Boeing's findings and recommendations on electrostatic sprayers

In response to the global COVID-19 pandemic, airlines are looking for ways to efficiently and quickly disinfect the aircraft's interior. One proven method is the use of electrostatic sprayers - semi-automated devices that deploy liquid disinfectant into a spray form. Boeing researchers studied the use of electrostatic sprayers to determine best practices and provide recommendations for reliable disinfection of the aircraft's interior.

Electrostatic sprayers have an advantage over the more traditional manual applications of disinfectants by using a spray bottle and cleaning cloths because the electrostatic sprayer allows a large area to be covered with a disinfectant uniformly and very quickly. Consistent results rely on the uniform spray style by the operator including factors like the application speed and distance to surface. As a result of this study, the Boeing research team is making several recommendations to airline customers including:

  • The type of semi-automatic spray device to use (including devices with variable nozzle sizes)
  • The distance, angle degree and speed of the spray application
  • The humidity and temperature range of the airplane environment during application

These recommendations come from a comprehensive set of tests conducted by Boeing's Confident Travel initiative (CTI), which is executing a multi-layered approach to the COVID-19 pandemic. The CTI team works with airlines, global regulators, industry stakeholders and academics to establish industry-recognized safety recommendations. Through scientific studies like this, Boeing is helping ensure airlines have the tools needed to provide clean and safe airplanes for the airline crews and traveling public.
