Effectiveness of Safety Interventions in Fire Engines to Reduce Potential Airborne Transmission of SARS-CoV-2

Physical distancing and wearing a face mask are key interventions to prevent COVID-19. While this remains difficult practice for millions of firefighters in fire engines responding emergencies, the delayed forthcoming evidence on effectiveness such safety setting presents major problem. In field experimental study, we provided initial close gap. We examined total aerosol burden cabin engine whilst manipulating crew size, use FFP2 respirators SCBA full-face masks during 15-min driving periods. At same time, controlled activity speaking, vehicle speed, ventilation, air temperature, pressure humidity. Limiting using not donning was associated with reduction arithmetic mean up 49%. This study reduce potential airborne transmission SARS-CoV-2 through aerosols. More research about physical clinical is needed.
