Electrical hazards are not limited to electric shock; those who are not working with or using electricity may be also at risk. Faulty electrical appliance or equipment and poor electrical installations may lead to fire which could potentially injure people around it. According to National Fire Protection Association, approximately 2600 people are killed in home fires each year, most are caused by electrical faults [4]. Also, electricity or even static could be the source of ignition in a potentially flammable or explosive atmosphere. For example, in a garage where contain vaporized gasoline due to a tipped over gas tank, the static generated between the car door and key can cause explosion if the ratio between air vaporized gasoline is within the explosive range.
Electromagnetic interference is disturbance which can affect an electrical circuit with electromagnetic induction or radiation [6]. It’s a serious hazard especially for airlines. The modern aircrafts are heavily dependent on navigation and other vital electronic systems. Electromagnetic interference may cause these systems to malfunction and lead to crash. A researcher from Harvard University, Elaine Scarry stated that Electromagnetic interference in the airspace east of JFK airport may have caused three air crashes in 20th century; the crash of TWA Flight 800 in1996, the crash of Swissair Flight 111 in 1998, and crash of Egypt Air Flight 990 in 1999 [7].
