Introduction
Firemaster Water
Repellent Blanket is a flexible, resilient
product that is able to provide effective fire
protection in standard, hydrocarbon and jet
fire applications whilst limiting water ingress
through the use of a special additive treatment.
Firemaster Water
Repellent Blanket has all the excellent handling
and fire performance features of standard Firemaster
Blanket whilst providing excellent resistance
to water ingress due to the water-repellent
treatment being applied throughout the entire
blanket thickness. Furthermore, the small amount
of additive used ensures the blanket retains
the non-combustibility performance of the base
blanket.
Firemaster Blanket
has low density thus allowing even hydrocarbon
fire protection standards to be met using thin
and light specifications significantly contributing
to weight savings.
Health Aspects Summary
Firemaster 607 was
designed for enhanced solubility in lung tissues.
Rats have been exposed 6 hours a day, 5 days
a week during 2 years at an average concentration
of 200 F/ml (about 200 to 300 times higher
than the concentration found in production
plants) without showing any significant increase
in lung tumours or fibrosis.
