Task heart from beating and cause a

Task 1cElectric shocks happen when a person gets in contact with highvoltage. The effect electric shocks have on people can be harmful for instant, ifa person was electrocuted with a very high voltage then it could cause death becausethe rhythm of the heart would be disturbed or in some cases the current canstop the heart from beating and cause a cardiovascular arrest. Electricalshocks can cause burns. If the voltage was not too high, then burns can befound just on top of the skin. But if a high voltage was to shock a person thenit could cause internal burns. Such as burns to the organs that can affect theheart.

The burns which are caused by electric shocks can cause organ failurewhich results in death and if a person was to survive then recovery would belong and painful. Moreover, neurological effect is another factor which can beharmful to the human body. This is when electric shocks disturb the nervouscontrol effecting on heart and lungs. When electric shocks disturb the nervous system,it doesn’t in most cases leads to death but can make a person be unconscious. Italso, effects the chest when 50 or 60 Hz is passed through the chest. Itresults in ventricular fibrillation. This must be treated as soon as possibleas it can cause the heart muscle to beat fast and loose its normal rhyme. Iftoo much is passed through the chest then it can stop the heart from beating assoon as it has travelled to the chest.

The following are the most common effects of electricshocks:·        A person has high chances of collapsing ·        A person would have high chances of musclecontractions that can cause fractures and loss of consciousness and in somecases, it can cause the joins to dislocate ·        A person could have a paralyze to therespiratory system and can change the rhythm of the heart or can stop it frombeating completely. Tissue that are at the start and end of the current candie.·        A persons blood pressure can drop which causesthe electrolyte balance to release myoglobin resulting in kidney failure. Fires are mostly started in mains wires (homes, buildings)or due to manufacture failure. Damaged outlets, equipment start fires and old outdatedapparatus.

Others can be started by problems in cords, receptacles andswitches. Cords that have been damaged should not be near floors, curtains andrugs as it is most likely can start off fires. And cords under rugs can causefires which can be dangerous. Most the fires are started by people who do notfollow the instructions of an electrical equipment. Extension leads can causefire and portable heaters also start fires. The impact that fires have onhumans is that it can cause severe burns which can cause the skin of thesurface to burn and internal burns can be caused. This causes the body tissuesto be scarred which means dead is most likely to occur and then the fibroustissues are instead replaced with the dead tissue.

Dc and Ac:   Ac and dc both are harmful to the body, but the symptoms areslightly different depending on the voltage if it is high then there is morerisk than it is low. It also, effects on the amount of current, time of flowand pathway current. It is said to be that ac current is more harmful to ahuman than dc because more dc currents are needed to make the same harmfuleffect that ac current would have. This is because more milliamps are requiredin DC as it is a flow of current in one direction so if a person was to get anelectric shock from the hand or feet then it wouldn’t be so bad as it doesn’t crossthe heart, but still the person would have a lot of internal burns which couldlead to death. With AC it’s not as simple as the current flows in alldirections so when a person is electrocuted with AC current then it is mostlikely the current has been to the heart which can stop the heart from workingand lead to death.

The series of contraction is dependent on the amount offrequency that is applied to the human body. Also, more milliamps are requiredfrom DC current then AC even if it is the same voltage.
