Residual Current Devices (RCDs) for extra safety: An RCD can provide additional safety. An RCD detects some faults in the electrical system and rapidly switches off the supply. MAINTAINING ELECTRICAL EQUIPMENT AND INSTALLATIONS. If a fault is identified, the item should be removed from use and repaired before being used again. Staff should be trained to carry out these simple visual checks. There should also be a system where formal visual inspections are carried out the legislation requires employers to decide on the frequency of testing based on their risk assessment. WORK SAFELY Make sure that: * suspect or faulty equipment is taken out of use immediately * people working with electricity are competent to do the job. * suspect or faulty equipment is kept secure until examined by a competent person * tools and power socket-outlets are switched off before plugging in or unplugging * equipment is switched off and/or unplugged before cleaning or making adjustments * where possible, all electrical appliances are switched off at the mains at the end of the working day. ...read more.

Response to the question

The candidate gives a very in depth response, they have included the main risks and how these occur and have given safety information relating to the use of electricity. In addition to this they have clearly undergone independent research as they mention the legal obligations involved when dealing with electricity and they have provided information regarding the maintenance and insulation of electrical equipment. This is a good way to develop your essay and it shows a thorough understanding of the set topic.

Level of analysis

This piece of writing is in the form of an informative leaflet rather than an essay therefore the fact that there is no conclusion is irrelevant, that said the information provided is accurate and the candidate has given a great deal of detail. In addition to this, the candidate has sensibly included a link to the resources they have used when researching information for this piece of work. It is always a good idea to include references to any sources you have used.

Quality of writing

The candidate often uses bullet-points which is I feel is appropriate for this type of work as the candidate is listing safety features and specific legal obligations, sometimes important information is easier to see if listed this way than if it were in a standardised paragraph. Furthermore scientific terms are used accurately and there no errors with spelling punctuation or grammar.
