LONDON, UK—FM Global, one of the world’s largest commercial and industrial property insurers, today released new research on oxygen reduction systems, finding them a potentially adequate fire protection method for certain well-sealed, unoccupied spaces.

Oxygen reduction systems (ORS) stream nitrogen into the spaces, lowering the oxygen level to reduce fire risk.

“We are cautiously optimistic about this new fire protection technology, provided the system is designed to the highest fire protection standards,” says FM Global’s Sergey Dorofeev, vice president, research area director.

FM Global details its findings, including the first large-scale fire tests involving ORS, in a new research technical report titled Evaluation of Oxygen Reduction System (ORS) in Large-Scale Fire Tests.” 

The report is available for download (PDF) at no cost and notes that ORS are not a general replacement for fire sprinklers.
