Passengers and staff were evacuated from Owen Roberts International Airport on Monday morning due to a fire alarm.
The fire alarm, which led to the airport building being evacuated for 15 minutes around 10am, turned out to be a false alarm.
Caren Thompson-Palacio, business development and marketing manager of the Cayman Islands Airports Authority, said the alarm had been set off by condensation on a beam detector in the arrivals area of the immigration hall.
She said the condensation was caused by “hot air coming in the door combining with cold air of the interior”.
Passengers who had just landed and were already in the arrivals area were evacuated outside to the controlled zone on the air side.
