A Heathrow spokesperson said the check-in area at Terminal 4 was closed.

Hours after a section of a terminal at London’s Heathrow Airport was evacuated and temporarily closed due to a “possible hazardous materials incident”, the airport said that its Terminal 4 “was safe to reopen”.

“Emergency services have confirmed Terminal 4 is safe to reopen and we are doing everything we can to ensure all flights to depart as planned today,” the operator of UK’s main international airport wrote on social media.

“We are very sorry for the disruption caused, the safety and security of our passengers and colleagues is our number one priority,” the airport added.

The London Fire Brigade announced it was withdrawing its operations roughly three hours after being alerted to a “possible hazardous materials incident” at the terminal of one of the world’s busiest airports, according to AFP.

“Around 20 people have been assessed on scene by paramedics from the London Ambulance Service,” the fire brigade said, adding the cause of the incident “remains under investigation”.

Initially, Heathrow Airport said in a post on social media that check-in at Terminal 4 was closed and evacuated as emergency services responded to an incident.

“Terminal 4 check-in has been closed and evacuated while emergency services respond to an incident. Please do not travel to Terminal 4, colleagues are supporting passengers on site,” the airport said in a post on X.
