Sometimes it is difficult for wireman to detecting the existence of an unstable utility power through smell, sight, or sound, an electrical hazard can occur suddenly without warning when electricity is handled without proper guidance. Electricity’s inherent dangers include electric shock, burns, psychological and neurological damage, ventricular fibrillation, and ultimately death.
Risk Exposed for Wireman
Various cases of wireman improper handling for electricity have resulted in the most horrific indirect damages, such as explosions, fires, and falls. According to some experienced wireman & electrical contractor in Malaysia, the minimum current a human can feel is approximately 1 milliampere (mA), while at a slightly higher rate of 80 mA, electricity can seize the heart muscle, causing tissue damage or heart fibrillation. The effects of an electric shock vary depending on the voltage, duration, current, route, and frequency.
Electrical Shock Is Severe
To bring the severity of an electrical shock into perspective, 100 mA of electricity coursing through the human body for two seconds causes the arms and legs to freeze; prolonged exposure can cause respiratory paralysis and death.
High-voltage shocks transmit a great deal of energy, causing internal burns, and are extremely lethal if the electricity path crosses vital organs like the heart.
According to an experience Malaysian electrical contractor, a low voltage current passing through the chest for even a fraction of a second can induce ventricular fibrillation at currents as low as 60 mA, which is fatal because heart muscle cells move independently. Above the 200 mA threshold, muscle contractions become so intense that heart muscles may cease to contract.
Safety Always Comes First
In some large electrical facilities, oversight of safety regulations and negligence such as when electrical conductors are unsystematically piled in close contact, fault currents may result in ionization of the air, which in turn leads to a rapid rise in temperature and pressure, causing an explosion, commonly known as “arc-flash”
This can be avoided by taking the necessary precautions and hiring professional electrical contractors or wireman in Malaysia, such as Letrik Union, to service and install all your electrical needs.
