Arc flash analysis is another one of those extremely serious hazards which are all too often overlooked by safety teams. Part of the reason for this is the complexity of the rules regulating arc flash, and part of the reason is the fact that OSHA does not directly regulate it. Instead, OSHA relies on NFPA 70E to set their requirements. So, if you are just setting your safety plan based upon OSHA standards which are pertinent to your business, it is very possibly to completely bypass the arc flash requirements.
First and foremost, when establishing arc flash procedures, it is crucial to at least consult with a professional firm which has experience in this arena. Arc flash rules can get extremely complicated, especially for larger companies with more machines, and shortcut guides can often lead to errors. For instance, IEEE 1584 is a common guide used to calculate arc flash hazards, but it is incomplete in several ways and many companies which use only IEEE 1584 guidelines are not actually safe or compliant.
After establishing where there are arc flash hazards, it is important to put proper signage in place. These signs warn employees of the dangers of the machines, and explain how to prevent injury. Without proper signage, arc flash analysis does nothing to help protect employees, and it is important to make sure the correct signs with the correct information go in the correct places.
