Safety training is a fact of life for employers. It is essential for several reasons: the Occupational Safety and Health Administration mandates it, and more importantly, offering safety training is the right thing to do.
Electrical safety is a topic worth discussing repeatedly. Both government and private organizations cover it. The Occupational Safety and Health Administration (OSHA) has developed regulations addressing electrical hazards.
A lot can happen in two seconds. What may seem like the blink of an eye can feel like an eternity, especially during an arc flash. When calculating the incident energy as part of an arc flash study, sometimes the IEEE 1584 equations can produce unusually large values.
Conducting a fire alarm system acceptance test in front of a fire official can prove daunting, even when the system passes muster. But doing any form of fire alarm system testing without having the proper tools is downright foolish.
Every work site has flammable and combustible liquids. A flammable liquid is much more volatile than a combustible one, meaning its vapors or fumes can ignite at temperatures below 100°F and some even lower than 32°F.
There seems to be no end to studies and theories on education and training that focus on methodology and effectiveness. Yet, for the lay person who simply wants the basic questions on safety training answered, they offer much more than is needed.
One sentence in the IEEE 1584 Standard, IEEE Guide for Performing Arc-Flash Hazard Calculations, frequently has people scratching their heads: “Equipment below 240V need not be considered unless it involves at least one 125 kVA or larger low-impedance transformer in its immediate power supply.” Wha
For a long time, “going green” was used by hippies and tree-huggers. However, greening has become more mainstream and more necessary for businesses to remain competitive. Your business and the environment are more closely linked than you may think.
Knowing how long an arc flash could last is the most important piece of information in predicting its severity. The duration is usually dependent on how fast an upstream protective device will trip. The longer it takes, the greater the incident energy and resulting hazard.
Simply stated, a job hazard analysis (JHA) is an organized look at what could cause harm to employees in the workplace and work activities. It’s a way to determine if you have taken sufficient precautions to keep your people safe or if more needs to be done.
During my career, I have encountered many electricians and engineers who considered installing power quality monitors to be a nonhazardous job that requires nothing more than hooking up the voltage clip leads and putting on the current probes to the proper conductors.
On the job, We pay close attention to numerous electrical safety basics. This is a good thing. Unfortunately, we seem to forget all about many of these once we get home. Although safety is very important on the job, safety at home is just as crucial.
Much has been written about the dangers of electricity and the importance of following proper work practices. This includes the use of personal protective equipment (PPE), which is the last line of defense. Clothing is somewhat of a different story.
