What is the life expectancy of arc-rated protective clothing?

Life expectancy of arc-rated protective clothing

There are two types of clothing to which this discussion applies; one known as Flame Resistant (FR) and the other known as Arc Rated (AR). The difference is significant. All AR clothing (ARC) is FR rated, but not all FR clothing (FRC) is AR rated. The two types have different standards to which they must comply. ARC is not only flame resistant; it must also withstand the extremely high momentary temperatures generated by an… Continue Reading »

Choosing the Right Ground Resistance Tester

Ground Resistance Tester

There are a wide variety of ground resistance testers available on them market today. These vary in design, features, and complexity, and include small handheld models as well as larger field instruments that are often packaged as part of a complete kit. These products also range in price, from few hundred up to several thousand dollars.

In this article, we discuss several critical questions to consider when selecting a ground resistance tester…. Continue Reading »

Digital Meter Provides Better Accuracy

Use the Hastings 6702 Digital Voltage Phase Meter to make sure you have voltage on both sides of power line switches/cutout fuses and check all the phases.  With the digital readout you see the small differences in the voltage reading.  Both sides of the cutout fuses should read zero volts but could possibly show 200-400 volt fluctuations.

Important Keys to Ensure Worker Safety

No matter how good the equipment, there is always a chance of an arc flash occurring when an electrician works on switchgear or even just turns it on. Temperatures of an arc flash can reach upwards of 35,000 degrees in less than a second, burning a person directly or causing ignition of non-flame resistant clothing or the melting of clothing into the skin. So it is very important to… Continue Reading »

Arc Flash Hazards and the Electrical Thermographer

The goal of any electrical thermographer is to prevent unplanned shutdowns in a manner that is reliable, repeatable and above all safe. Since thermographers work with the target equipment online and on load coupled with the fact that IR Cameras cannot “see” through panel covers, thermographers face severe safety hazards when attempting to scan electrical distribution equipment. Taking measurements with a cover removed is not a safe option…. Continue Reading »

Electrical Safety in the Workplace Pt 2: NFPA Compliance, Arc Flash Analysis & PPE

NFPA 70E – The Safety Standard

NFPA 70E defines the safe parameters for personnel working on electrical equipment. Although adherence is not a legal requirement, the standard provides a benchmark for most industries to demonstrate compliance with OSHA’s General Duty clause. An employer adopting the guidelines offered in NFPA 70E demonstrates a clear commitment to safe working practices and the protection of employees from shock and arc flash hazards.

According to the standard, if personnel will… Continue Reading »

Electrical Safety in the Workplace Pt 1: Arc Flash

Concerned About Arc-Flash and Electric Shock?

Electrocution is the obvious danger faced by anyone working on or near live electrical equipment and it is clearly important to understand shock hazards and wear appropriate protection. However, most electrical accidents are not the result of direct electric shocks. A particularly hazardous type of shorting fault—an arc fault— occurs when the insulation or air separation between high voltage conductors is compromised. Under these conditions, a plasma arc—an “arc… Continue Reading »

10 Dumb Things Smart People Do When Testing Electricity

Anyone who makes their living by working with electricity quickly develops a healthy respect for anything with even a remote chance of being “live.” Yet the pressures of getting a job done on time or getting a mission-critical piece of equipment back on line can result in carelessness and uncharacteristic mistakes by even the most seasoned electrician. The list below was developed as… Continue Reading »
