CHETAH 11.0 is a product of ASTM Committee E27 on Hazard Potential of Chemicals. The Committee is responsible for the technical content of the program and guides its continuing development. The actual implementation of changes to the program is implemented by a team at the University of South Alabama, Mobile, AL.

Dr. Larry Britton, Dr. Eidem Ural, Dr. Robert Bellair.

Special thanks to testers from ASTM Committee E27, staff of ASTM and to Dr. David Frurip.

ASTM Committee E27-07 members have provided valuable technical input to the development of CHETAH 11.0.


The development of the CHETAH program has taken place over the years with the generous support and invaluable technical assistance of a great many people too numerous to list. However special acknowledgement is in order for Dr. William Seaton who for many years spearheaded the continued development of the program.

With many omissions, others who have made major contributions to the program over the years include: Dave Fruip (Dow), Carol Davies (Dow), Gary Buckley (Cameron University), Eli Friedman (Eli Friedman and Associates), G. Hertel (University of South Florida), Josee Audet (Meck), Jeff Niemeyer (Lilly), Donna Loftin, Srinath Balaraman (University of South Alabama), Malcolm Chase (NIST), Dan Detman, and Larry Britton (retired).


In 1967 ASTM Committee E-27 on the Hazard Potential of Chemicals was formed. In 1974 the first version of CHETAH was released. In 1976 the Dudley Award was presented to W. H. Seaton, E. Freedman, and D. N. Treweek for their work on CHETAH. W. H. Seaton led the technical development of CHETAH for many years up to version 4.4. and beyond. Version 7.0 was released in 1994, it was a DOS based interactive version developed under the leadership of Dave Frurip at Dow Chemicals.

Version 7.3 was released in 2001, it is a Windows 95, NT, 2000 version developed under the leadership of B. Keith Harrison, and Banna Balaraju at the University of South Alabama.

Version 8.0 was released in 2005. This version worked on Windows systems up through XP. It was developed under the leadership of B. Keith Harrison, Abhishek Madas, and Anu Sharma.

Version 9.0 was released in 2009. It was developed under the leadership of B. Keith Harrison, Dhinakaran Srinivasan, Sreeram R. Nudurupati, Venu Madhava R. Pamera, Raghavender Erabelly, and Bharatan Vijaykumar at the University of South Alabama.

Version 10.0 was released in 2016. It was developed under the leadership of B. Keith Harrison, This version was a change to the use of Microsoft Access© platform with the logic accomplished in VBA and C code. Mr. Daniel Detman was the key person for the conversion of the Visual Basic 6 application to an Access application. The Graduate Assistants that participated in the early stage development of this version: Akilesh Akula, Rahul Badaru, and Bharatan Vijaykumar. Also Dr. Kevin West (University of South Albama) and two graduate students, Reggie Ross and Weisin Chai were involved in a project related to database development supported by Pfizer Inc.

Version 11.0 was released in 2020. It was developed under the leadership of B. Keith Harrison with key input from Dan Detman. This version incorporated the NASA Lewis Chemical Equilibrium calculations making use of the large databases of CHETAH to provide input chemicals for the calculations. This facilitated chemical equilibrium calculations in a convenient way for reactive hazards analysis.
