Five people were taken to Boston hospitals Thursday morning after a fire-retardant system discharged at a car rental facility at Logan Airport in East Boston, officials said.
The incident took place at a Hertz location on Tomahawk Drive and led to three people being transported to Massachusetts General Hospital and two people being taken to Tufts Medical Center by Boston Emergency Medical Services first responders, EMS spokeswoman McKenzie Ridings said.
The incident occurred at the “fuel pumping area,” said Paula Rivera, a Hertz spokeswoman.
“No employees were seriously injured, however, as a precaution, we sent a few employees to the hospital,” Rivera’s statement said. “Additionally, we’re working with local authorities to investigate the incident and are in a cleanup phase. Overall, this . . . has had little impact on our operations.”
Firefighters from Logan Airport responded to the scene around 8:37 a.m., Massport spokesman Matthew Brelis said.
The cause of the incident is under investigation. The fire-retardant system uses a chemical similar to baking soda, Brelis said.John R. Ellement can be reached at ellement@
