What is arc flash protective clothing?
NFPA 2112 is tyhe standard for Flame Resistant Garments for Protection of Industrial Personnel Against Flash Fire. The standard is targeted towards workers who are at risk of flash fires, primarily in the petrochemical industries.
At what voltage can arc flash occur?
Most 400 V and above electrical services have sufficient capacity to cause an arc flash hazard. Medium-voltage equipment (above 600 V) is higher potential and therefore a higher risk for an arc flash hazard.
What are the arc flash boundaries?
The arc flash boundary is the minimum “safe” distance from exposed energized conductors or circuit parts that has the potential for an arc flash. Arc fault incidents happen daily in the United States. Take the proper steps to ensure your safety before taking any measurements, especially on energized equipment.
At what voltage does an arc flash hazard not exist?
In general, arc flash incidents are highly improbable on systems operating at less than 208 volts phase to phase (120V to ground) when fed by less than a 125 KVA transformer (very typical of most office and home environments). 120 volts does not provide sufficient energy to cause an arc flash hazard.
How many times can you wash arc flash clothing?
There are many different FR fabrics in use now, and each has a different lifespan. The general rule of thumb is to own 5 sets of arc flash clothing, with each set being washed and worn once per work week.
