Initial Inspection/Disposal Criteria

  1. Inspect for obvious damage, cracks, and large burrs.
  2. Inspect for gasket and screen.
  3. Inspect handle for damaged or missing screw. Ensure handle is in the correct position and turns freely into the proper positions.
  4. Inspect for fire damage. Fire damage may cause failure in the future.
  5. Inspect hose coupling threads for damage.
  6. Return to stock if nozzle is clean and shows no sign of damage or use.
  7. Refurbish if damage is repairable or if missing components are replaceable.
  8. Dispose of item if damage is excessive, or if nozzle fails Testing for Performance and deficiencies are not correctable.

Refurbishing Procedure

A. Testing for Performance

  1. Install nozzle on pump.
  2. Open handle on nozzle.
  3. Turn on water.
  4. Inspect and operate straight stream tip and fog tip ensuring neither is clogged. Clear obstructions if present.
  5. Close handle.
  6. Pressurize nozzle to 300 PSI. Test at pressure for 3 minutes.
  7. Inspect for leaks:
  • Gasket
  • Under the handle
  • At both tips

B. Cleaning

C. Repair

  1. Replace handle and ball with a new kit if needed.
  2. Replace tail gasket and/or screen if missing, cracked, or stiff. Nozzle will have a 3/16” straight-stream tip (NFES #000637) and a 2-4 gal/min fog tip (NFES #000635).
  3. Apply silicone based 0-ring lubricant to O-rings if needed.

D. Retesting

  • Following completion of any repairs, retesting of nozzles must be completed following Testing for Performance, above.

E. Repackaging

  1. Stand upright and dry completely prior to repackaging.
  2. Jute twine through valve and lower nozzle.

Please contact: Tree Felling Subcommittee

NWCG Operations Management Committee (OMC) has issued an update to the NWCG Position Task Book for Intermediate Faller (FAL2), PMS 311-91. To ensure clarity for both trainees and evaluators, the updated FAL2 Position Task Book (PTB) explicitly states who is authorized to sign off on your tasks:

“Evaluators must be qualified as a FAL2, or an Advanced Faller (FAL1).”

If you are currently working out of a previously published version of the FAL2 PTB, you do not need to restart. However, OMC highly encourages you to take the following step to prevent any confusion in the field:

  • Print and replace the updated evaluator information page (page 2) in your current physical PTB.
