Electrical Hazards Electrical Hazards, risks of injury or death arising from exposure to
electricity. Electricity is essential to daily life, providing heat
and light and powering appliances in homes and factories. It must,
however, be treated with great care, because the consequences of an
electrical fault can be serious and sometimes fatal. Generally
voltages greater than 50 volts can present a serious hazard and
currents of more than about 50 milliamps flowing through the human
body can lead to death by electrocution.
A shock occurs when a "live" part of some device is touched, so that
current passes through the body. Its severity depends on many factors,
including the body's conductivity (the ease with which electricity
passes through it). The conductivity is usually small, but can be
increased if the body or clothing is wet. The risk of injury also
increases according to the size of the voltage or current, or the
duration of contact. There is a risk of electrocution (death by
electric shock) if current passes across the heart. For example, if
one foot is touching wet ground, the risk is greater if the arm on the
opposite side touches a high-voltage source than it would be if the
arm on the same side did so.
Current passing into the body generates heat, which burns the tissue.
Electricity can also present less direct risks. Burns are caused when
hot surfaces on electrical appliances are touched, and some appliances
present a risk of injury from moving parts. Fires are caused when
wires or cables overheat, melting their covering of...

sub-stations, and factories, and fishing-rods, especially those made
of carbon fibre, and kites must not be used near overhead power lines.
Anyone using electrical equipment out of doors should ensure that the
supply is protected by an RCD (residual current device), which detects
any current to earth and so will protect the user against the danger
of serious electric shock by disconnecting the supply in the event of
a fault occurring.
In the home, fuses, which are a rather crude method of protecting the
distribution system against excessive current, have largely been
replaced by the more precise MCB (miniature circuit-breaker), and RCDs
are now usually incorporated to provide added safety from the danger
of electric shock.

There are a few types of medical errors discussed in Patient Safety Principles & Practice. One of them is an error of execution. An error of execution is when a correct action does not proceed as intended. It is a failure of a planned action to be completed as first intended. It occurs unintentionally during an automatic performance of patient care. This error is almost always observable at the patient and caregiver interface.
Safety is a primary concern in the health care environment, but there are still many preventable errors that occur. In fact, a study from ProPublica in 2013 found that between 210,000 and 440,000 patients each year suffer preventable harm in the hospital (Allen, 2013). Safety in the healthcare environment is not only keeping the patient safe, but also the employee. If a nurse does not follow procedure, they could bring harm to themselves, the patient, or both. Although it seems like such a simple topic with a simple solution, there are several components to what safety really entails. Health care professionals must always be cautious to prevent any mishaps to their patients, especially when using machines or lifting objects, as it has a higher
What is Radiation? Radiation is a A form of energy carried by waves or a stream of particles. Radiation is a fragment that is capable of ionizing atoms or molecules isolating electrons from them due to its sufficiently possessed energy when it is passed through them. Radiations include alpha, beta and gamma rays. They can cause severe damage when absorbed by living tissue, and are therefore a health hazard they can effect the repairing ability of living cells. Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach

Food hazards can be generally defined as a state or pollutant that may have the potential to cause disease. The issues of food hazards have become widely recognized internationally in the last decade. With modern technology, scientists have been able to identify foodborne diseases prompted by food hazards on a global scale and have acknowledged these hazards as a primary cause of morbidity (Friis, 2012). I chose to focus on food hazards, their significance, and their effect on a global scale because this is an issue that most people have, at some point, encountered throughout life. In my own life, I’ve experienced mild illness as a result of food that had been exposed to harmful bacteria, and have known individuals who faced more serious health
Within the Care Industry the Occupational Safety and Health Administration (2010) stated that “nursing aides, orderlies and attendants had the highest rate of musculoskeletal disorders of all occupations in 2010”.
Hazardous materials can be important in everyday life when properly handled. However, when improperly handled, they can result in injury, death, and destruction as well as have lingering effects that may last for years to come. To address the risk of an uncontrolled hazardous materials release, there must be a coordinated effort to identify, locate, and quantify the hazardous materials in a particular location (Drexel University Safety & Health, 2001). Typically, industry and government agree that a hazardous materials incident is one where
Keeping patients safe is essential in today’s health care system, but patient safety events that violate that safety are increasing each year. It was only recently, that the focus on patient safety was reinforced by a report prepared by Institute of medicine (IOM) entitled ” To err is human, building a safer health system”(Wakefield & Iliffe,2002).This report found that approx-imately 44,000 to 98,000 deaths occur each year due to medical errors and that the majority was preventable. Deaths due to medical errors exceed deaths due to many other causes such as like HIV infections, breast cancer and even traffic accidents (Wakefield & Iliffe, 2002). After this IOM reports, President Clinton established quality interagency coordination task force with the help of government agencies. These government agencies are responsible for making health pol-icies regarding patient safety to which every HCO must follow (Schulman & Kim, 2000).

A hazard is defined as an activity or object that has the potential to cause harm if contact is made with the person, object or activity (MHS, 1996; Harmse, 2007; HSE, 2006). These hazards in a work place need to be identified and dealt with accordingly to prevent any harm to employees or any individual acquainted to a certain activity or establishment. The key roles and principles of occupational hygiene are Anticipation, Identification, Evaluation and Control (Schoeman and van den Heever, 2014; Harmse, 2008; SAMTRAC, 2012). To practise in accordance to the above principle; a hazard identification and risk assessment needs to be conducted. Anticipation is the foreseeing of the activity
The report I am going to write about is to do with electrical safety devices and safety practices which contribute in reducing and eliminate specific risks. The workplace I have chosen to write about is electricians in power stations. The report I am going to write is going to show a clear understanding of electrical safety devices and the improvements of electrical safety devices.
