1.7 Mb		Occupational Injuries From Electrical Shock and Arc Flash Events
Electrical safety in the workplace is an important topic that is addressed by NFPA 70E, Standard for Electrical Safety in the Workplace® (2015 edition). This standard addresses arc flash and shock hazards, and there is a need for more empirical incident data on the actual hazards that may be experienced when equipment faults or adverse electrical events occur.

Every three years, the National Fire Protection Association (NFPA) updates NFPA 70E: Standard for Electrical Safety in the Workplace®. In recent years, the standard has become increasingly stringent in response to the increased understanding of electrical accidents in industrial plants and facilities. Because of the severe and often devastating consequences of arc flash incidents—which claim one life every workday—NFPA, along with the Occupational Health and Safety Administration (OSHA), is mandating and enforcing safer electrical work practices.

This document provides information on the most current arc flash labeling requirements, as well as best practices for creating and maintaining such labels. In the 2015 version of the NFPA 70E standard, arc flash labeling requirements are covered under Article 130.5(C) and 130.7(E)(1). Additional labeling requirements are also included in Article 110.16 of the 2014 version of the National Electric Code (NEC). This whitepaper will provide guidance for complying with both standards.

3.6 Mb		Arc Flash Hazard Labeling Do’s and Don’ts
There are as many different ways to label equipment as there are engineers and electricians in industry. Unfortunately, many of the methods being used are incorrect and may actually decrease worker safety, while increasing your company’s liability should an accident occur. This article supplies a safe-approach reference developed through years of experience working with engineers and electricians on their arc flash hazard projects. The viewpoints expressed in this paper are provided as a guide to industry, recognizing that the NEC, NFPA, and OSHA set the standards but do not cover the myriad of questions associated with labeling the different types of electrical equipment in industry.

On March 26, 2010, an excavator accidently contacted a energized 13.8 KV electrical power line. Since the contact was with one phase, the actual contact voltage to ground was 7.96 KV. When a Project Safety Representative (PSR) observed the occurrence, and saw sparks emanating from under the excavator at the time it made contact with the 7.96 KV (phase to ground) power line, he inappropriately responded by driving his vehicle near (approximately 12 feet) to the excavator. The PSR stepped out of his truck and moved toward the excavator. Fortunately the excavator driver had backed his equipment away from the power line prior to the PSR arrival.

Dear dipil,
I understand that there was some doubts about which is more dangerous to human body -AC or DC.
For ignorance we have no cure. Instead, if the engineers asked for some light we could have provided.
Electrical engineers are good at their own field - making electricity to work for them. Majority we came across had never even thought of the effect of electricity on human body. They know electricity causes shock and death. Their answers on other safety matters are often imaginary!
Now just ask them: What is ventricular fibrillation? What amount of current is required to cause ventricular fibrillation?
What is the minimum voltage at which one can feel electricity ?
What is the average resistance of human body?
What is the maximum resistance of human body?
Which part of the body has least resistance?
What is the minimum voltage required to pass sufficient current through the body to kill a person ? There are many more for a safety/Electrical engineer to understand in this field.
Coming to our issue : - Ask them what is the difference in rms value of AC and DC.
Kindly send these answers if you could get from the engineers who says DC is more dangeerous than AC on receipt of which I may be able to advise ASKCRITERION to provide the exact reasons why AC is more dangerous than DC.
Regards,
Kesava Pillai.

let me try to answer the above question,
1.What is ventricular fibrillation? What amount of current is required to cause ventricular fibrillation?

2.What is the minimum voltage at which one can feel electricity ?
1 to 8 mA -Perceptible, but not painful
3.What is the average resistance of human body?
Dry skin 1,00,000 to 6,00,000 ohms
Wet skin 1000 ohms
4.What is the maximum resistance of human body
not sure about it
5.Which part of the body has least resistance?
Ear to ear (about) 100 ohms

Dear Friends,
I always insist “while a safetyman advises others on safety issues he is not to assume things and say I think……..” He has to give a definite answer -either yes or no. Often a safety issue becomes a matter of life and death as in the case of a confined space entry or a heavy lift. We can not take chances. We have to be certain in such issues. With regard to electricity also we have to be quite serious. If one is not sure he need not be ashamed to ask for experts/consultants.
As I mentioned electrical engineers are often not trained in safety. For sure they should be trained in safety and CPR. From the replies provided by them you can see where they stand and why they consider DC is more dangerous than AC. It is their opinion only. They are not sure.
The comparison on the effect of DC and AC is attached, (current in milliamperes)
1. AC is more dangerous than DC.
2. If our AC power supply is 220 Volts (RMS) then the actual peak voltage is about 310 V.
(To get same effect of say DC 220 volts we require peak voltage of 310 in AC and we call it AC 220 V.)
3. Interference with the normal rhythm of heart causes the condition called ventricular fibrillation. In this condition fibers of the heart muscles instead of contracting in coordinating manner (which causes heart to act as a pump) contract separately and at different times. When this happens, the heart's lower (pumping) chambers contract in a rapid, unsynchronized way. (The ventricles 'flutter' rather than beat.) The heart pumps little or no blood. Blood circulation ceases and (unless proper resuscitation efforts made) death ensues. Heart cannot spontaneously recover from the condition. It is estimated that 50 ma is sufficient to cause Ventricular fibrillation.
4. 1.5 volts, a pen torch cell if touched with your tongue you feel the effect of current.
5. Average resistance of human body is considered as 1000 ohms. Internal resistance 400 – 600 ohms.
6. 6, 00,000 ohms. Skin on the palm of a village blacksmith who never used gloves in his life who can take a heated iron piece with his bare hands and sole of an old man who never used foot wear in his life. Callus – the dead cells or thickened skin on their hands and sole has that resistance.
7. Between the ears we have the least resistance of around 100 ohms only.
8. Minimum voltage required to pass sufficient current to kill a person is around 60 volts.
If the frequency is increased to thousands probably we may not even feel electricity. The normal supply frequency of 50 0r (60 as in USA) is all the more dangerous.
