This is an excellent site I have used for years for my own medical info BUT I give it a B- on arc flash.  The electrical shock info is up-to-date and accurate but the arc flash has deficiencies. Click here to visit WebMD’s Electrical Injuries Article. WebMD says, “Electrical arcs: Current sparks are formed between [...]

This incident is either a utility contractor or worker most likely.  Breaking news but not clear if the worker was shocked by some backfeed source or an energized line.  This type of work is covered under OSHA 1910.269 for law and the consensus standard is the National Electrical Safety Code (NESC).  Click here to read [...]

More and more USPS facilities are being fined by OSHA.  These include many willful citations.  Inside sources claim the postal service making claim they are not covered by NFPA 70E but it is unlikely OSHA cited them on NFPA 70E. They usually recommend NFPA 70E for abatement of arc flash or electrical hazards but the [...]

This paper by Bill Jordon of Dow Chemical has long been an inspiration to me.  I know others were involved in this work at Dow like Jim Hill and Daleep Mohla but Bill’s paper and influence was recognized a few years back at the IEEE-ESW (IEEE Electrical Safety Workshop).  I had this paper for many [...]

This is a fairly common scene in spring and fall.  Powerlines and ladders or powerwashers.  Workers MUST be trained when working near powerlines, even home lines.  This is even something which commonly kills homeowners unaware. Click Here to Read the Story.

The story cites this as an electrocution but that is terminology normally reserved for fatalities.  It is common for workers in cable lines etc who are used to being “near” powerlines to make a mistake and get into one. Read the Fox News article.

Another in my series of free arc flash training.  These articles address specific issues which come up frequently in e-Hazard.com training on NFPA 70E and CSA Z462 for Electrical Safety in the workplace.

Jim Phillips has it right.  One of our first slides in e-Hazard.com Arc Flash and Electrical Safety Training developed in 2004 was a slide on using 2 levels of protection (HRC 2 and HRC 4) before doing the study using the tables for your guide and then doing the study when financing and budget made it [...]

This story doesn’t say if clothing ignited.  CPS in San Antonio, TX is in arc rated clothing most of the time.  These types of exposures are covered by OSHA 1910.269 and NESC.  Both require hazard assessment.  NESC 2007 requires protection from reasonable estimate of the energy and arc rated clothing.  More later.
