Seneca Hose was recently dispatched to a propane emergency on Benson Ave off of Seneca. Seneca Hose Engine 2 arrived and found a large propane tank that was just filled actively leaking from a pin hole in the top side of the tank. Engine 2 requested Erie County's Hazmat Team to assist with mitigating the hazard as well as Reserve Fire to assist with evacuating the lower half of Benson Ave.
