Prop Blast/Jet Blast/Rotor Wash

 

Prop blast, jet blast, and rotor wash created by aircraft within your ramp area can cause serious injury to ramp personnel and, in some cases, cause damage to buildings, vehicles, and other aircraft.

Discuss ways to mitigate the effects of prop blast, jet blast, and rotor wash in your ramp area.

  • Are there any measures you can take to re-position aircraft to lessen the impact of prop blast, jet blast, and rotor wash?
    Examples of when prop blast, jet blast, and rotor wash can cause injury or damage:
    • There are personnel or other aircraft directly behind the aircraft.
    • When aircraft are making a turn that will affect equipment, buildings, or personnel.
  • Do all ramp personnel have appropriate and well-fitting personal protective equipment (PPE)? Does the PPE include eye protection in both high- and low-level light environments?
  • Can prop blast, jet blast, and rotor wash affect aircraft, vehicles, and personnel working behind or near your base? If so, how can you mitigate any of these effects?
  • What are your local procedures when working directly in prop blast, jet blast, and rotor wash?

LMC Equipment Bulletin 26-001: Aquatic Invasive Species – Seasonal Reminder for Mussels

Date:  July 30, 2026
Questions? 
Please contact: Equipment and Technology Subcommittee

The Logistics and Equipment Management Committee (LMC) issued Equipment Bulletin 26-001: Aquatic Invasive Species - Seasonal Reminder for Mussels, reminding the wildland fire community that aquatic mussels continue to be a problem. Mussels rapidly colonize hard and soft surfaces, including aquatic plants and fire equipment, clogging pipes, fouling motors, disrupting water systems, and impacting native species.

To help prevent their spread, fire personnel must follow the decontamination procedures outlined in the NWCG Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations, PMS 444. Additionally, report any sightings immediately to your Lead Resource Advisor and include clear, close-up photos (with a pen or your hand for size reference) and location details.”

Read the complete LMC Equipment Bulletin 26-001, to learn more.

Intermediate Faller (FAL2) Position Task Book Update

Date:  July 24, 2026
Questions? 
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.
