Electricity can be dangerous if careful precautions are not taken. Deaths and injuries can arise if electrical equipment is not properly maintained, if unsuitable electrical equipment is used in explosive areas such as paint booths, or because of fires that are started from faulty equipment. In addition, work near overhead power lines or underground cable lines during excavation work carry additional dangers.
Electricians, as well as others who work around electricity in the workplace or at home, should always be vigilent as to the possible dangers of electricity. When assessing a situation, always first identify the potential hazard, identify who might be harmed and in what fashion, and then determine and implement the necessary precautions.
Some of the primary hazards that are related to electricity include either direct or indirect shock, burns, arc-blasts, explosions, and fires. While mild shocks may only produce tingling and muscle contractions, heavy electrical current flow can result in severe burns, heart paralysis or death. In order to prevent the danger of electrical shock, anyone working with electricity should carefully observe proper grounding techniques and precautions. This is equally important for the general public as well as electricians.
Those who work with electricity on a regular basis, such as electricians do, have special health and safety concerns. When working with electrical systems, especially in certain types of environments and surroundings, the electrician may be exposed to materials such as solder, lead, solvents and other types of potentially hazardous materials. There is also of course a constant risk or electrical shock or burns, as well as other hazards such as UV radiation. Electricians may routinely encounter extreme temperatures, dangers from power and hand tools, and the need to work in confined spaces or at high elevations. They also need to be constantly vigilant against the risk of possible eye injuries from flying objects, slips or falls, or injury due to heavy lifting, repetitive manual activities, and awkward positions.
Electricians, as well as anybody else who is around electricity, can employ preventative measures to reduce the risk of injury. These include keeping all equipment and tools in good repair and working order and being sure to wear the correct personal protective equipment, including protective footwear. Work areas should always be kept free of equipment and other types of clutter, and care should be taken with all power lines or cords. Additionally, safe lifting techniques should always be used, and frequent breaks should be taken to avoid the stress of repetitive tasks and working positions.
Good general work safety practices include always following the correct electrical safety procedures, as well as using good lock-out/tag-out processes. Care should always be taken when working at heights or in confined spaces, and all tools and personal protective equipment should be kept in good repair, and should be maintained and stored according to the manufacturer's specifications. There should be an awareness of any relevant MSDS or WHMIS information, as well any possible chemical hazards. Anybody working around electricity should be knowledgeable as to how to report a hazard or emergency situation, and should follow all safety rules and regulations.
