Electrical safety and protection comes with numerous guidelines, certifications, ratings, and tests that all work toward protecting you from harm and injury. From the very beginning of any new installation, to the last transition of your power strip or outlet box, it is critical to properly protect yourself from an electrical shock should something happen. This article will give you a quick overview of what it means when you are exposed to a voltage spike, how dangerous an electrical shock actually is, and what you can do to protect yourself.

The first thing that every voltage spike checker on the job must do is check the power line for resistance. The ideal power level is a constant voltage between the positive and negative contacts of the electrical installations. When there is voltage variation between the two connections, it is known as "cross talk". Cross talk can create hazards and problems, especially for new electrical installations. Some examples of areas where cross talk may occur include loose fuses, insulation, wiring, or damaged circuit boards. It is always best to have all of these areas evaluated for resistance before any type of installation begins.
Next, all voltage spikes should be investigated using a voltmeter. The accuracy of a voltmeter is relatively high. A good rule of thumb is that ten percent of the maximum allowable voltage applied to any individual connection should produce at least one documented case of ventricular fibrillation. Ventricular fibrillation is a condition that develops when blood flow to the brain becomes abnormal. When this happens, the heart pumps harder than normal causing an increase in blood pressure, a rapid acceleration, or both.
There are numerous different types of electrical injuries. Some of the more common ones include: working on or near live electrical outlets, being on or near live circuits, working over or undervoltages, working around overloaded or high voltage power supplies, or walking under or near live electrical lines. If you are potentially exposed to any of these conditions, you should make sure you are protected with either a dust mask or eye protection. Dust masks should be worn continuously during all hours of work, and eye protection should be used at all times in over-the-counter and prescription medicines. Always be careful to follow all electrical safety guidelines while you are working.
Overhead lines, which run above or alongside buildings, provide a great deal of potential voltage hazard. Voltage induced currents (VIC) are considered the most dangerous of all VIC hazards. Indoor and outdoor installations are particularly vulnerable to high levels of indoor current. The reason behind this is that most overhead lines are designed to carry only the necessary amount of electrical current for the location they are located in. Indoor current-carrying elements, such as fridges, dishwashers, and dryers, are designed to handle only a certain amount of voltage.
When it comes to preventing the risk of high voltage-induced health and safety issues, some businesses choose to use copper cables over more modern and safer manmade fibers. These cables are also chosen over less expensive materials, such as PVC because of their ease of installation and long life span. Although, these cables have many advantages, they are not as effective at protecting personnel from electrocution as their more costly counterparts. If you are using electrical installations, you should also consider the installation of surge protectors and heavy gauge cable to protect against electricity surges. In addition, installing heavy gauge cable can help prevent short circuits and sparks from damaging electrical equipment.
