The jactone has the essential performance requirement in that it must extinguish a cooking oil fire (as detailed in BS EN 1869:1997). To achieve this, the fire blanket must be flexible, with good draping qualities, to eliminate oxygen from the burning oil and to allow the oil to cool gradually to below its self-ignition temperature. It should not reignite when the blanket is removed after 17 minutes Our 1.1m x 1.1m premium fire blanket has a unique 3-ply material; two layers of woven glass fibre fabric with an inner layer of fire retardant film and it is this construction that is at the forefront of the fire blankets unblemished safety record.
