Ladder 129 was special called on the 2nd alarm fire in Camden City last night at 12:54 am. The crew was originally assigned to RIT but was relocated around the corner to put our master stream in service. The ladder operated for approximately 5 hours with multiple other agencies before returning to quarters. There was an explosion nearly injuring two Pennsauken Firemen as they were operating in their ladder. Thankfully there were no injuries from that and only damage sustained to their apparatus.
