Electrical Contractor Malaysia | Electrical Engineering

February 1, 2020

In definitive terms, electricity is a form of energy resulting from the interaction of charged particles and is the power source of most of today’s appliances; whereas electrical simply means relating to or concerning with electricity. The utilization of electricity is undoubtedly indispensable in today’s rapid-growing development of industries, agriculture, enterprises, construction and every other power-consuming sector. It is deceiving to assume that electrical work is as simple as connecting wires from the positive to the negative terminals, but as a matter of fact electrical work covers a wide scope including supply, installation, testing and commissioning of all conduits and accessories, wiring, switches, socket outlets, spur outlets, junction boxes, GI pull wires, ceiling connections and plenty others. Performing electrical work is a high-risk job no matter the scale of the matter and requires professional assistance such as electrical contractors that is well equipped with the complexity of electrical wiring and experienced with the power utility layout of the construction. To be aware and well-informed of the degree of complicacy in electrical issues is pivotal for everyone’s safety and well-being, Aathaworld Sdn Bhd is an electrical contractor in Malaysia and expertise in electrical solutions for industries of every size and models.

Understanding the dangers of electrical risk

Electricity, when tempered without proper guidance, poses a dangerous threat as it is nearly impossible to detect the presence of volatile utility supply through scent, sight, or sound, and as such electrical hazard can occur seemingly without prior warning. Such risks inherent to electricity include electric shock, physical burns, psychological and neurological damage, ventricular fibrillation and ultimately resulting in death. There are also frequent cases of mishandling of electricity that have caused indirect damages in the most deplorable manner, such as an explosion, a fire or a fall. An approximate gauge of the minimum current a human is able to feel is about 1 milliampere (mA), while at a slightly higher rate of 80 mA, electricity can seize the heart muscle, causing tissue damage or heart fibrillation in accordance to electrical contractor Malaysia. The implications of an electric shock are different according to the voltage, duration, current, path taken and frequency. To put into perspective the severity of an electrical shock, 100 mA of electricity coursing through a human’s body for as long as two seconds freezes the muscles of the arms and legs; extended exposure can lead to respiratory paralysis and inevitable death. High-voltage shocks propagate a large amount of energy causing internal burns and are highly fatal should the electricity path crosses vital organs such as the heart. On the other hand, a low voltage current through the chest for even a fraction of a second may induce ventricular fibrillation at currents as low as 60 mA, which is lethal as heart muscle cells move independently as per experienced talk by electrical contractor in Malaysia. Above the 200 mA threshold, muscle contractions become increasingly strong that heart muscles may not even move at all. 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”. These unforeseen circumstances can be prevented by taking proper measures and hiring professional electrical contractors Malaysia such as Aathaworld, to service and install all your electrical needs.
