Fire streams cease to be effective where they lose body, direction or force. Beyond this point the water is in the form of heavy rain and is easily carried away by air currents. The point of effective reach of the fire streams tabulated above was established as the point where the slugs of water which broke away from the main body of the stream were still closely enough grouped to be effective in extinguishing a fire. As these slugs became further separated from the stream and broke into spray the stream was considered ineffective. Tests were conducted under good conditions (5 mph winds). Adverse winds will considerably reduce the effective range of monitor nozzle streams. NOTE: These are approximate distances based on available charts.
