Appendix G – ChemLogic Cassettes 

 
DOD ChemLogic

 

cassettes are designed for use in colorimetric based gas 

monitoring systems.  Since this is a particular end-use function and does not release 
or result in exposure to hazardous chemicals under normal use Material Safety Data 
Sheets (MSDS) are not required.   
 
ChemLogic cassettes are non-toxic and require no special precautions for 
protection.   However contact with skin may cause the cassette to react, change 
color, and no longer be useful in your gas monitoring system.   We therefore 
recommend that rubber gloves be worn at all times while handling including removal 
and installation.   Always wash hands as a precaution after handling DOD Chemlogic 
cassettes.
