Calculating the potential behavior of an arc flash provides insight into risks and how these can be minimized. By understanding the arc flash energy at a specific location, the correct personal protective equipment can be determined and used and you can perform changes on the installation to turn unsafe cases into safe.
European-based plants/companies must follow the EU methodology, as workers must wear European-certified clothing. US-based companies follow the US standard, which has been in place for some time, and is often used for offshore companies and yachts. According to the European methodology, arc flash calculations and PPE must be included on arc flash labels. However, there is no fixed guideline or standard that determines what should be included on these labels. In our opinion, certain information should be added to ensure that the worker is aware of possible risks and follows safety measures.
HyTEPS places additional information on EU labels. This can be adapted to the customer’s wishes. However, some basic information is always present.
– Warning sign with orange background indicating arc flash and shock hazard.
– Indication of distribution board.
– Electric shock level [V].
– Arc current [kA]
– Arc energy [kJ]
– Working distance on which calculation is based [mm].
– PPE Mandatory use sign and certified European logo that clothing must comply with (CE).
– Class level [1 or 2]
– HyTEPS and customer logo
– Clothing to be worn near a closed/open distribution rack
– Simulation date and ISO number.
– Warning message as used on the US label
