Les Quennevais Sports Centre has been forced to close following a 'suspected chemical leak'.
It's believed to have happened in a plant room at the St Brelade complex.
The Government of Jersey says no staff or members of the public have been affected, and its closure is just a precaution.
The entire centre will remain closed until it's made safe, but it's not known how long that will take.
