Most lithium/sulfur dioxide (Li/SO{sub 2}) cells and lithium/thionyl chloride (Li/SOCl{sub 2}) cells have pressure -- relief safety devices called vents built into them. These vents are designed to open under conditions of increasing internal cell pressure. The likelihood of cell venting has been reduced to very low levels by optimizing cell designs. If fully developed Li/SO{sub 2} cells of Li/SOCl{sub 2} cells (or batteries) are discharged within the intended design limits, they are essentially nonhazardous. In addition, the consequences of cell ventings are being minimized by use of appropriate absorbant materials and protective coatings. During battery assembly and test, detection and monitoring equipment is used to sense the presence of vented gases. Tester data analysis techniques have been developed to foresee either an increasing likelihood of a vent or the presence of a vented cell. Standard cleanup procedures have been developed to safely decontaminate the assembly or test area following a cell vent.
