University of Waterloo in Canada
>Beth Weckman University of Waterloo in Canada, compared sofas which were purpose built, using materials compliant with the UK and former Californian standards to those from jurisdictions without such stringent furniture fire safety standards.
The tests were conducted under typical domestic ventilation conditions, rather than the artificially high ventilation of a fire test rig. The fire retarded sofas showed a slower rate of fire growth, but higher carbon monoxide concentrations than those non-fire retarded sofas.
