S woke me to tell me what had happened - it was pretty early- soon after 6.00 I think. We weren't woken by the explosion like some people though.
However - by about midday there was a definite smell of petrol in the air.
By dusk - the smell of burnt petrol was unmistakable - we couldn't have windows or doors open on that side of the flat.
Fortunately the wind changed direction the next day towards the south west. The sun came out and it didn't rain on us. Once it raisn on us our water will be contaminated with benzene, which is extremely toxic, even though we breathe it in every day coming out of exhaust pipes.
