Abstract The subject of electrical hazards analysis has been recognized by a small segment of the electrical industry for many years. The petrochemical industry and many government institutions have performed research on this subject for over twenty years. For the most part however, the electrical industry, at least at the user level, has largely ignored the subject, essentially reacting to catastrophic accidents, rather than proactively trying to predict and prevent them. Recent changes in consensus standards, along with a better general understanding of the seriousness of electrical hazards have resulted in a renewal of interest in the subject. As the awareness of electrical hazards increase many are puzzled by phrases like; “Limited”, “Restricted”, and “Prohibited Approach Boundary”, and “Flash Protection Boundary”. Understanding these terms is important to understanding shock and arc-flash hazard protection. NFPA 70E-2004, Standard for Electrical Safety in the Workplace requires that an electrical hazards analysis be performed prior to working on or near exposed energized electrical conductors and circuit part operating at 50-volts or more. This is…...

...Working Near Overhead Power Lines Many occupations may require workers to perform their job tasks near overhead power lines. Construction workers, truck drivers, tree service workers, mobile equipment operators, agricultural workers, and others find themselves carrying-out their work in the vicinity of energized overhead power transmission lines. They may not be trained to recognize the dangers of electrocution if their bodies, equipment, tools, work materials, or vehicles come near to an overhead line. Electrical utility workers are generally highly trained to recognize and manage electrical hazards – other workers are less so. Most high voltage electrocutions in Washington State do not involve power line workers. Both national and Washington State data show a high number of fatalities for workers in construction, tree trimming, agriculture, and others who frequently work near overhead power lines. The following information is primarily intended for workers other than electrical utility employees but may benefit anyone working around power lines. Working Near Overhead Power Lines: Stay Away! Stay Alive! These are brief case descriptions of selected fatalities that happened during work near energized overhead power lines in Washington State during the years 1998-2005: Case1 On August 19, 1998, a painter moving a 32-foot aluminum extension ladder received a fatal electric shock when the ladder contacted one phase of a 3-phase system of 13,200 volts.

...Safety Slogans Here are some safety slogans that will help you to make safety a way of life. [pic] Safety is a very important aspect of life, be it at home, out on the road, or at the workplace. Here is a collection of some great safety slogans that you can use on posters to stick up in your office or in your home, or use in presentations, or send as emails. Safety isn't just a slogan, it's a way of life. Better to be safe than to be sorry! Chance takers are accident makers. Be alert! Accidents hurt. A safer you is a safer me. Unprepared = Unsafe. Anyone driving slower than you is an idiot, and anyone going faster than you is a maniac. The best car safety device is a rear-view mirror with a cop in it. Remember - Safety is not a job; it is a way of life. Safety is a cheap and effective insurance policy While on a ladder, never step back to admire your work Safety doesn't slow the job down but mishaps do. A spill, a slip, a hospital trip. Your safety is everyone's responsibility, especially yours. You can't get home, unless you're safe. Ignoring a warning can cause much mourning. The adage "look before you leap" is a lifesaver. The safe way is the right way When jogging, run against the traffic flow. Wear the right protective equipment for the job. Use the right tool for the job. Just because you always did it that way, doesn't make it right. Safety is something you learn from the start - Being accident......

... including tools and equipment which may be furnished by employees. All hazards involved in the use of power tools can be prevented by following five basic safety rules: • Keep all tools in good condition with regular maintenance. • Use the right tool for the job. • Examine each tool for damage before use. • Operate according to the manufacturer's instructions. • Provide and use the proper protective equipment. Note the following key points in this lesson: • Hazardous moving parts of a power tool need to be safeguarded. • All employers should caution employees that saw blades, knives, or other tools be directed away from aisle areas and other employees working in close proximity. • To protect the user from shock, tools must either have a three-wire cord with ground and be grounded, be double insulated or be powered by a lowvoltage isolation transformer. • Portable electric powered tools must meet the OSHA electrical requirements. • All jacks - lever and ratchet jacks, screw jacks and hydraulic jacks - must have a device that stops them from jacking up too high. Remember: Employees should be trained in the use of all tools - not just power tools. They should understand the potential hazards as well as the safety precautions to prevent those hazards from occurring. Appropriate personal  protective equipment, e.g.,  safety goggles, gloves, etc.,  should be worn due to hazards  that may be encountered while  using portable power tools and  hand tools.   ...

...ELECTRICAL SAFETY Safety in the workplace is job number one for employer and employee. It is especially important for those who install and service electrical system. Electrical safety defines as “Recognizing hazards associated with the use of electrical energy and taking precautions so that hazards do not produce injury or death”. Nothing can replace a worker or loved one that has died or suffered their reparable consequences of an electrical accident. Government statistics shows that electricity cause more than 20,000 fire a year, almost half of all accidental UK house fire. Each year, about 70 people are killed and 350,000 are seriously injured due to an electrical accident in the UK. Modern living has meant we use more and more electrical appliances in the home. For instance, just 20 years ago the average uk home had a hi-fi system and one TV whereas today it is more likely that there are at least two TVs, games console, microwave and computer.so that risk of electricity accidents in the homes are more higher than before. It has seen in the UK that there are lots of people drying their cloths on electrical heater. This is particularly dangerous and could cause electric shock or fire. Heater have ventilation slots to prevent overheating. If this slots are covered up, the appliance could over heat and catch fire. Many time people are drilling the wall to fix nail without knowing......

...CHAPTER 16: SAFETY Based on past studies, the water and wastewater industry has one if the highest injury rates in the nation. Workers in these areas are involved in construction and excavations, confined spaces, hazardous chemicals, and mechanical equipment that pose a serious injury risk when proper training, equipment, and procedures are not utilized. The Occupational Safety and Health Administration (OSHA) is responsible for developing regulations regarding worker safety and protection. Employers are responsible for providing employees with the proper safety equipment and training in its use. They are also responsible for development and implementation of safety policies for their workplace. The employees, after proper training, are responsible for recognizing the safety issues; following approved safety procedures, and properly utilizing the associated safety equipment. Lock Out/Tag Out (LOTO) Lock out/tag out regulations deal with the need to isolate a machine from its energy source to prevent it from starting while work is being done in and around the equipment. Energy sources can include electrical energy, hydraulic energy, pneumatic energy, thermal energy, and chemical energy. This can be either active energy or stored energy. Stored energy can take many forms. Some examples of stored energy are; electrical energy stored in capacitors, pneumatic energy stored in a compressor tank, and hydraulic water pressure in an isolated line. Any stored energy must...

Electrical Design

...Electrical services design Institution Student name Introduction The need for electricity has been ever increasing. As well, the numbers of critical or sensitive loads have also increased. Today, the electricity transmission and distribution is greatly affected by this ever growing need. On the other hand, the consumer's demand has also been in a rising manner. These problems can be catered for by the use of energy storage devices, renewable energy and use of distributed generation. Micro-grid paradigm can deal effectively with the ever increasing electricity needs. This paradigm is bestowed with the ability to regulate the electricity flow. This is achieved through the generation and distribution mechanisms. Grid refers to different interconnection of different electricity transmission lines. The line does not necessarily need to be transmitting electricity of equal magnitudes. But the electricity of different magnitude that runs from the highest to the lowest magnitude possible. In short, the grid connects the consumers to the electricity supply utilities (Vittal & Ayyanar, 2013, pg. 162). The renewable energy integration into the main grid can take place in the distribution or at the transmission levels. The point at which integration takes place depends on the size or the scale of the electricity generation. Large generating stations directly feed the main grid. Unlike large generating stations, the small distributed generations feed the low or medium voltage......

Safety Awareness in Electrical Engineering

...Safety Awareness in Electrical Engineering It is important for students studying to become electrical engineers to be aware of electrical safety measures and hazards. There are several severe, even life-threatening hazards that one could encounter when among electrical equipment. Two main dangers related to dealing with electrical equipment shocks and burns are overloading outlets with too many devices, and neglecting to implement the usage of a Ground-Fault Circuit Interrupter. While outlets are designed to handle multiple plugs, it is crucial to know that they do have limitations as far as what they are capable of supporting. Various dangers can occur by overloading an outlet. Risks of electrical fires are increased when two or more appliances are plugged in at once, or when extra electricity is required by means of an extension cord. This is also the reason why major appliances such as refrigerators and dryers should be plugged directly into their own outlet; they are heavy power users. Although most homes and appliances have fuses as a form of safety to prevent fires, people should still be aware of the amount of power can be placed on each outlet or circuit. A safety procedure that could potentially be life-saving is the usage of a ground-fault circuit interrupter (GFCI). It protects people from electrical shocks by monitoring the amount of current flowing in a circuit (from hot to neutral), and thereby locating a loss of current. If it senses an imbalance, the...
