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?
