A chemical leak at an Amazon depot has led to several people being treated for facial injuries.

The incident happened early today at the company's London Medway Commercial Park site on the Hoo Peninsula.

An Amazon spokesman has said a full investigation is under way into the circumstances.

It is understood the incident involved a HGV trailer which had arrived on the site, which remains fully operational.

The vehicle did not enter the warehouse and stayed outside in the yard.

Police, ambulance and firefighters were called at about 3.45am and checked over several people.

Ambulance spokesman Rich Airey said: "Crews attended the scene and checked over a number of people for irritation to their eyes, nose and mouths.

"No one required further hospital treatment. Two patients had previously self-presented at hospital."

Fire crews remained at the scene until 12.10pm. The area was closed off with police sealing the area around the Stoke Road and Eshcol Road roundabout.

Hazardous materials officers and an incident support unit from the fire service supported specialist paramedics from the South East Coast Ambulance service HART (Hazardous Area Response Team) unit.

A fire service spokesman said: "Crews carried out chemical tests at the scene after a number of people reported irritation to their eyes, nose and mouths. We are awaiting the test results, however there is no risk to the public.”

The two Amazon workers who went to hospital have since returned home.
