EML 4314C -- Electrical Safety at a Glance Electrocution (death by electric shock) is the leading cause of death in research and development facilities. Several reasons for this: The use of electrical energy is widespread in modern technology. Survival of mild shock is dangerously misleading. A benign exposure to electrical shock is not indicative of future survival. Electricity is invisible. Unlike steam or noxious vapors, electrical hazards are not foreshadowed by precursor signs. Electric shock is the passage of current (from very high to imperceptible) through some part of the human body. The physiological effects of electric shock are: burns – damage to the skin by excessive heat (Joule heating) fibrillation – failure of the heart to contract regularly resulting in irregular beating and loss of efficient blood flow “let-go current” – level of electrical current at which a person can release a live wire of his own free will, above which the current causes involuntary muscle contraction
