More than 130 people have been treated in hospital after a suspected chemical leak along the East Sussex coast.

Birling Gap beach was evacuated on Sunday after people reported breathing difficulties, stinging eyes and vomiting when a “mist” appeared.

Investigations are under way into the cause of the “chemical haze”, which is currently unknown, Sussex Police say.

Beaches in the area are expected to be open as normal on Monday, although the situation will be monitored.

Police say the believe it came in from the sea – previous incidents have involved something coming over from an industrial unit in France – but this has yet to be confirmed.

‘Decontaminated’

A police spokesman said the first report came in from Birling Gap just before 17:00 BST where “up to 50 people had been affected by irritation to eyes and throats”.

The plume of gas moved eastwards along the coast as far as Bexhill, police said.

Coastguard rescue teams from Birling Gap, Eastbourne, Bexhill and Newhaven raced to help clear the busy beaches as visitors feared they had been struck by a chlorine leak.

As of Sunday night, 133 patients were being “decontaminated” at Eastbourne District General Hospital, according to East Sussex Healthcare NHS Trust.

The police said the effects, while uncomfortable, were not serious, and East Sussex Fire and Rescue Service said it was “extremely unlikely” the substance involved was chlorine.

Kyle Crickmore, who was at the Birling Gap beach with his family, said it emptied in 10 minutes after people began to feel unwell.

He described how a “foggy haze rolled in out of nowhere” and there was a “strong smell of chlorine in the air”.

“It was definitely out of the ordinary considering it was a nice clear sunny day 10 minutes beforehand,” he said.

“It was stupidly busy and it was a boiling hot day.

“It emptied in about 10 minutes, which was quite staggering considering the amount of people who were there.”

Members of the public alerted emergency services, which triggered call-outs to the UK Coastguard, Sussex Police, South Eastern Ambulance Service and East Sussex Fire and Rescue Service, who said they were treating it as a “chemical incident”.

The RNLI said that “possibly some kind of gaseous fumes” had drifted over and a significant number of people on cliff tops had been struck down with symptoms including irritation, sore eyes and vomiting.

Dan Sankey wrote on Twitter: “Beautiful afternoon at Birling Gap cut short by some weird mist, burning everyone’s eyes which led to the beach and cliff being evacuated.”

The beachfront is a popular hot spot for tourists and locals on bank holidays.

People living along the coast have been advised to keep windows and doors shut since the incident.

Thousands of people are expected to head to the coast again on Bank Holiday Monday.

The beaches in East Sussex will be open as normal, police said – and there were no officers at the scene by Monday.

They said it was believed that this was an “isolated incident and is not expected to recur”. Continue reading.
