National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Modeling downwind hazards after an accidental release of chlorine trifluoride.

DE96008618

Publication Date	1996
Personal Author	Lombardi, D. A.; Cheng, M. D.
Page Count	16
Abstract	A module simulating ClF3 chemical reactions with water vapor and thermodynamic processes in the atmosphere after an accidental release has been developed. Initial model runs simulate the rapid formation of HF and ClO2 after an atmospheric release of ClF3. At distances beyond the first several meters from the release point, HF and ClO2 concentrations pose a greater threat to human health than do ClF3 concentrations. For most of the simulations, ClF3 concentrations rapidly fall below the IDLH. Fro releases occurring in ambient conditions with low relative humidity and/or ambient temperature, ClF3 concentrations exceed the IDLH up to almost 500 m.
