ARC FLASH PROTECTION


OVER IN A FLASH Jarl Coldrick of ProGARM highlights the real dangers of Arc Flash incidents in the renewables sector


Recent research concluded that 70% of workplace electrical injuries are the result of Arc Flash, not just a simple electric shock. Without doubt, there is a growing awareness of the dangers posed by Arc Flash incidents in the renewables industry. As in all situations, the risk of incidents and the potentially life-threatening injuries, can be mitigated by recognising the hazards and adopting safe working practices. Unfortunately, we find a lack of consistency and knowledge about the risks of Arc Flash and assessment. Education, at all levels, is crucial for protection against Arc Flash hazards.


INCREASING AWARENESS OF ARC FLASH DANGERS


Within wind power generation, obvious risks around turbines are compounded by distribution systems connecting to the grid. The potential incident energy resulting from an Arc Flash incident is amplified by these systems, as a short-circuit in one turbine could be compounded by others online at the same time. But Arc Flash risks don’t only exist in high voltage services, you’ll also find them low voltage environments too. The Occupational Safety and Health Administration (OSHA) has highlighted that in the operation & maintenance of wind turbines, Arc Flash hazards should have the same focus as in other power generation sectors.


UNDERSTANDING THE RISKS, THE TERMINOLOGY AND PROTECTING YOUR TEAM


Arc flash garments are manufactured to protect the wearer, saving their life, or reducing the impact of any life- changing injuries.


EN IEC 61482-2:2009 is the standard


relating to protective clothing against the thermal hazards of an electric arc. This specifies the requirements and test


methods applicable to materials and garments for protective clothing, the relevant properties of the textiles tested with selected textile methods and arc thermal resistant properties.


TEST METHODS


In Europe, there are two arc test methods - open arc and box test. Open arc gives a calorific value for each garment, expressed as an ATPV (Arc Thermal Protection Value) or EBT (Energy Breakopen Threshold). The box test method gives results of either 4kA (Class 1) or 7kA (Class 2). Whilst garments should be tested in both ways, open arc is favourable as the results are more accurate.
