A petrol leak forced the closure of the BP Garage in Yeading Lane, Northolt, for over two hours on Monday (Dec 10). Staff reportedly heard a 'hissing' noise at around 1.30pm and called the fire brigade, which immediately evacuated some nearby houses. BP also sent an emergency response team who, together with the firefighters, managed to stop the leak and clean up the damage. Liquefied Petroleum Gas is a fuel more environmentally friendly than regular petrol because it has less carbons so it burns a lot cleaner.
