An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
A flexible electrical cord may be damaged by door or window edges, by staples and fastenings, by equipment rolling over it, or simply by aging. [20] The potential for possible electrocution or electric shock or contact with electrical hazards can result from a number of factors, including the following:
In addition, other hazards may also be present such as heat stress, slips trips and falls, struck-by injuries, toxic metals, toxic gases, electrical shock, lasers, shift work and fatigue. If multiple hazards are present in a work activity, the status of the hierarchy of controls can be assessed for each hazard, and a worst-first, all-hazards ...
Three elements are required for an electrocution to occur: (a) a charged electrical source, (b) a current pathway through the victim, (c) a ground. The health hazard of an electric current flowing through the body depends on the amount of current and the length of time for which it flows, not merely on the voltage. However, a high voltage is ...
Faulty electrical connections and damaged electrical equipment can lead to an electric shock to workers and to others at or near the workplace. [ 35 ] According to the Bureau of Labor Statistics , a total 1,738 accidents occurred due to contact with electric current between 2003 and 2010, and out of that, the highest number of electrical ...
Electrical shocks on humans can lead to permanent disabilities or death. Size, frequency and duration of the electrical current affect the damage. [8] The effects from electric shock can be: stopping the heart beating properly, preventing the person from breathing, causing muscle spasms. The skin features also affect the consequences of ...
Possible sources of macroshock include: poorly designed or malfunctioning electrophysiology equipment, lightning, damaged power cords or other electrical hazards around the household, downed power lines, high-voltage electrical equipment such as transformer stations and other industrial electrical equipment, and malfunctioning electrical or electricity-using mechanical equipment capable of ...
The standards are drawn up with a set of rules for protection from to limit human exposure to electric fields, magnetic fields and electromagnetic fields. Frequency bands of danger EMF, Zones of danger EMF, types of risks, safety and shielding equipment are categorized in the standards. Electrical safety analyser
