Response
Shannon Airport’s Fire and Rescue Service was alerted and crews deployed to holding points adjacent to the runway ahead of the aircraft’s arrival.
Units of Clare County Fire and Rescue Service from Shannon and Ennis stations were mobilised, along with National Ambulance Service paramedics and gardaí.
The crew advised controllers shortly before landing that they believed the fire alarm was a false activation but said they would evacuate the aircraft on the runway as a precaution.
The flight landed safely at 6.51am and came to a stop on the runway, where the three-person crew evacuated the aircraft using an emergency slide.
Operations were brought to a standstill at the airport while the runway was blocked by the aircraft.
Airport fire crews used thermal imaging cameras to scan the jet’s fuselage externally for any hotspots, however, no indication of a fire was found.
After the crew had evacuated, firefighters wearing breathing apparatus boarded the aircraft to carry out a more detailed inspection, finding no evidence of a fire.
Flowers have caused many false fire warnings, and more than a few diversions. Some freight carriers use a supplementary procedure entailing a 20mins purging procedure with doors closed before departure.
