Shock Meaning is when an electric current passes through the body. This almost always causes damage to the tissues and may result in severe and sometimes fatal injuries.
To protect from Electric shock, Stay well-insulated and use a non-conductive material such as wood if you try to push the casualty away from the source of the current.
What Are Electrical Accidents Or Shock Meaning?
The current can come from a low or high voltage supply, or even lightning, which is a natural source of electricity.
How dangerous an electrical injury depends on three things: how good the connection is from the victim to the earth; what route the electricity takes through the body; and how long the current flows through the body.
On the other hand, the risk of injury is decreased if the environment is dry or, for example, rubber-soled shoes are being worn.
About 30 people die each year at home from electrical injuries, many as a result of faulty switches, frayed cables or defects within electrical appliances.
Many other electrical accidents and deaths occur in the workplace. About ten people die each year from being struck by lightning. Contact with high voltage electricity is usually immediately fatal.
Symptoms & Signs Of Electric Shock
In most cases, the casualty will be unconscious, even if the current was small. Also, the casualty may have:
|Shallow, rapid breathing, with snoring sounds.|
|A gray or ashen face.|
|Absent heartbeat, lack of breathing.|
|Deep contact burns where the current entered and left the body.|
|Signs of shock, including clammy skin, weak and rapid pulse.|
What damage can electrical accidents do?
Electrical accidents shock can cause considerable damage. An electric current running through the body can disturb the heartbeat or cause a quivering of the heart muscle, called fibrillation. A high current may cause the heart to stop beating altogether.
Breaking the current
The most important step is to break the electrical contact. To cut a low voltage current, switch off the current at the mains or meter if you can.
If not, pull out the plug or tug the cable free: If you cannot reach the plug or cable, protect yourself by standing on dry insulating material
such as a wooden box, or rubber or plastic mat, and use a tool such as a broom handle or chair leg to push the casualty away from the source of the current.
Do not use anything metallic or damp and do not touch the casualty with your hands. Do not attempt first aid until the electrical contact has been broken.
If the casualty is unconscious, the priority is to ensure he or she has a clear airway, is breathing and has a heartbeat. If so, then treat any burns.
First aid for an unconscious casualty
Open the airway by placing two fingers under the chin and lifting the jaw. At the same time, put your other hand on the forehead and tilt the casualty’s head back.
Check for breathing and pulse.
Resuscitate as necessary:
If there is no breathing or pulse then carry out CPR (cardio-pulmonary resuscitation).
If there is a pulse, give ten breaths of artificial ventilation, Continue to provide artificial ventilation until help arrives.
If the casualty is breathing and there is a pulse, assess the person’s level of response by shouting next to his or her ear and pinching the skin.
Cool, any burns with cold water. Remove any jewelry or constricting clothing from the injured area before it starts to swell.
Check breathing and pulse regularly and be prepared to administer artificial ventilation and or CPR.
First Aid For A Conscious Casualty Shock
Treat any burns by dousing, or immersing the injured part in cold water, for at least 10 minutes or longer until the pain has eased. Apply cling film or a non-fluffy dressing to protect burns on the limbs or torso, but do not apply dressings to facial injuries. Do not break any blisters that form, or use any lotions or creams.
|First Aid For A Clinical Shock|
|Lay the casualty down, with head low, and legs raised and supported.|
|Loosen any tight clothing and keep the casualty warm with coats or blankets. (Do not use external heat, such as a hot water bottle or electric fire).|
|If the casualty becomes unconscious, place in the recovery position, and check breathing and pulse regularly.|
|Be prepared to administer artificial ventilation and or CPR if necessary.|
