Oxygen reduction systems (ORS) stream nitrogen into the spaces, lowering the oxygen level to reduce fire risk, according to the research from commercial and industrial property insurer, FM Global

New research on oxygen reduction systems has found the systems could potentially be an 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, according to the research from commercial and industrial property insurer, FM Global.

The research follows several high-profile deadly fires in 2017, including the Grenfell tragedy in the UK and a shopping mall fire in the Philippines, which turned risk managers’ attention to dangers lurking in plain sight.

“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 available here.
