Are Food Trucks Dangerous?

A food cart exploded in Portland, Oregon on Wednesday afternoon, destroying two cars and damaging others in a parking lot. Fire officials say propane tanks on the cart exploded in the lunchtime blaze and they said wind caused the flames to spread to at least 10 cars in the lot. The flames started after someone who works on the cart filled a generator with gas and it spilled, authorities said. Workers tried to put the fire out with extinguishers but could not contain the blaze.
