MOSCOW (Reuters) - Moscow oil refinery workers and firemen stopped a hydrogen leak at the catalytic cracking unit, plant operator Gazprom Neft, said on Thursday.

"There are no casualties ... the plant is working in normal mode," Gazprom Neft, Gazprom's oil unit, said in an email to Reuters commenting on the incident at the 200,000 barrels per day refinery.

It said that the staff and firemen stopped the leak and subsequent fire within 10 minutes. The oil product output process at the plant was not stopped, it added.

Earlier Interfax news agency had said Emergency Ministry staff were working to stop the leak, but a ministry spokesman denied the report.

"We had an emergency call from the refinery but soon they called again saying they didn't need any help from us," the ministry spokesman told Reuters.

In a separate incident, on Wednesday, a pump at a catalytic reforming unit at the refinery caught fire, which was soon extinguished and the unit resumed operations.

The incident happened as Moscow suffers from highest summer temperatures on record, while central Russia is caught in the deadliest wildfires in nearly four decades.
