well, I am listening to Philly Fire via the internet...must be a bad feed since I cant hear much traffic. But they did say there is another hazmat incident and no hazmat units are available since they are all downtown.
It happened around 1:30 p.m. near 16th and Chestnut Streets. PECO spokesman Michael Wood told Action News that a customer incorrectly tried to switch cables, which overloaded the system sparking the fire. Wood said gasses built up causing the explosion. Several manhole covers around 15th Street blew off.
Fire officials declared the situation under control at 3:39 p.m.
