A malfunctioning meat smoker inside Reading Terminal Market prompted a quick response from the Philadelphia Fire Department early Friday morning. The incident caused smoky conditions inside the market at 12th and Arch streets. Firefighters simply unplugged the piece of equipment and began ventilating the large indoor market. The Philadelphia Health Department was notified of the incident. "Right now they're working with building management to make sure they're open (Friday)," said Philadelphia Fire Department Battalion Chief Mike Jackson. The Easter weekend is one of the busiest for the Reading Terminal Market.
