Abstract: The application and existing problems of compressed air foam system （CAFS） in firefighting and rescue are discussed,and corresponding countermeasures are put forward. Compressed air foam has a long shelf life and low use cost,but in practical use,there is a problem of low utilization rate. The reasons include weak awareness of the basic performance of compressed air foam among firefighting and rescue personnel,relatively cumbersome combat resupply,and more professional daily maintenance. To improve the utilization rate and firefighting and rescue capabilities of compressed air foam,the following countermeasures are proposed: strengthening professional theoretical foundation,enhancing equipment performance training,strengthening combat support,introducing intelligent management systems,giving full play to the synergistic efficiency of special equipment,and strengthening inter-departmental collaboration and information sharing.

Key words: firefighting, compressed air foam system, utilization rate, equipment performance
