Electricity…Electricity…Electricity…we cannot live without it! Electricity is so embedded into the fabric of our lives that we often take it for granted without notice of its significance. Before you go to bed tonight walk through your living quarters and take notice of the green, red and orange LEDs peering at you from dark corners – electricity busy at work while we sleep.
In the refrigeration world, our wonderful compressors are not very useful unless they have a reliable and safe supply of electricity. For the most part, we rely on our local electrical utility to provide us with a reliable, clean and secure electricity supply. As far as safety, in the United States, we have codes, standards and certifications such as National Fire Protection Association 70 National Electric Code, National Fire Protection Association 70E Standard for Electrical Safety in the Workplace, Occupational Safety and Health Act and Underwriters Laboratories that protect us from the potential dangers of electricity such as shock, fire and explosions from an arc flash event.
While it is true that energized components and conductors are usually safely mounted in enclosures, there are times when those of us who work in the industrial and commercial refrigeration industry need to interact with, and actually touch energized components with meters and tools when trying to troubleshoot or repair equipment. This can be a very dangerous task and is a primary concern of ours when designing and building electrical equipment.
So, we would like to hear from you – what are you doing in the workplace to safely handle electrical hazards? Do you understand NFPA 70E? Are you complying with NFPA 70E?
Vilter Manufacturing will have a booth at the upcoming Refrigeration Engineers and Technicians Association 2012 National Conference in San Antonio, Texas from November 5-9. We will have our NFPA 70E inspired motor starter with us and I will be presenting a short piece on our motor starter on Friday morning November 9th.

I hope to hear from you soon – stay safe!
