A convenient form of cart is shown in Figure 301 (M 2-1).Each 50-foot length of hose should he laid in the top of thecart and the lower shelf used for tools, etc. For use aroundpower stations and shops it is quite inconvenient to have allthe hose on one reel. The house in which the cart is keptshould have a glass-closed opening over a spring lock, witha notice above the glass: In case of fire break glass andunlock the door. Another method is to have a sliding boltlock with a conspicuous sign: Slide this bolt to open doorand give alarm. there being another door which could be. Figure 301 (M 2-1).

The interior fire lines should be supported on brick wal
