Final Report: Effective Non-Toxic Metallic Fire Suppressants

The purpose of the project was to: a.) identify which metal species would be effective flame inhibitors, and then b.) attempt to find non-toxic forms of the metal which could be used. Very early in the project, however, we determined that metal species-in any form-might not be effective in practical flames. This in itself was a major finding, and hence an additional, most important objective of the project became: c.) determining the reasons for the unexpected low effectiveness of Fe(CO)5 in cup-burner flames.
