Shannon Airport will host a simulated emergency response incident tomorrow morning.
Groups including Gardaí, the HSE, the Clare County Fire Service the Coast Guard, the army and more will be included.
The airport has stressed it will not impact day to day flight operations, and many passengers may not even realise its happening.
Pamela Brooks, Head of Operations at Shannon Airport, says staff taking part won't be given any details about the simulated emergency:
"We have a two hour exercise in the morning, code named Exercise Charlie."
Pamela continues to say it is being set up without giving the responders details ahead of time because it needs to be realistic.
"The scenario isn't known by any of the agencies as of yet."
The Airport's Director, Niall Kearns says this is, above all, a safety exercise.
He says, "a multi-agency exercise like this allows us to assess our readiness for any incident that may occur in real-life."
These kinds of exercises happen every two years, and must for the airport to achieve its certification.
The Director concluded, "It’s a fantastic opportunity to work with our colleagues in the local council, HSE, Gardaí, the Coast Guard, the Defence Forces, Shannon Foynes Port and AirNav Ireland and test our response to emergency situations.”
