A Royal Mail sorting office has been closed after a cleaning product spill from a package.
Five engines from Hampshire Fire & Rescue Service, two ambulances and police were called to the building on Mill Road, Gosport at 11.20am.
The Hazardous Area Response Team (HART) from South Central Ambulance Service were also sent to the scene following reports that workers at the sorting office had found a package containing a bottle containing approximately 500ml of an unidentified liquid.
The liquid inside the bottle then spilt on the floor causing nausea, headaches and eye pain/itchiness to workers.

On the arrival of the Hazardous Area Response Team, the effects on two patients had started to pass and they were feeling better.
After investigating, HART discovered that the mysterious chemical was in fact aluminium wheel cleaner, and is not a hazardous substance.
It is not believed the affected workers will require hospital treatment after being assessed and monitored at the scene.
The sorting office has a notice on its entrance, which reads: ‘Unfortunately due to health and safety, this office is closed temporarily’.
A member of the public, who did not want to be named, said that he was going to the sorting office to collect a recorded delivery before being told by a member of staff that the office would be closed for at least the rest of the day.
