Multi Protector Double Layer

The ROOTS range of products is renowned for the outstanding body burn wound results when exposed to a flash fire. We also use the same fabrics for our arc flash protection range because in a way, this is also burn wound prediction but from a different hazard source.

The goal of a burn injury prediction test combined with an open arc test is to seek prevention for wearers against 2nd degree body burn injuries. However, the nature of both tests is completely different. The burn injury prediction test measures the level of protection of a fabric/garment during a 4 second flash fire at a temperature of approximately 1000°C. The open arc test reveals the amount of energy (measured in cal/ cm2) that is needed to result in 2nd degree burn injuries, or the point at which a fabric breaks open. With an open arc test temperatures can go up above 19,000°C; with a duration of between 0.5 and 1.5 seconds. Apart from high temperature, the plasma from the melted stainless steel electrodes is also released onto the fabric.

The difference between the level of protection between the 2-layer solution (ATPV 26,8 cal/cm2) and the 3-layer solution (ATPV 51.9 cal/cm2) can be best described as remarkable, keeping in mind that there is not a genuine 3rd layer (FR underwear) with an own ATPV rating of 4.8 cal/cm2. This extra thin layer combined with the air gaps offers extra protection that is needed for a substantial increase in the total calorific rating result.
