China New Rescue Firefighting Closed Foam Water Spray

new rescue firefighting closed foam water spray
Product Description
The foam bladder tank, together with ratio controllers, form a balanced pressure proportioning system used to mix water and fire fighting foam together to generate an effective extinguishing medium.
The bladder tank technology is a reliable and precise mixing method that is widespread in the fire fighting industry. This method allows the water/foam ratio to remain stable by automatically adjusting to the variable flow rates and pressure conditions that may occur during system operation.
This feature makes bladder tanks particularly suitable for multiple hazard systems, sprinkler systems and any other system operating under variable, non predictable, flow and pressure conditions.

Procedure:
1. Isolate the foam agent tank from the firefighting system. Follow appropriate instructions and/or manuals
related to the specific system.
2. Relieve pressure from any pressure vessel through the shell vent valve on the top of the tank.
3. Completely drain the water from the shell of any bladder tank in accordance with appropriate procedures.
4. Transfer the foam agent to be replaced from the tank into suitable storage containers. Use a transfer
pump where applicable. Refer to the manufacturer's manual for specific draining procedures. Properly
label temporary foam agent storage containers and dispose of the foam in accordance with local regulatory
authority requirements for chemical labelling and disposal.
5. Rinse the foam agent tank with clean fresh water and drain. Open all tank fill, tank return, and drain lines
while rinsing to remove any accumulated surface residue and help prevent cross contamination. Be sure to
collect and dispose of drained rinse water in accordance with applicable local regulations. Repeat this process
with fresh water to ensure the internal tank surfaces are clear of any accumulated contaminants.
6. Close all valves to ensure the foam tank system is a closed circuit.
7. Fill the foam agent tank with clean, fresh water to a level that ensures all connecting pipework is flooded.
For bladder tanks, be sure to use appropriate fill procedures so the bladder is not damaged.
8. once all pipework is flooded, open and close all valves to allow valve seats to be rotated within the freshwater.
Systems involving foam pumps should be operated in a recirculating circuit to flush the entire tank,
pump and return lines. Please note that some systems may have extensive foam agent pipe runs between
the foam tank and proportioning device(s). Those systems may require partial- to full-firefighting system
discharge to flush foam agent from the pipework. Follow applicable system instructions in those cases.
9. Drain the foam agent tank and associated piping and dispose of rinse water in accordance with local
regulations.
10. Typically, a discharge of foam solution may result in foaming or bubbling of the rinse water solution. Repeat
steps 7 through 9 as many times as needed until no evidence of foaming or bubbling is occurring in the rinse
water or until the AHJ is satisfied.
11. For bladder tanks, perform a bladder integrity test following the procedures outlined in the bladder tank
operation and maintenance manual.
12. once the tank interior is cleaned, emptied and approved for use, refill the tank with the new foam agent in
accordance with appropriate filling procedures.
13. once the tank is full, place the system back into service using the guidelines outlined in the manufacturer's
operation and maintenance manual.
14. Verify that all components of the system match the foam agent approved for use (i.e. proportioner orifice
size, discharge devices, etc.).
15. Ensure appropriate labelling is added to the newly-filled tank to identify its contents. Add the correct safety
datasheet (SDS) to the manifest at the system location or on the mobile apparatus.
