The paper presents a system safety analysis of two air supply sub-systems which are to be used with a chemical and biological protective suit system. The backpack assembly sub-system has been developed and tested already, whereas the remote air supply apparatus has not yet been developed. The system safety analysis of each air supply sub-system includes mission analysis, preliminary hazard analysis, failure mode and effect analysis, flow analysis and fault tree analysis. A reliability model and block diagram of each sub-system is also included. The results of these analyses indicate that with proper maintenance and trained personnel the safety provided by these sub-systems should be acceptable.
