Arcing is current leaving a conductor and traveling through a gas (usually air) to another conductor or ground path. This can result in intense light and heat to be released as the molecules in the air are superheated. This is referred to as arc flash electrocution electric shock flash burn 2 points is the total volume of electrons moving (like water flowing) past a certain point, in a given length of time. current voltage resistance electrical frequency 2 points All metal objects have a natural electrical charge. When two metal objects are brought together, they will attempt to equalize, and it is possible that an electrical spark would result. is the joining of metallic parts to establish an equal electrical charge. bonding current grounding short-circuiting How is the severity of electric shock determined? the amount of current that flows through the victim the length of time that the tissue is exposed to the current the path and body parts affected as the current travels through the victim All of the above 2 points It is estimated that 50mA(AC) is sufficient to cause which is a problem that occurs when the heart beats with rapid, erratic electrical impulses. This causes the pumping chambers of the heart (the ventricles) to quiver uselessly, instead of circulating blood. The heart cannot spontaneously recover from this condition, and survival depends on effective rescue efforts. Ventricular fibrillation Heart attack Electrocution Arc flash/arc blast 2 points The sooner a victim of electrical shock is resuscitated, the better the chances of survival. Immediate application of an AED and/or CPR to a victim increases the likelihood of survival. For every of delayed treatment, the victim's chance of survival is decreased by 7% to 10%. minute second hour day
