Comfortable arc flash protective clothing
23 January 2013
J & K Ross and DuPont Personal
Protection have developed
ARCBAN, a range of CE certified arc
flash protective garments that are
made from Nomex. Following a
comprehensive risk assessment study
and implementation of risk
J & K Ross and DuPont recommend that all the layers including undergarments are made of Nomex which is an inherently flame resistant meta-aramid fibre that does not melt, drip or support combustion in the air. The thermal behaviour of Nomex is due to its molecular structure and not by applying a flame retardant chemical substance to the fabric, yarn, fibre or polymer. This means that Nomex offers permanent protection that cannot be washed or worn away.
The ARCBAN range offers head to toe solutions providing various levels of electric arc protection and includes undergarments and specialised workwear along with head and face protection that can be worn with appropriate face visors and helmets.
Flame resistant (FR) clothing can be rated based on its Arc Thermal Performance Value (ATPV) in cal/cm2. To properly protect a worker, the ATPV rating of the FR clothing must exceed the calculated prospective incident energy caused by an electric arc flash event onto the worker at a given location. Layering the garments can help to increase the ATPV levels due to the air gaps in between the garment layers. It can also help with matching the hazard and risk with the appropriately designed PPE resulting in the wearer having more fit for purpose and comfortable solutions for the required hazardous environment.
For example, you might choose to use the ARCBAN polo shirt and trousers as standard, everyday FR workwear because it is practical and comfortable to wear and when in a higher risk environment, layer up with a coverall resulting in the combination of these two layers providing higher ATPV values. To attempt to achieve this combined result with a single layer fabric solution may result in the clothing being very heavy and uncomfortable to wear for a full shift.
All the garments are CE certified and allow the user to select the correct level of protection for their risk, avoiding heavy and uncomfortable protection.
