OFB Foam Features and Benefits
Non-toxic yet highly expansive and effective
Environmentally friendly and Non-Toxic
OFB Foam is classified as non-hazardous according to the criteria of National Occupational Health and Safety Commission (NOHSC), and non-dangerous goods. Neither OFB Foam itself or any of its components are rated as toxic. Consequently run-off of OFB foam will not pose an environmental threat at normal dilution levels. Additionally OFB Foam is stable, non-carcinogenic, non-corrosive and readily biodegradable.
Highly Expansive and Effective
One litre of water expands to approximately 30 litres of foam using OFB CAFS systems, and OFB foam extinguishes fires over 4 times faster than plain water. It densely blankets fires to rapidly extinguish them and prevent reignition. OFB Foam also continues to smother the fuel well after the flame has gone out.
OFB foam can use fresh, salt or brackish water. OFB Foam can also be used to extinguish Class A, B, C, D & F/K fires, which include ordinary flammables like wood, paper, plastic, trash, all flammable liquids and gas like petroleum, aviation fuel and other types of hydro-carbon fires, combustible metals like magnesium, and cooking oils and fats. It requires little
cleanup and is kind to both operators and equipment.
OFB Foam has been demonstrated to meet or exceed the standards for the extinguishment of Class A, Class B and Class C fires set by LASTFIRE (Large Atmospheric Storage Tank Fires). These standards define best practice for a fire-fighting foam in the petro-chemical industry. The LASTFIRE tests were conducted at the Fiskville Country Fire Authority in Victoria in the presence of fire experts from the Melbourne University of Technology. In these tests fires in a UL certified prop, fuelled by 300 litres of heptane and reaching 800 degrees centigrade were extinguished in 13 seconds. This was an outstanding result considering that the LASTFIRE standard specifies a maximum time of 30 minutes for such a fire to be extinguished without re-ignition, and the highest marks are scored if the fire is extinguished in under 6 minutes. Consequently OFB Fire received the highest pass mark of any fire system tested.
