FM Global research finds ORS technology a potentially viable fire protection method
FM Global has released new research on oxygen reduction systems (ORS) in a technical report titled Evaluation of Oxygen Reduction System (ORS) in Large-Scale Fire Tests.
ORS stream nitrogen into the spaces, lowering the oxygen level to reduce fire risk.
FM Global’s research involved the first large-scale fire tests involving ORS and found these systems are a potentially adequate fire protection method for certain well-sealed, unoccupied spaces. However, the report notes that ORS are not a general replacement for fire sprinklers.
“We are cautiously optimistic about this new fire protection technology, provided the system is designed to the highest fire protection standards,” says FM Global vice president and research area director Sergey Dorofeev.
