- Abstract
- The objective of this overall project is to develop one or more alternative clean halocarbon fire extinguishing streaming agents to replace Halon 1211. In this effort a technology review was conducted and an experimental plan was prepared. Screening criteria are presented with discussions and approaches to meeting the following criteria: cleanliness, toxicity, fire suppression, ozone depletion potentials (ODPs), global warming potentials (GWPs), physical properties, availability/manufacturability, cost, materials compatibility, and chemical stability. Lists of near-, medium-, and far-term candidate agents are presented. An algorithm was developed that enables prediction of atmospheric lifetimes of hydrogen-containing one- and two-carbon haloalkanes containing fluorine and/or chlorine. Relationships are examined among C-H bond strength, activation energy for hydrogen abstraction by OH, reaction rate constants, tropospheric lifetimes, and ODPs. A review of existing and emerging technologies for the destruction of halocarbons is included.
