Unitor HotFoam Foam Concentrate 2 PCT

Verify adequate foam chemical levels in storage tanks; confirm concentrate has not exceeded shelf life (check product date codes); test foam mixing ratio accuracy with graduated measurement device

Confirm fire/foam main isolating valves are in correct position; verify fire pump operation achieves minimum main pressure of 0.6 MPa; test pressure gauges on proportioners and generators

Test foam generator production rate against nameplate specifications (UFG models: 20-60 m³/min nominal at 5-7 bar); verify proportioner delivers correct concentrate concentration (1%, 3%, or 6%); inspect for blockages in generator nozzles

Inspect all foam piping, monitor valve connections, and proportioner components for visible corrosion, scale buildup, or physical damage; check for proper coating integrity on stainless steel components; verify no leaks at connection points

Test audible and visible alarm systems for functionality; verify discharge nozzles and monitors spray pattern and reach distance; inspect eductor valve operation; perform test discharge to confirm proper foam generation and mixing (follow operational procedures to avoid directing foam at ignition sources until foam appears at nozzle)
