Electrical Safety 2101 Michael Dziak Walden University
MODULE 4ELECTRICAL SHOCK OBJECTIVE: • Identify administrative controls that electrical personal use to work safely and prevent electric shock
SHOCK HAZARDS • Electrical Shock occurs when the human body completes an electrical circuit and becomes the conductor • Electrical safety depends on qualified personal • NOT allowing their body to become the conductor • A good rule of thumb to heed is that electricity always • will follow the least path of resistance
SHOCK HAZARDS • Electrical Shock occurs when the human body completes an electrical circuit and becomes the conductor • This person is in danger because the switch is open and they have inadvertently become a conductor
SHOCK HAZARDS • Electrical Shock occurs when the human body completes an electrical circuit and becomes the conductor • This person is very sad because the switch is closed and they have inadvertently become a conductor
EFFECTS OF SHOCK • Severity of shock is related to amount of current and the path through the body • A current path through the heart is extremely dangerous since the human heart is controlled by small electrical signals from the brain • A very small current can cause cardiac arrest and the person has a great chance of death unless CPR can be administered immediately
EFFECTS OF SHOCK • Electrical current not passing through the heart can cause pain, paralysis, or tissue burn • Side effects of non fatal electrical shock are confusion, amnesia, headaches, and cardio-pulmonary irregularities • Health issues from electrical shock can last several hours, several days, or can lead to chronic health issues in certain cases
SHOCK TREATMENT • De-energize the circuit • Remove the victim from the circuit or dangerous area • Call 911 and a 1st Responder Team if one is available in your work site • Administer CPR if necessary
ARC FLASH HAZARDS • Arc Flash occurs when and energized source comes in close proximity with a grounded source creating an instantaneous blast or explosion • The potential effects are devastating to any human in close proximity to the arch flash causing severe burns and hearing damage • Arc Flash is preventable using explosion doors and proper protective equipment when qualified personal are required to work on energized equipment
QUIZ 4A • What is the correct sequence of events to follow if you observe someone receive a serious electrical shock? • Call 911, de-energize the circuit, go home • Call 911, give first aid as needed • Call 911, de-energize the circuit, remove victim, take victim for medical treatment, report the incident
QUIZ 4B • Electric Arc Flash occurs when: • An electrical system is over-loaded • An energized source comes in close proximity with a grounded source • When an person’s hand comes in contact with insulated energized conductors
QUIZ 4C • If you discover an unconscious person, clearly a victim of electric shock, and are unable to de-energize the electrical circuit, how do you remove the victim from the circuit? • Do nothing. There's nothing you can do to help him. • Grab the person, pull them off the energized line, render CPR. • Wait for EMS to arrive because they are trained to deal with this kind of problem • Use non-conductive dry wood or similar material to move him off the energized line, render CPR.
