Ten litres of LNG was spilled but the PR at the plant first denied that anything had gone wrong (hey, there's a surprise!). It was only brought to light when Safe Haven, the LNG safety campaign group, notified the Health & Safety Executive.
Just 10 litres which 'immediately vapourised' - lucky there was no spark to ignite it as worried residents know how dangerous this stuff is. There have also been complaints about the excessive flaring and noise pollution. The risk assessment of building and running an LNG terminal in this narrow and well-used waterway, surrounded by housing, has not been made available to the public.
