Abstract
A person’s understanding of a safety hazard has a dramatic effect on his or her behavior. An in-depth understanding of a hazard usually results in a healthy respect for what can happen. People who know the most about a specific hazard tend to rely more heavily on procedures and plans to guide their actions. Personal protective equipment selection and use are influenced by increased understanding of a hazard. Training and training programs are influenced by the depth of knowledge held by all members of the line organization. Recent work has focused attention on the thermal effects of arc flashes. However, when electrical energy is converted into thermal energy in an arcing fault, still another energy conversion is taking place. Applications are on record that suggest that a considerable amount of force is created during an arcing fault. Concrete block walls can be destroyed by the increased pressure that is created during an arcing fault. This study is present about preventing injuries to people. We will study about injuries and then develop some understanding about electrical hazards. Also, we will present about safe work practices, responsible, and then about what makes us act as we do.
Highlights
Electricity hazards have been well documented through the years and various papers, guides and books have been published that focus on such hazards, the reasons, analysis, prevention measures etc in various applications [1-65]
Since most arc-flash burns are recorded just as burns, some estimates suggest that 80 percent of all injuries from an electrical hazard is the result of an arc
Arc Flash: When an arc-flash event happens, pressure that is created by the superheated air and vaporizing metal expels droplets of molten metal and other parts and pieces with great force
Summary
Electricity hazards have been well documented through the years and various papers, guides and books have been published that focus on such hazards, the reasons, analysis, prevention measures etc in various applications [1-65]. Since most arc-flash burns are recorded just as burns, some estimates suggest that 80 percent of all injuries from an electrical hazard is the result of an arc. Insufficient information is available to suggest that one method provides more accurate information than another National Electrical Codes usually require a label on equipment where potential for an arc-flash injury exists. If the source of energy is removed with assurance that it cannot reaccumulate, all exposure to an electrical hazard has been removed. This practice should always be the first option. The first generally recognized hazard associated with electrical energy was fire These conditions frequently result in a fire. Electrical injuries would be the largest category
