The device is just so small; it can be held gently in the palm of your hand. Only the thing is, you should not be the one holding it. Rather, it would be a best risk management practice to allow qualified risk managers to carry out the inspection of your electrical installations. Unless, of course, you happen to be fully qualified and certified in this area yourself. Which of course, in most cases, you are not.
It is a matter of concern to note that many business practitioners do not expose themselves to regular risk management work to rid themselves of the specter of the arc flash. Not for nothing has it been labeled a flash. Because when it occurs, that is how quickly it happens. The device used during the qualified arc flash hazard analysis will reveal the speed at which it occurs. It is over and done with within a split second.
To exaggerate in the extreme can be taken to be highly irresponsible but why not when making a very sober point. Say then that the arc flash occurs quicker than you will have blinked your eye. In fact, on many occasions it has already happened. The risk management test results will have recorded that an arc flash did in fact occur without you even being aware of it. How scary is that? Now, people as a whole may not appreciate this frightening prospect until such time that they actually experience it.
An employee or factory worker can, quite simply, be in the wrong place at the wrong time. And then it happens. He is blinded as a result. Or he loses the use of a limb. In fact, the arc flash is so hazardous it could even cause death.
