OK, it isn't as bad as the headline suggests but a number of staff working at the 02 Arena (which was London's Millennium Dome) were hospitalised after an ammonia leak.

OK, it isn't as bad as the headline suggests but a number of staff working at the 02 Arena (which was London's Millennium Dome) were hospitalised after an ammonia leak.

Emergency services were called to the south west London venue at 8.30pm after ammonia gas leaked into the arena where staff were dismantling stage equipment. Four fire engines and several support units from five fire stations in Greenwich and the surrounding area attended the scene closely followed by fifteen ambulances and five vehicles from the London Ambulance Service's Hazardous Area Response Team. Twenty-nine people were taken to hospital suffering from symptoms such as nausea, difficulty breathing and eye irritation but were all treated and discharged the same night. No members of the public were affected. The O2 opened the following day as usual. The gas is believed to have leaked from the ice rink plant room. An internal investigation is being carried out into the cause of the incident.
