This pre-study aims to determine whether developing measurable sustainability indicators (MSI) to assess the sustainability of projects, ideas, and decisions related to fire safety would be useful for fire safety engineers, researchers, municipalities, authorities, policymakers, first responders and other stakeholders. A review of the literature, online sources, project reports and numerous interactions with representatives of several target groups within the fire safety community were conducted to assess their sustainability needs. The results show that the target groups included in this project had some overlapping and some unique sustainability needs. Fire service product suppliers are content at this time to self-declare their sustainability status. Fire and rescue services would like MSI to help them make tactical and strategic decision while responding to fires. They are also interested in MSI to help them convey their sustainability value to the communities they serve. Fire safety engineers would like MSI to support their suggestions for improvements in construction design. Researchers and educators will contribute to the development of MSI that serve the needs of the other target groups. Authorities could use MSI to evaluate progress toward improved sustainability in their jurisdictions and transfer data to other levels of government.
