Narrative
On 1/27/2022, a city of baltimore contractor was welding on a water main on frederick avenue near the intersection of boswell road. While performing the welding operation, an ignition occurred which caused a nearby manhole cover to raise and strike a nearby contractor, causing injury to the contractor's foot and requiring overnight in-patient hospitalization. Natural gas was confirmed in the localized area and surveys were immediately conducted to find the source of the leak. An adjacent medium pressure 12" cast iron natural gas main was found to have two leaky joints and they were subsequently repaired as well as renewing an interconnected natural gas service line. Post-incident surveys were completed, and no readings were detected such that the job could be closed out.. Note : part a 21c is noted as 0.0 however actual (mcf) is 0.003.To match part a 7.
